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

The Obvious Innovation in Fifth-edition Dungeons & Dragons That No Designer Saw Before

Stirrups. Zero. Shipping containers. Luggage with wheels. All these innovations seem obvious in hindsight. But they went undiscovered for millennia, until someone’s bright idea changed the world—or at least put airport porters out of work. Even those hotel shower rods that curve made someone rich.

Fifth edition Dungeons & Dragons includes one obvious-in-hindsight innovation that the game’s past designers failed to spot. Alas, it won’t make anyone rich.

Sverrir by ArboUp until fourth edition, D&D fighters gained extra attacks, but fourth edition avoided them. The designers shunned extra attacks partly to speed play by reducing the number of attack and damage rolls. Sure, spells attacked lots of targets, but at least spells only required one damage roll.

Also fourth edition, like all earlier editions of D&D, aimed to parcel out benefits smoothly as characters leveled up. In theory, this made the difference in power between, a 4th- and 5th-level character about the same as the difference between levels 5 and 6. Characters at similar levels could adventure together without someone routinely dealing twice as much damage. But a second attack on every turn brings a fighter a big jump in power.

The designers of past editions worked to smooth these jumps in power by granting fighters something less than a full extra attack. AD&D gave fighters extra half attacks, and a need to remember half attacks. Third edition traded half attacks and the memory issue for weaker attacks and fiddly attack penalties. These solutions complicated the game with awkward memory demands and calculations.

So playtest versions of fifth edition did not grant fighters and other martial characters an Extra Attack feature. Rather than gaining more attacks, these classes earned features that enabled attacks to deal more damage. But this approach put fighters at a disadvantage against weaker foes easily dropped by a single blow.

When a fighter confronts a goblin horde and only makes one attack per turn, no amount of extra damage matters because one strike can only fell one goblin per turn. To help martial types against weak foes, the playtest included cleaving-attack powers that swept through groups. But such features failed to remedy another trouble: To-hit bonuses in fifth-edition increase at a slower rate and never grow as big as in earlier editions. The designers call this bounded accuracy, because they do not come from marketing. Bounded accuracy means that fighters hit weaker foes less easily than in past editions.

Fighter types should hew through the rabble like grass until, bloodied and battle worn, they stand triumphant. But in the playtest, even the mightiest spent turns muffing their one attack against some mook. With an extra attack, misses matter less because there’s more where that came from.

During the playtest, I wrote, “If D&D Next’s designers can find a good way to allow fighters to gain multiple attacks against weaker opponents, then a key piece of the Next design puzzle falls into place.”

Late in fifth edition’s creation, the designers compared the benefits each class gained as they leveled and noticed that wizards leap in power at 5th and at 11th levels. These jumps come from quirks of a spell list that date to the beginning of the game. At 5th level, wizards gain potent attack spells like Fireball, plus unbalancing buffs like Haste. At 11th level, wizards gain 6th-level spells, which bring save-or-die effects like Disintegrate. At the 9th spell level, Gary Gygax felt comfortable stashing world-altering spells like Wish and Time Stop, because his players never reached 17th level and never gained easy access to them.

Earlier editions of D&D aimed to parcel out benefits smoothly as characters leveled up. Those editions’ designers ignored the leaps in power certain spells brought; the fifth-edition designers embraced the leaps.

This brought the obvious-in-hindsight innovation: Rather than offering fighters half attacks or fiddly attack penalties, fifth edition matches the leaps in power brought by additional attacks to the leaps brought by 3rd, 6th, and 9th-level spells. Fighters gain extra attacks as wizards gain these spells. At the same levels, other classes gain potent powers and spells of their own. For instance, the bard’s Hypnotic Pattern spell got a fifth-edition redesign that moves it to 3rd level and dramatically increases the spell’s power. 

Third and fourth editions arbitrarily aligned the game’s tiers with 10th and 20th levels, because of round numbers. The fifth-edition tiers match to the levels where characters gain the best new powers and spells. These leaps in ability mean 4th- and 5th-level characters cannot adventure together without displaying big power differences, but characters in the same tier can join a party and contribute.

