The Neglected Secret to Making Dungeons Fun to Explore

The best dungeons build on the three Dungeons & Dragons pillars of combat, roleplaying interaction, and exploration—a pillar that depends on discovery. Dungeon creators rarely slight two of the pillars: Monsters engage characters in combat. Non-player characters and factions lead to roleplaying interaction. But for the last pillar of exploration and discovery, dungeon designers often stop at the map, and that counts as neglect. Interacting with a floor plan gets tiresome fast.

To engage players in exploration and discovery, dungeons need more than listings of rooms and inhabitants where characters open a door and discover their next opponent.

Typically, dungeons also feature a history as a tomb, wizard’s tower, cursed underground city, or the like. But while such themes add flavor, this mere color rarely includes enough discoveries to capture hours of attention. Dungeons need interactive features that give players the underrated pleasure of figuring things out, of trying things and discovering how the dungeon and its contents work.

The fun of exploring a tomb comes from interacting with the traps, puzzling inscriptions, and blessed shrines inside. The fun of a wizard’s tower comes from playing with the magical whimsy and the experiments gone wrong. The fun of lost city comes from the magic fountains, secret ways, and so on.

Whatever the location, dungeons need interactive features that characters can play with like toys, things that fire the player’s curiosity, and then invite the players to touch and experiment. Sometimes the toys might prove dangerous, other times they can reward with treasure, blessings, or useful information, but players who discover how something operates always feel rewarded for their brains and ingenuity. Good exploration leads to the powerful reward of such discoveries.

Adventure designer M.T. Black writes, “Adventures thrive on interactivity. Without it games become uninteresting. This is a big part of the exploration pillar of play, and I think it is neglected. Pick up the diary and it grows legs. Touch the holy orb in the chapel and a glass knight steps out of the window. The treasury looks empty but actually has an invisible treasure chest.”

When I first started creating dungeons, I aimed to pack my locations with the sort of lavish, interactive rooms in adventures like the Tomb of Horrors and White Plume Mountain. Preparing for a single session took me hours of dreaming up elaborate locations that could confound and impress my players. I soon learned that I lacked the time to invest in so many detailed designs. Later, I found that I didn’t need to, because smaller, simpler toys can work as well. Every parent has unpacked and assembled an extravagent toy, only to see their kids become captivated by the box. Many players like me also become captivated by the boxes—or pools, orbs, runes, statues, and so on. All those things prove fun as long as playing rewards us with discoveries.

Now when I design dungeons, I focus on including things that both invite interaction and lead to discoveries. So, the pool might include and underwater passage that leads to another room. Or it might contain acid and a glass vial containing a map to a secret treasure room. Or it might bubble with fumes that make characters lightheaded enough to see a vision of a similar room elsewhere. The best toys often mix danger and reward, so those fumes might make characters fall unconscious, and then see visions as they start to drown. Surely someone in the party will save their dreaming friend.

Dungeons packed with such features feel like more than maps with monsters, they feel like toys that reward play with discovery.

Just Because a Dungeon Numbers Every Room Doesn’t Mean Players Have To Explore Room-by-Room

If I had run Expedition to the Barrier Peaks when it reached me in 1980, the first session might have ended in frustration. Barrier Peaks includes lots of empty rooms. Of the 100 or so rooms on the first level, fewer than 20 contain anything of interest. I would have dutifully let the players poke through 80 rooms of “jumbled furniture and rotting goods,” gaining “only bits of rag or odd pieces of junk.” Two hours into that grind, my players would suddenly remember that their moms wanted them home.

Level 1 of Expedition to the Barrier Peaks

In 1980, we ran every dungeon room at the same speed: The pace where players describe their movement and actions in careful detail because if they fail to look under the bed, they might overlook the coins, and if they never mention checking the door, they die in its trap.

Some dungeon masters then and a few now would say that dutifully running level 1 as a room-by-room crawl builds tension. Besides, Barrier Peaks includes wandering monsters to add excitement. Then as now, the pacing of dungeon exploration depends on players. Some enjoy a more methodical pace while others grow impatient for action. But even players who favor careful play will appreciate skipping the slow parts. After the players poke through three or four rooms full of rubbish, dungeon masters can summarize groups of similar rooms by saying they hold nothing of interest.

Even though modern adventures seldom contain sprawls of empty rooms, they often include locations best summarized. For example, Dragon of Icespire peak includes Butterskull Ranch, a 10 location manor occupied by orcs. Once my players defeated the orcs and nothing threatened them, I summarized their characters’ search of the house instead of forcing a room-by-room waste of play time. When players defeat the main threat in a dungeon and erase most of the peril, they lose patience for careful exploration. You can just summarize the loot and discoveries that remain.

Any site that merits numbered locations can mix areas that deserve different paces of play from square-by-square attention to cutting to the next scene.

As you pace the game at such a site, choose between methodical exploration and a summary based on the novelty, peril, and choices ahead of the players. When players first enter a dungeon, they face all three elements. A new dungeon starts with novelty because players know little about the threats and discoveries ahead. Even with all those empty rooms, the crashed spaceship at Barrier Peaks starts with unprecedented novelty. If a dungeon lacks peril, then its just an archaeological site; summarize the discoveries. Dungeons tend to start with key choices over marching order, light, and strategy. Does the party plan to explore carefully or rush ahead to stop the midnight ritual? Will they listen at doors or check for traps? Does someone scout?

Once these choices set a pattern and the dungeon starts to seem familiar, DMs can summarize the exploration until the situation changes.

Especially when you run a big dungeon like Barrier Peaks, you can switch your pace between methodical exploration and summary many times during a session. In the areas with nothing new to discover and no threats to face, take the shortcut of summarizing. Then when the players encounter something new, slow to a pace that lets them account for every action. “What do you want to do?”

The Movies and Stories than Inspired Dave Arneson to Invent the Dungeon Crawl

Around 1971 Dave Arneson and his circle of Minneapolis gamers invented games where players controlled individual characters who grew with experience and who could try anything because dice and a referee determined the outcomes. The group tried this style of play in various settings, but Dave invented one that proved irresistible: the dungeon.

Dave’s Blackmoor game—the campaign that spawned Dungeons & Dragons—began with a gaming group playing fictional versions of themselves in a fantasy world. The characters became champions in a series of miniature battles featuring armies clashing above ground. Without dungeons, the Blackmoor game might have stayed miniature wargaming rather than becoming D&D and a game nearly as well known as Monopoly. But by creating the dungeon crawl, Dave invented a new activity that transformed the campaign and ultimately made a lasting addition to popular culture.

The dungeons under Castle Blackmoor began as a minor diversion to the campaign’s fantasy battles above ground, but the Blackmoor bunch spent so much time underground that Arneson ultimately declared the above-ground conflicts lost to forfeit. In a recollection of that first dungeon adventure, player Greg Svenson writes, “By the end of the weekend I had fallen in love with the game.” Dave Megarry of the Blackmoor game wanted to capture the dungeon experience during Arneson’s down time, so he created the Dungeon! board game.

The dungeon crawl contributed as much to the initial popularity of D&D as roleplaying. In the dungeon, D&D brought a fun and evocative activity for a group of players. See (How the Dungeon Powered the Success of D&D and the First Role-Playing Games.

The strangest thing about focusing a game on parties of adventures who explore monster-infested dungeons for treasure is that this activity never happens in the fantasies that inspired the game. At best, you can find elements: traps and treasure in the mummy’s tomb, orcs in Moria, and so on.

The Kibri Castle Branzoll like the one owned by Dave Arneson

The Blackmoor campaign first adapted the Chainmail rules, co-written by D&D co-creator Gary Gygax. But Chainmail never mentions dungeons. At most, the rules suggest using graph paper to map efforts to tunnel under fortifications.

Dave’s Blackmoor games featured a toy castle, which served as the focus for the above-ground battles. Castles can have dungeons, although in 1971 the dungeon of popular fiction was an underground jail rather than a sprawling compound stocked with monsters and treasure.

Nonetheless, in 1972’s second issue of the campaign newsletter, the “Blackmoor Gazette and Rumormonger”, Arneson reported on dungeons below the castle where “heroes went looking for adventure and treasure.” In Playing at the World, Jon Peterson writes, “By this point, Arneson had mapped, on a pad of graph paper, a dungeon six levels deep beneath the castle, with each level containing progressively more formidable adversaries.”

How did Dave Arneson invent the dungeon crawl? By the time people started asking about it, he no longer remembered all the details. Enough clues remain to reveal the specific stories and movies that probably inspired his creation, likely during a June weekend in 1971.

The Hobbit and The Lord of the Rings offer obvious inspiration. J.R.R Tolkien imagines parties of heroes who keep finding themselves in sprawling, underground compounds.

The Hobbit takes readers into the goblin king’s warrens under the Misty Mountains, where Bilbo gets lost in the tunnels and encounters Gollum. Later, Bilbo and his party reach the abandoned dwarven city under the Lonely Mountain, where Smaug sleeps in the “great bottommost cellar or dungeon-hall of the ancient dwarves right at the Mountain’s root.” Even though the tunnels under Lonely Mountain do not fit the definition of a dungeon as an underground jail, Tolkien takes a bit of poetic license and refers to the halls as a dungeon. The Lord of the Rings revisits the dungeon again with Moria, the vast underground compound where the fellowship encounters both orcs and the demonic Balrog.

Dave cites a different inspiration for dungeons. In a 1978 interview that appeared in Wargaming issue 4, he explains. “A local TV station had on several old monster movies, which I watched while eating popcorn and reading old Conan novels. It was then that Blackmoor Dungeon was first conceived.”

Different Worlds issue 3 June/July 1979

His next account of inventing the dungeon crawl comes from his “My Life in Role Playing” article for Different Worlds issue 3, from June/July 1979. “How did it all start in Blackmoor? I can’t really say. I had spent the previous day watching about five monster movies on Creature Feature weekend (ch. 5), reading a Conan book (I cannot recall which one but I always thought they were much the same) and stuffing myself with popcorn, doodling on a piece of graph paper. I was also quite tired of my [Napoleonic] Campaign with all its rigid rules, etc., and was perhaps rebelling against it too (in fact I’m sure I was!!).”

Dave forgot the Conan book and never names the movies that sparked his imagination, but clues lead to some likely answers.

To start, the Horror Incorporated Project compiles a list of all the creature features broadcast on KSTP-TV in Saint Paul – Minneapolis throughout the 1970s.

Blackmoor started with Dave’s toy castle. “I had this neat German plastic kit and I just imagined what sort of fantasy setting it would make,” he recalled in a 2009 interview in Kobold Quarterly issue 9. Meanwhile, on Saturday May 29, 1971, The Black Room (1935) aired on the local station. The movie features a baron’s castle that, like Castle Blackmoor, sits atop a rocky hill and includes a bricked, secret room. But most revealing, the names of the movie and of Dave’s creation just swap two letters. “All this happened a few weeks before the first adventurers caught sight of [the castle].”

So Dave had a castle backdrop for fantasy miniature battles, but perhaps no dungeons yet.