It all seems obvious now. Designer Mike Mearls says that a lot of innovations in game design work that way.

13 of the Craziest Quirks in the Dungeons & Dragons Rules

Eventually, everyone who plays Dungeons & Dragons finds a place where rules seem to defy logic and common sense. These quirks tend to stem from three good reasons:

  • The D&D rules don’t attempt to cover every situation. Few players would want to grapple with so many rules, so the design brings a more compact set of rules that apply to most of what happens in a game. To make sense of unusual situations and corner cases, D&D relies on the judgement of dungeon masters.

  • Rarely, the designers wrote rules that failed to work as intended. Often when the rules as written serve well enough, the D&D team chooses not to tamper with the text.

  • The D&D rules accommodate a legacy of earlier editions spanning 40-some years of history.

I asked D&D enthusiasts to name the strangest quirks in the rules. This post lists some of the best answers. I skipped the part of D&D that most brazenly defies reality: The rules for damage and recovery. Those unrealistic hit points enable the games’ combat-intensive, dungeon-bashing style, so I count that absurdity as a feature. (See Why Gary Gygax Added Unrealistic Hit Points to D&D.) To learn to love hit points, just avoid asking questions. For example, I wish I could stop wondering how (#13) one healing potion completely cures a new adventurer while a legendary hero needs to guzzle 20 for a similar recovery.

12. Characters with the Lucky feat can close their eyes, swing blindly at a foe, and gain a better chance of hitting than they would get from attacking as normal. When you use Lucky, you roll an extra d20 and choose your attack roll from any of the d20s you rolled. When you roll at disadvantage, you roll two d20s. So Lucky lets you choose your best roll from any of the three dice: the two dice rolled for disadvantage and the one for lucky. Use the force, indeed!

11. In one round, someone who flees a Wall of Fire, and then gets forced back in on another character’s turn takes more damage than someone who just stayed in the flames through the entire round. (See D&D’s Inconspicuous Phrases That You Notice Once You Master the Rules.)

10. Archers shooting blindly into impenetrable fog hit as easily as they do when they see their targets. A blinded attacker suffers disadvantage and typically gains advantage because their target can’t see the strikes to defend. Advantage and disadvantage cancel, so the attacks roll as normal. This makes some sense for melee attackers flailing in the dark. For someone shooting blindly, the lack of a to-hit penalty flouts common sense.

9. Daylight fails to generate sunlight. Daylight originated from the first-edition spell Continual Light. Back then, every new D&D player counted themselves as the first to realize a 2nd-level spell enabled them to easily destroy vampires! They were wrong. Then, as now, you don’t become a D&D designer without being pedantic enough to rule that light “as bright as full daylight” falls short of “direct sunlight.”

8. The Chill Touch cantrip isn’t a touch spell and doesn’t deal cold damage. In past editions, the spell really had a range of touch, but even then, its damage came from negative energy, the necromantic damage of the era.

7. Faerie Fire doesn’t deal fire damage or involve fairies. The spell references naturally glowing fungus.

6. Detect Evil and Good doesn’t detect evil and good. The spell’s name comes from past editions when it worked as described. Back then, too many players took shortcuts through adventures by detecting for evil and murdering potential villains in the first scene. Now the spell detects the creature types that are supernatural representatives of good and evil.

5. Only crossbow experts and sharpshooters can attack with a net without suffering disadvantage. Nets are ranged weapons with a normal range of 5 feet, so most net attackers must either make a ranged attack within 5 feet of a foe or at long range. Either way, the attack suffers disadvantage. Crossbow experts can make ranged attacks within 5 feet of a foe without disadvantage. Sharpshooters can make ranged attacks beyond normal range without suffering disadvantage.

4. Invisibility, a spell that makes you invisible and monitors your movements to see if you intended to hurt someone, rates as simpler than Greater Invisibility, a spell that just makes you invisible.

3. Creatures who lose temporary hit points to caltrops can have full health and still move slower. Worse, they can’t regain their speed until they take more damage. The speed penalty from caltrops only ends when you regain a hit point, so you might need to lose more hit points to have some to heal.