Two weeks later, House of Dracula (1945) aired. This one movie might seem like five because it features all of Universal’s most famous monsters, Dracula, the Wolfman, and Frankenstein’s creation. In a remarkable piece of detective work, Daniel H. Boggs lists several similarities between the House of Dracula castle and Blackmoor. Both stand on rocky pinnacles overlooking a graveyard, a village, and the sea. Both include laboratories and torture chambers. Tunnels underneath both lead to seaside caves.

Castles with underground tunnels, monsters, and torture chambers offer much inspiration, but the Conan book surely provided even more.

While Robert E. Howard never has Conan willingly enter a dungeon, the barbarian often finds himself trapped in dungeons, forced to overcome monsters to earn freedom.

Weird Tales 1935 -The Hour of the Dragon

In “Hour of the Dragon,” Conan is imprisoned in the dungeon under the palace of King Tarascus in the Nemedian empire. A sympathetic slave girl gives Conan a rough map of the tunnels, and then warns, “Beyond these dungeons lie the pits which are the doors to Hell.” To escape, Conan defeats a monster that was one of “the goblins of Hyborian legendry, and were in reality ogres of the natural world.”

In “Rogues in the House,” Conan is lost in the pits below the house of the Red Priest, where he evades the traps that slay companions who lack Conan’s “steel-spring quickness.” Although the covered city of “Red Nails” lies above ground, its interior shares the ambiance of a dungeon.

Still, one story presents a dungeon that best resembles those in D&D. In the “Scarlet Citadel,” Conan escapes from “tunnels and dungeons” where an evil sorcerer “performed horrible experiments with beings human, bestial, and, it was whispered, demoniac, tampering blasphemously with the naked basic elements of life itself.” With a torch and sword, Conan explores a maze of tunnels while overcoming monsters.

In 1971, Dave Arneson started with a toy castle, a location inspired by creature features,  and the notion that something might lurk underneath. “[The model] was too small for the scale I wanted,” Dave said. “But it was a neat kit and I didn’t want to abandon it, so the only way to go was down [into the dungeons].”

He added a treasure hunt from Tolkien, traps from Robert E. Howard, lurking monsters from both authors—and perhaps from some creature features—to invent a new activity for the characters in his Blackmoor campaign. When Gary Gygax played one of Dave’s Blackmoor games, the experience so fired Gary’s imagination that he went on to flesh out the game that would become Dungeons & Dragons. In the process, Gary’s imagination and broad knowledge of sword and sorcery would add countless details inseparable from the game. Ultimately, the dungeon crawl proved so compelling that it took root in popular culture.

To Run a Great Dungeon, Write All Over the Map

For running a dungeon, the familiar map with numbers sets dungeon masters up for trouble. Many times when characters enter a dungeon room, I turn to a room’s key, and then learn that the party just passed a trapped door. “Wait! You can’t go in yet because…no particular reason.” Other times, when dungeon expeditions recklessly make noise, I want to find any monsters that hear. After all, dungeons should feel like active places where dangers lurk and where actions bring consequences. I check the map, spot 10 or so nearby room numbers, and realize that paging through the adventure text would stall the game for minutes. So I wind up supposing the werebats next door failed to hear the thunderwave. I guess monsters can wear headphones. Meanwhile, a dog in the yard hears a bag of chips opening in the attic.

Really, as a tool for running a dungeon, the typical map with just numbered locations sucks. But DMs can easily improve maps and the process leaves you better prepared for adventure.

Annotated dungeon map for CORE 2-1

My best tip for running a great dungeon: Write all over the map.

This tradition of minimally-useful maps dates to the publication of Palace of the Vampire Queen and F’Chelrak’s Tomb. For 40-some years published adventures almost always include maps that suck. Designers should stop following a bad example. For a better example of useful dungeon maps, look to entries in the one-page-dungeon contest.

Meanwhile, few DMs considered improving their maps by marking up a brand new copy of, say, G1 Steading of the Hill Giant Chief. In 1978 its $4.49 price amounted to $18 today. You couldn’t even mark a copy of the maps, which TSR printed in blue to thwart Xerox.

For published adventures, make a copy of dungeon map pages. For your own maps, either write on your original or save a clean copy. Then get out your colored pens and highlighters and mark the maps with the notes you need to run.

  • List monsters in their locations.
  • Mark traps and locked doors.
  • Circle areas where characters may hear or smell things in the dungeon like waterfalls, forges, unholy rituals, and so on.
  • If guards might call for reinforcements, mark the travel times between key locations.
  • Circle areas controlled by factions.

Time spent writing on the map doubles as preparation for running the adventure. If you mark enough, you can run direcly from the map.

D&D’s Advice for Dungeon Masters Offers Nothing on Running Dungeons

Even as a game with dungeons in the title, Dungeons & Dragons offers zero advice for dungeon masters aiming to run dungeons. The game provides plenty of help for the solo fun of sitting with a blank sheet of graph paper and designing dungeons, but nothing for sitting behind a DM screen across from players entering the underworld.

Seeking to fill this gap, I paged through a stack of guides and volumes of advice, many with titles like Dungeonscape and even just Dungeons. The dungeon-related content breaks down like this:

65% designing dungeons
35% exploring dungeons
0% running dungeons

To be fair, the 0% appears because I never counted D&D’s original volume 3, Underworld & Wilderness Adventures. That book includes Gary Gygax’s attempt to describe dungeon crawls in terms familiar to miniature-wargame grognards. So the explanation has parties taking turns marking inches of movement. Today, only groups seeking D&D’s roots attempt such formality.

Why so few tips for running the dungeon part of a dungeon adventure?

Partly, we givers of advice tend to suppose that dungeon masters already know how to master dungeons. After all, the game’s 3-step loop works underground. (1) Describe the situation. (2) Ask what the players want to do. (3) Resolve the action. Newcomers easily learn these 3 steps at the heart of roleplaying games, becoming players and potentially DMs. Beyond that, most advice for game masters works perfectly well underground.

Also, dungeon advice can prove situational. That original procedure with turns and movement works fine in a mythic underworld, but in other locations it amounts to tedium.

Still, when I started writing tips for running dungeons, and then asked for help from D&D fans on Twitter, I uncovered plenty of help specific to running secrets and challenges mapped on a sheet of graph paper. In a follow-up post, I reveal my favorite tip.

Dungeon Masters: Just a Little Attention to Darkness Pays Off

My favorite sightseeing stops include caves and inactive mines. Cave tours inevitably include tales of the cave’s original explorers. I imagine myself in their place, delving by a feeble glow from a lantern, discovering underground landscapes and traces of people and creatures long gone, and I relish the feelings of wonder and mystery. My love of dungeons seems inevitable. In sprawling undergrounds, even modern lights don’t reach far before darkness engulfs their glow. I gaze into midnight shafts and feel a shiver much like leaning over a rail on the 95th floor. These tours always pause to extinguish all the lights and give a taste of complete darkness, but not before making sure no one feels close to panic. Like heights, spiders, and snakes, darkness triggers a primal fear that we share.

As played by most groups, the Dungeons & Dragons rules for light work like this: When the party starts their descent into darkness, the dungeon master asks what they have for light. Perhaps everyone has darkvision and that’s that. More likely, the group includes a human, so someone fires a torch or casts light and then no one pays attention to the subject until the next dungeon.

Through most of my experience as a DM, I played that way. The same goes for the multitude of DMs I’ve played with. After all, the rules as written make careful attention to light seem like a chore. How can anyone be expected to keep track of who carries a light and how that glow interacts with the senses and positions of various characters? You need a computer for that. My scrapheap of article-ideas-never-written includes a post describing light as a thing everyone ignores because it never adds fun. Everyone would have ignored that post too.

Surely tense dungeon-survival sessions can bring fun. In those campaigns, parties struggle to escape the dungeon with their loot before their supplies of torches and oil run out. But most D&D players favor heroism over such grit. Besides, D&D gives so many characters darkvision that calling out the stumbling humans and halflings seems pointless.

I’ve changed. When I run dungeons now, I pay some attention to light without getting mired in detail. The benefits of a little consideration surprised me.

As a party explores a dark space, I pay attention to just one thing: about how far they can see past their front row. For most groups, that’s 60-feet from the character with darkvision closest to the lead. And then when I describe, I mention what they can’t see because of the cover of darkness. When possible, I describe any sounds that come from that shrouded space. Imagine the scratches, the whispered malevolent voices, the creak of doors, the drip of water. Sometimes perceptive characters see glowing eyes that suddenly wink out in the depths. If the party recklessly chases ahead into the unseen, they deserve the panicked moment when monsters close from every direction. When I draw maps as players explore, my lines for the walls end where the darkness starts.

That small regard pays off with a sense of tension, atmosphere, and mystery.

In cramped dungeon rooms, light hardly matters, but in long corridors, underground cathedrals, vaulting caverns darkness easily swallows the feeble glow of a lantern. Darkvision only makes 60 feet seem like dim light. Beyond that who knows what spies the party’s glow and clamor?

5 Reasons Most D&D Players Stopped Exploring Megadungeons

Dungeons & Dragons creators Dave Arneson and Gary Gygax built their campaigns around huge dungeons that grew and changed. Megadungeons span enough rooms and levels to become the focus of an entire campaign without ever being fully explored. These megadungeons enabled Dave and Gary to run campaigns for dozens of players. On any day, they could host games for whoever happened to show up for a session. (See When Megadungeons Ruled Dungeons & Dragons.)

Even though the megadungeons under Greyhawk and Blackmoor became the foundation of Dungeons & Dragons, such dungeons rarely see play anymore. Why not?

1. Players never saw any examples. Originally, Gary thought that players would never pay for published dungeons. After all, players could easily make up their own. Despite this belief, TSR distributed the first published dungeon, Palace of the Vampire Queen. Strong sales proved Gary wrong, and so he set to publish his own dungeons. (See 9 facts about D&D’s first standalone adventure, Palace of the Vampire Queen.)

But Gary’s megadungeon under Greyhawk Castle seemed impossible to capture in writing. As adventurers explored and plundered, the dungeon changed constantly. New monsters wandered in to take empty rooms. Whenever the players’ attention turned, the layouts of old levels subtly changed. Entire new levels appeared. Most of the content lay in one-line descriptions, or worse, locked in the heads of Gary Gygax and co-dungeon master Rob Kuntz. Decades later, Gary wrote, “If we handed over the binders containing the maps and the notes, I don’t think even the ablest of DMs would feel empowered to direct adventures using the materials.”

So rather than attempting to capture Greyhawk Castle, Gary opted to publish adventures that he had created for D&D tournaments at conventions. For instance, the official D&D tournament at Origins ’78 ran the G1-3 adventures. The choice to publish such adventures changed the development of the game. D&D players everywhere saw Gary’s published adventures as a model. Instead of patterning their games after a megadungeon like the one Gary played at home, players imitated adventures created for a few hours of competition.

In 1990, TSR finally published WGR1 Greyhawk Ruins, its first megadungeon in print. “There are more than two dozen levels of horror and treasures. Run into brutal foes and gain uncountable wealth-nearly 1,000 separate room descriptions in all!” Gary had left TSR five years earlier, so fans hoping to explore his actual creation felt disappointed. James M. Ward and other veterans of the Grayhawk campaign still at TSR gave insights, but the dungeon even lacked the Great Stone Face Enigma of Grayhawk that Gary himself drew for the first D&D supplement.