2. A cleric can cast a spell like Aid with somatic and material components while holding both a mace and a shield with a holy symbol. But casting a spell like Cure Wounds that drops the need for material components requires putting the mace or shield away. Fewer components makes the spell more cumbersome because the shield only doubles as a somatic component when you also use it as a spell focus to satisfy a need for material components. Confusing? Awkward? That’s why I’ve never seen this rule enforced. (See the Sage Advice Compendium.)

1. By relaying an object from creature to creature on consecutive turns in a 6-second round, a group can make the object outrace a jet. In an actual fight, everyone acts at the same time. But in the game, turns serve as a simple but unrealistic way to make sense of 6 seconds. To squeeze turns until their absurdity shows, just have everyone on the party run a relay. If each of 7 characters dashes 60 feet before passing a baton to the next person, the baton travels at almost 50 miles per hour. The more characters who can move an object in a round, the faster it goes. To weaponize this quirk, hire 1000 laborers to pass a 10-foot pole and create a peasant railgun. No DM allows such weapons, but some encounters force players to transport things like potions or keys across the battlefield. DM Tom Christy enforces a house rule where no object can be manipulated by more than one of each type of action in a round. No chaining move actions to rocket something across the battlefield.

All this points to the importance of the DM. D&D designer Dan Dillon writes, “If a confluence of circumstances in D&D creates rules interactions that don’t make sense to you, ignore it. Change it. Do what makes sense for the given situation the characters find themselves in.”

For example, if you prefer a game where shooting into darkness yields disadvantage, impose it. If you want Lucky characters to always suffer a disadvantage from disadvantage, then tweak the rule. Lead rules designer Jeremy Crawford suggests letting the lucky character choose between either (a) the lower of the two disadvantage dice or (b) the lucky die.

“The rules aren’t written to cover every possible circumstance,” continues Dan Dillon. “Think about how many pages would have to be added to the already 316-page Player’s Handbook if we added every possible ‘unless’ to a rule that applies advantage or disadvantage to an attack roll.”

The designers could try to patch every quirk and corner case, but if they did, you wouldn’t want to play that game.

How the Flawed Hooks in Descent Into Avernus Might Make D&D Players Feel Railroaded

Everyone giving Dungeons & Dragons advice tells dungeon masters how to start an adventure with a hook. This includes me, last week. That advice usually stops after the first hook, and it shouldn’t. Sure, adventures that lure characters into the unknown seeking treasure only need one hook. But just about every adventure with a more complicated premise serves hooks from start to finish. Those hooks offer choices and lure characters along a course that shapes into a story.

The hooks that come after an adventure’s start often go by names like clues, secrets, or leads. In earlier posts, I favored the term “leads” because the word matches one essential purpose: Leads reveal ways for the characters to reach a goal. (If the idea of leads seems unclear, see instead of plots, prepare secrets, clues, and leads.) The word “hook” emphasizes a second essential: Hooks entice players to chase a particular goal.

By either name, hooks and leads must accomplish two things: They entice characters to pursue a goal and they reveal ways to reach that goal. Skipping one of those parts causes adventures to stumble.

Leads point a direction, but sometimes they still need to sell a new goal.

When an adventure needs to point characters toward a new goal, the leads need to sell that new goal. Many adventures fail to close the sale. Most often, an adventure starts with a promise of gold, and then presumes that a band that may only include murderous treasure hunters will happily switch to, say, battling princes of elemental evil—for free.

My last post describes how Baldur’s Gate: Descent Into Avernus attempts this sort of flip. The opening hook appeals both to the treasure hunters and the do-gooders. Later though, the adventure asks players to send their characters to Hell for the slimmest chance of rescuing a damned city. The paladins might volunteer, but any sensible rogue would say, “I’m out.” Still, the rogue players want to play D&D, so their characters dutifully tag along.

In an adventure like this, either the dungeon master or the players can rethink the party’s motivations, smoothing the rough patch. Often, no one does. Many longtime players face such situations often enough to feel numb to the dissonance of having to do something their characters wouldn’t do just to keep playing. The rest feel railroaded.