The Ruins of Undermountain followed 7 months later. Undermountain appeared in a box with maps and with booklets that sketched out encounter areas. This outline mirrored the terse descriptions and evolving notes that Gary Gygax used for Greyhawk Castle, but the sketch failed to satisfy DMs accustomed to publications ready for play.

Perhaps locking a megadungeon in a book kills it. Printed pages cannot capture the dynamic essence of those original levels.

2. The ecology and rational of megadungeons seemed ridiculous. From they start, players struggled with the logic of megadungeons. Where did all those monsters get their food or leave their waste? Where did the creatures and treasure come from? Every dungeon master invented an insane wizard as an architect for their game’s underground sprawl until the notion became trite.

In the little, brown books, Gary suggested dungeons with layouts that always changed and grew to “maintain freshness,” but that made the megadungeon even more implausible.

Then Gary published adventures that featured a logic sometimes called Gygaxian naturalism. Monsters had lives of their own that involved feasting, scheming, sleeping, and everything but waiting for heroes to come kill them. Rather than wandering monsters living in defiance of reason, we saw giants and drow in their steadings and vaults. For many players, the giant- and drow-series adventures set an example that killed the megadungeon.

Soon, any DM peddling a megadungeon had some explaining to do. For instance, The Ruins of Undermountain kept to the insane wizard trope, then added magic that continuously gated in fresh monsters from across the Realms, and deep entrances that allowed creatures from the Underdark to well up.

3. Play styles expanded. Sometime in the middle of the 70s, for the first time ever, a party of adventurers visiting the inn met a hooded stranger with a job that needed doing. D&D expanded beyond a series of dungeon expeditions aimed at claiming treasure. Players began to favor games that mixed action with story. Waterdeep: Dungeon of the Mad Mage rates as my favorite megadungeon in print, but when I ran it, the group longed for a story and for motivations beyond a hunger for treasure.

4. Megadungons can feel monotonous. Even the biggest megadungeon only shows a tiny corner of the giant canvas that D&D worlds can offer. In a campaign limited to a single dungeon, kicking in endless doors to fight and loot can start fresh and thrilling but often becomes a tiresome slog. Even those of us who like dungeon crawls want to see some daylight and a plot.

5. Computers do megadungeons better. In 1979, computer games like Akalabeth and Temple of Apshai took gamers into megadungeons and started an electronic-gaming genre. Dungeon crawls limit players’ options, so they offer an easy premise for a computer game. (See How the Dungeon Powered the Success of D&D and the First Role-Playing Games.) With a computer DM, players can explore anytime. Digital dungeons offer faster play and better graphics. For players who just want to visit a sprawling underworld to kill monsters and take their stuff, electronic games probably offer a better experience.

Can a megadungeon work today?

A clever design can avoid the problems that pushed megadungeons out of play.

A story-centered game can take PCs into a megadungeon to accomplish more than looting. For instance, when Monte Cook created his superdungeon The Banewarrens, he paired it with overarching plot. Players don’t raid the Banewarrens just to loot. Instead, the story leads to objectives that require missions into the place.

Many megadungeons avoid monotony by introducing levels or zones centered on unique themes such as crypts, flooded sections, or fungus gardens. Even the levels under Castle Greyhawk followed themes that grew more exotic at deeper levels.

A megadungeon design can add intrigue and roleplaying by borrowing a page from The Keep on the Borderlands and adding factions of monsters. Players can join a side or play one against another. Factions under attack will bring reinforcements, creating more interesting battles, and giving players a reason for caution. The stories “Red Nails” by Robert E. Howard and “The Lords of Quarmall” by Fritz Leiber helped inspire the concept of dungeon exploring. Both yarns centered on feuds and intrigue.

A megadungeon (and a live DM) can create player agency and tests of ingenuity that no computer can match.

Although good design can yield a megadungeon that proves fun to play, ordinary dungeons can bring the same advantages. Today’s gamers tend to create megadungeons to foster nostalgia or to enable episodic play.

When Megadungeons Ruled Dungeons & Dragons

In the early 70s, as Gary Gygax co-created Dungeons & Dragons, he played the game seven times a week. He wrote, “As I worked at home, I did not schedule play sessions, but when a gamer or two dropped in on a day, I made haste to finish immediate work and put on my DM’s hat. Evening games with the regulars were generally scheduled a few hours or a day or two ahead.” Weekend games included 10 to 20 players.

How did Gary referee his ongoing Greyhawk campaign for a cast of characters that changed completely from session to session? (Nowadays, dungeon masters like me stretch to keep one or two absent PCs from upsetting our game’s plot.) How did Gary create material for so many games? (I always scramble to prepare one game a week.) In 1974, as Gary focused on publishing D&D, he began sharing campaign duties with a second referee, Rob Kuntz. (I would never dare attempt collaborating on a campaign with a second dungeon master.)

The secret to all these feats lay in the design of the 12+ level megadungeon under Greyhawk Castle.

Level 1 of the dungeon under Castle Greyhawk

Like Gary, D&D co-designer Dave Arneson ran a campaign for a large and fluctuating pool of players. Dave managed with his own megadungeon below Blackmoor Castle.

Every game session mounted a new expedition into the dungeon, so the particular cast of characters never mattered. These megadungeons enabled a style of episodic play that made those original campaigns manageable. Al from Beyond the Black Gate described the advantage well. “The scale and scope of the Megadungeon makes it friendlier to episodic play than for the more common ‘clear the dungeon’ style of play. The Megadungeon is the perfect place for short, engaging adventures in a compelling environment (even if those sessions just happen to combine into one long campaign).”

Gary never needed to adjust a session’s difficulty to party size or experience, because players could chose a difficulty by choosing how deep to delve. The game awarded more gold and experience to players who dared the lower levels. See “Why D&D characters get tons of gold and nowhere to spend it.”

Today, we tout the value of sandbox play, where players can take the game in any direction they want without feeling corralled by some story in the DM’s head. DMs tend to expect sandbox play to require improvisation and in-game adjustments. For instance, the designers worked to make much of the Princes of the Apocalypse adventure play as a sandbox. When I talked to dungeon masters about running it, we always focused on the challenges of preventing the PCs from straying into certain death.

The megadungeon let Dave and Gary to act as referees rather than dungeon masters—that term would not see print until the game’s second supplement Blackmoor in 1975. They could run a game entirely from notes, wandering monster tables, and the whims of the dice. If megadungeon referees choose, their campaigns never needed improvisation or in-game meddling. This gives players more control over their characters’ fate—more player agency—than in typical modern games.

Gary kept preparation manageable. He wrote, “I usually made one-line notes for my dungeon encounters, from around 20 to 25 of same for a typical level done on four-lines-to-the inch graph paper—a few more on five-, six-, or seldom used 8-line graph paper. The other spaces were empty save for perhaps a few traps or transporter areas and the like.” He and Rob Kuntz kept notes. “When the encounter was eliminated I simply drew a line through it, and the place was empty for the foreseeable future. I’d give Rob the details of any session he was not at and vice versa, so we winged all of [the campaign management]. Sometimes a map change and encounter key note of something special in nature was made, but not often.”

On page 4 of the original, brown book, The Underworld & Wilderness Adventures, Gary made a megadungeon a requirement for play. “A good dungeon will have no less than a dozen levels down, with offshoot levels in addition, and new levels under construction so that players will never grow tired of it. There is no real limit to the number of levels, nor is there any restriction on their size (other than the size of graph paper available). ‘Greyhawk Castle,’ for example, has over a dozen levels in succession downwards, more than that number branching from these, and not less than two new levels under construction at any given time. These levels contain such things as a museum from another age, an underground lake, a series of caverns filled with giant fungi, a bowling alley for 20’ high Giants, an arena of evil, crypts, and so on.”

The Doomvault from Dead in Thay

The Doomvault from Dead in Thay

Although folks don’t play megadungeons much now, the places remain uniquely suited to episodic play with multiple parties exploring the same space. Scott Fitzgerald Gray ingeniously used those strengths when he wrote the adventure Dead in Thay for a D&D Encounters season. The Encounters program lets players drop in a game store for a night of D&D. Different players may come for any night of play, shuffling each table’s adventuring party.

At first, the program managed these fluctuations by requiring every table to play the same episode in the adventure. The format limited players’ choices to battle tactics.

In Dead in Thay, each table launches their own, unique foray into a megadungeon called the Doomvault. By creating the sort of dungeon that made the Greyhawk and Blackmoor campaigns work, the season rediscovered some of the format’s advantages: episodic play for whoever attends, the freedom of a sandbox where players can change the environment, and manageable cooperation between dungeon masters.

When Shannon Appelcline looked back on the adventure, he wrote, “For the most part, Dead in Thay is a classic, old-school dungeon crawl of the sort you could find back in the ‘70s. However, it presents a more mature, more active dungeon, where the rulers of the realm can react to the players’ actions…and where the players themselves could change an environment.”

Gary Gygax’s Dungeon Building Spells (and the Ones He Should Have Made)

Since 1975, every single player of a wizard or magic user has read the Magic Mouth spell, and then chosen to skip it. Prove me wrong.* Who wants to use a 2nd-level spell to put a message on a wall when a piece of chalk works as well? While Magic Mouth never gets used by players, Glyph of Warding only ever gets misused. Recently, I saw a player use glyphs to manufacture explosive arrows. He overlooked the sentence that says that a glyph breaks if it moves more than 10 feet. That limitation exists now because players of earlier editions dreamed up the same stunt. Without the exploit, no player prepares glyph. Judging from the spell lists in the Monster Manual and Volo’s Guide to Monsters, non-player characters shun these spells too.

Why does the Player’s Handbook include spells that players virtually never use? Part of the appeal of these spells comes from nostalgia. Both date from the 70s. Mainly though, the spells appeal to the game’s dungeon architects and dungeon masters. For example, magic mouths and glyphs of warding appear in at least three of the Dungeons & Dragons hardcover adventures.

Compared to chalk, Magic Mouth offers more portentous way to deliver a message. Glyph of Warding adds a common magical trap. The spells weave useful magical effects into both the lore and the rules of the game. They give DMs ready-made tricks for their dungeons. Players enjoy recognizing these familiar bits of spellcraft mixed with the fantastic.

The game’s original Players Handbook includes even more spells aimed at dungeon architects instead of players.

At level 5, Distance Distortion made a corridor appear either twice as long or half as long as its actual length. D&D’s co-creator Gary Gygax loved to confound dungeon mappers. I imagine a party of lost players at Gary’s table, growing sore, and insisting that Gary described something wrong. Gary laughs slyly, opens the Player’s Handbook, and points to page 80.

At level 6, Permanent Illusion appealed to a few players, but dungeon masters gained a way to trick or terrify characters and to disguise pits. The spell evolved into fifth edition’s Programmed Illusion.

At level 8, Glassteel made glass or crystal as strong as steel. A few players dreamed of transparent weapons and armor, but I suspect Gary Gygax mostly sought a way to add durable windows to his tricky dungeon rooms. Between the scientific flavor of a name torn from sci-fi and they way walls of force did the same job better, dungeon builders never embraced glassteel.