Hooks sell a goal, but they need to offer a sensible direction too.

When an adventure runs short of hooks or leads, everyone notices. The party gets stuck and the DM finds a way to drop new clues. The adventure may stall, but the obvious trouble invites a solution.

Imagine trying to start an adventure by only revealing that long ago a mighty warrior hid a magic sword in a long-forgotten location. That tidbit would only leave players waiting for more, because without any clues, the incomplete hook rates as backstory. Every adventure starts with a hook that (1) entices the characters to follow some goal and (2) reveals ways to reach that goal. Number 2 rarely gets discussed because DMs seldom botch it. At the start of a scenario, no DM dangles a hook that lacks any clues the characters can follow to the goal.

The more insidious problem appears when an adventure offers clues that don’t seem to lead closer to the goal. The players see a lead, but no reason to follow it. Few players want to derail an adventure that plainly offers a direction, so the players dutifully follow the lead while ignoring that dissonance that comes from doing things just because the DM pointed the way. Following an apparently useless lead makes players feel confused at best, railroaded at worst. To the DM, the adventure seems to run smoothly, so the problem goes unnoticed by the person who could have corrected it.

Descent Into Avernus suffers from this trouble. (This discussion includes spoilers, but hardly more than the adventure’s title.) D&D blogger Merric Blackman writes, “The trip to Hell offers no reason for the characters to believe they can improve things. You stopped a threat to Baldur’s Gate. Why now to Avernus?

“‘If the characters think they have any chance to rescue Elturel, Liara strongly urges them to pursue that quest.’ That’s why the PCs descend into Avernus. Not great, huh? Why do the PCs think they have a chance?”

Game designer Justin Alexander is more blunt. He explains how Descent Into Avernus keeps asking players to follow directions just because they lead to more D&D. “The entire campaign is just this one structure repeated infinitely: A non-player character tells you where to go, you go there, and then find another NPC who tells you where to go.” This pattern works when the NPC’s directions show a way closer to the goal. The leads in Avernus fail that standard. “The problem is that the designers aren’t designing a situation. They aren’t thinking of the game world as a real place.

“Why does the adventure assume the characters will simply plane shift to Hell without having any reason for doing so? Because an NPC told them to! Why not also have the NPC give them a coherent reason? Because it doesn’t matter!”

The design only aims to route players from scene to scene. In play, the party sees a lead that they know the adventure expects them to follow, so they do. To the DM, the adventure appears to work, but unless players feel numb to dutifully playing DM Simon says, they feel railroaded.

Alternately, when hooks clearly point characters toward their goals, even linear adventures, even railroads, can work magic.

“A good railroad, at a certain level, is like a good magic trick: The players won’t really believe that magic is real, but a good magic trick will let them suspend disbelief just long enough to be amazed. The most important technique for the railroaded scenario is to frame the meaningful choices in such a way that the players legitimately want to make the predetermined choice.” writes Justin Alexander.

“The GM never forces a card on them. In the end, they do the magic trick to themselves. When a railroaded scenario pulls this off, the suspension of disbelief is perfect: Players never feel as if they were forced to do something. They’re able to remain completely immersed in their characters, feeling as if the world is unfolding in direct response to their actions.”

In a successful narrative adventure, the DM keeps laying track by dropping hooks. Each one shows a course that brings the characters closer to their goal, so the players willingly choose to follow. 

Good hooks power meaningful choices even better than linear scenarios. When players find enough leads, they face choosing which one to follow. Making choices and seeing outcomes generates the fun of role-playing games. Leads also offer more flexibility than plots. DMs can reveal them whenever players need to find a direction or to face choices.

As for Descent Into Avernus, the adventure brings evocative locations and vivid characters to an unforgettable journey through Hell. Your heroes get to adventure in Hell! Fixing the weak connections merits a bit of creative work. For ideas, see Merric Blackman’s account of running the campaign, Justin Alexander’s Remixing Avernus, and my own post Improve the Start of Baldur’s Gate: Descent Into Avernus With These 2 Add-On Adventures.