To last, a few of these dungeon builder spells needed the help of the 8th-level Permanency spell. In fifth edition, Magic Mouth lasts until dispelled, but originally that same duration required an 8th-level spell and a lost point of Constitution. If I were a mad mage building a dungeon, I would opt for painted signs instead.

Permanency helped dungeon architects extend spells like Wall of Fire, Gust of Wind, Wall of Force, and many others. Edition 3.5 featured the best realization of Permanency.

As I look back on the spells for dungeon makers, I see a missed opportunity. D&D could benefit from more spells that filled gaps in the toolkit of Keraptis, Halaster, Galap-Dreidel, and all the game’s other dungeon builders.

The architect of the Tomb of Horrors, Acererak, creates dungeons to trap the souls of heroes, but he faces a problem: Before adventurers die, they keep wrecking stuff. In Return to the Tomb of Horrors and Tomb of Annihilation, Acererak recruits unliving maintenance crews to repair damage for the next party of doomed adventurers arrives. Now imagine an infomercial featuring an exasperated archlich saying, “There has to be a better way!”


Spirit of Remaking

6th-level transmutation
Casting Time: 1 hour
Range: Touch
Components: V,S,M (a jewelled hammer worth 500 gp, which the spell consumes)
Duration: Until Dispelled
Save: None

You touch an object or section of construction of large size or smaller. If the target suffers damage, the spell repairs the damage. If the target includes mechanisms, the spell returns these mechanisms to their original state. So for example, traps can be reset.

This spell repairs at the pace of a skilled laborer. The spell will not function while its target is observed.


In Tomb of Annihilation, Acererak uses adamantine parts held together with Soverign Glue to prevent adventurers from breaking his magical puzzles and traps rather than engaging with them. Can you imagine the building expense? Every dungeon builder needs some way to keep adventurers from simply cutting the Gordian Knot.


Ward of Sequestration

6th-level abjuration
Casting Time: 1 hour
Range: Touch
Components: V,S,M (a powder composed of diamond, emerald, ruby, and sapphire dust worth at least 500 gp, which the spell consumes)
Duration: Until Dispelled

You cause a Large-sized or smaller object to be warded so that if it’s damaged or manipulated in certain ways, then it vanishes to an extra-dimensional space, safe from harm. You set the ways that manipulating the object will cause it to disappear. Also, you can set how long the object will remain in the extra-dimensional space. For example, it could remain sequestered just a minute or 1,000 years. If the object is built into a larger construction such as a wall or door, then when the target disappears, it’s replaced with stone, metal, or similar materials that blend with the surrounding construction. If the replacement materials are removed from the construction, then they disintegrate.


In the early days of D&D, many DMs suffered a common embarrassment: Players would dare to enter some dungeon sealed for millenia, and find it stocked with living creatures who somehow survived the ages in their monster hotel rooms. Some smart-assed player would start asking quetions, and soon the whole group starts mocking the absurdity of the DM’s creation.

To avoid ridicule, DMs learned to fill their vaults with undead, constructs, and elementals, but that leaves so many fine monsters unavailable.


Temporal Prison

8th-level transmutation
Casting Time: 1 action
Range/Area: 60 ft (20 ft)
Components: V,S,M (an hourglass)
Duration: Until Dispelled or Triggered
Save: None

You attempt to imprison creatures in spaces where time slows to a near standstill. Creatures within 20 feet of a point you choose within range are affected in ascending order of their current hit points. The spell affects up to 175 total hit points. Subtract each creature’s hit points from the total before moving on to the creature with the next lowest hit points. A creature’s hit points must be equal to or less than the remaining total for that creature to be affected.

Inside a temporal prison, a blink of an eye can take hours. This slowing of time means that imprisoned creatures do not grow older and their body functions virtually cease. These prisons take a crystaline shape that envelops each creature. To the touch, the prisons feel solid and glassy. Bright light that passes through the prisons appears dim and dim light cannot penetrate. The prisons provide total cover to the creatures inside. Moving the prisons by any means other than teleportation breaks the spell

You can decide on triggers that cause the spell to end. The condition can be anything you choose, but it must occur or be visible within 120 feet of the target. The most common trigger is approaching within a certain distance. You can further refine the trigger so the spell ends only under certain circumstances or according to physical characteristics (such as height or weight), creature kind (for example, the ward could be set to affect aberrations or drow), or alignment. You can also set conditions for creatures that don’t end the spell, such as those who say a certain password.

At Higher Levels. When you cast this spell using a spell slot of 9th level, add an additional 75 hit points to the total number of hit points affected.


*My friend John P. Jones plays a character who casts Magic Mouth on his arrows so they deliver a mix of messages and terrified screams when they hit. John plays a bard and you know how they are. My outrageous generalizations about wizard players stands. John’s trick works because Magic Mouth now lasts until dispelled. John can prepare arrows in advance and still adventure with all his spell slots.

The Dungeons & Dragons spells Gary Gygax never meant for players

4 Pop-Culture Assumptions That Dungeons & Dragons Destroyed

The media keeps telling us how we, the geeks, have won popular culture. A show with dragons became prestige television, and networks keep aiming to produce  the next Game of Thrones. A minister I know boasted that she was a member of her high school Dungeons & Dragons club. The Return of the King won best picture. Fan culture is everywhere. So we forget that in the early days, when D&D burgeoned by word-of-mouth, no one had seen anything like it.

Of course, little in D&D stands as completely new, but in the 70s, unless you joined a tiny cult of miniature gamers interested in fantasy, the game defied understanding. Unless you followed a few, obscure genre authors, you would never have seen anything like it. You shared popular assumptions that D&D would explode.

1. Fantasy is for children and a few oddballs.

Forget the The Lord of the Rings, and then name a work of fantasy that was widely known before D&D. Anything you name is a fairy tale or fable—something for children. Conan? He’s a comic book character. Every grown up knows comics are for children. Now consider The Lord of the Rings. It enjoyed enough popularity to get cited by Led Zeppelin and some other long hairs, but when Hollywood tried to trade on its popularity, they added musical numbers. Hollywood did not think they could reach a big enough audience of oddballs, so they adapted for children.

In making the 1978 movie Superman, the producers needed adults to see a movie about what they saw as a children’s character. Imagine marketing a Thomas the Tank Engine film to adults. To free grown ups from the embarrassment of buying tickets, they gave a fortune to Important Actor Marlon Brando. For 15 minutes of screen time, Brando received $3.7 million up front, plus 11.75% of the film’s take, right off the top. The film’s marketing rested heavily on the actor’s performance. All so grown ups could gain an excuse to see the movie on date night.

As a kid in the 70s, All the fantasy I knew came from picture books. Stories where trolls lived under bridges and bugbears under beds. Nothing prepared me for a game inspired by Appendix N. A game where trolls lived in dungeons and refused to die. The original Monster Manual revealed beholders, mind flayers, chromatic dragons and countless other dreadful wonders that filled me with excitement.

The public’s unfamiliarity with fantasy contributed to the panic that surrounded D&D in the 80s. God fearing adults saw their teenagers obsessed with spells and children’s fairy tale nonsense, but darker and more violent. They settled on the only logical explanation, demon worship, because the culprit could not possibly be a really fun game.

Meanwhile, I worked to find the books named in The Dragon’s Giants in the Earth column and later in Appendix N. I found none. Admittedly, I suffered the disadvantage of shopping from a mall bookstore. I knew nothing of used book stores or inter-library loan. Nonetheless, few of Gary Gygax’s inspirations remained in print. Today, fantasy books of all stripes crowd the shelves. Then, I took years to collect the books that inspired the game.

2. Games are terrible.

In the 70s, games sold as toys and they were all terrible. They suffered from stupid, and random mechanics: Roll a die and move that many spaces. The winner becomes obvious long before the end, yet they took forever to finish. Games covered prosaic subjects like Life and Payday, or financial wish-fulfillment like Monopoly or, well, Payday. Still, I liked games enough that I even played terrible ones endlessly. (Except, of course, for Monopoly, which I suspect Hasbro makes to convince millions that games are tedious. I cannot fathom their plot’s endgame.) My standards were so low that I liked the 1974 game Prize Property where you launched legal actions against your opponents to stall their building developments. Legal actions. The box claimed fun for ages 9 and up.

People suffered from narrow ideas about what a game could be. Someone wins, someone loses, the game never extends past the board and never continues after you close the box.

Before I saw D&D, I sat with a sheet of graph paper and tried to imagine how the game would play. Working from a 12-year-old’s lunch-room pitch, I got nowhere. From my experience rolling a die and moving that many squares, I had no clue how a game could allow the things the kids claimed.

Dungeons & Dragons Basic SetSo in a mere 48 pages, the Holmes Basic D&D rule book shattered my notion of what a game could be.

Later, when I described the new game, everyone asked the same questions: “How do you win?” and then, “if you can’t win, what’s the point?” Everyone struggled to grasp the notion that you played to have fun without any chance of winning. For more, see But how do you win?

3. Only young children should roleplay.

People sometimes say that D&D did not invent the roleplaying game. Kids have always roleplayed; we just called it make believe. By spreading roleplaying beyond the playground, D&D alarmed parents, ministers, and other responsible adults.

When D&D first reached mainstream attention, reporters painted the game as a “bizarre” activity enjoyed by “secretive” and “cultish” players.  Parents feared that playing a role in D&D would lead their children to confuse fantasy with reality. After all, wasn’t anyone old enough for such a complicated game too old for make believe? Kids talked about being a wizard or a thief and folks worried that kids believed it. See The Media Furor that Introduced the “Bizarre Intellectual Game” of Dungeons & Dragons to America.

D&D’s revolution went beyond make believe. Much of the appeal came from playing a character with stats that carried to the next session, and from the idea that characters gained experience and improved. In Playing at the World, while describing D&D’s reception, Jon Peterson shows new players and reviewers always touting the experience system. The steady reward of experience and levels forged an obsession for many players. The combination proved so compelling that just about every computer role-playing game borrows it.

4. Dungeons are just medieval jails.

Zombies and vampires appear everywhere in popular culture. Both archetypes seem medieval, but the popular conception of zombies only dates back to George Romero’s 1968 movie Night of the Living Dead.

The concept of a dungeon as an underground sprawl with monsters and treasures, is even newer.

In the fantasies that inspired the game, no character explores a sprawling dungeon. At best, you can find elements of the dungeon crawl, such as treasure in the mummy’s tomb, orcs in Moria, traps and underground cities in a Conan yarn, and so on. Forget Indiana Jones; he came later.

Now, the dungeon adventure qualifies as a trope that appears in virtually every computer fantasy game.

In my world before D&D, games gave the fun of launching legal action against fellow real estate developers. When I opened the basic rules, I could brave the peril and mystery of the dungeon shown in the Stone Mountain cross section. Still today, no image inspires my enthusiasm to play as much. I jumped from property law to Greyhawk.

For more, see How the Dungeon Powered the Success of D&D and the First Role-Playing Games.

By the end of the 70s, fandom had yet to dominate popular culture, but Star Wars and Superman and Dungeons & Dragons had established a beachhead. The gains would only continue.

For me, the 48 pages of the 1977 Basic Set did more than introduce the best game in the world, those pages turned some of what I understood upside down.
