Demi-Human Level Limits, D&D Adventurers League, Open Rolls, and More From the Comment Section

Time for another visit to the comment section, starting with a request.

DM Bill writes, “Could you do an article about humans versus non-humans, and the importance of the First Edition level cap, please!

Until third edition, Dungeons & Dragons limited non-human characters to maximum levels in most classes. D&D co-creator Gary Gygax favored the sort of human-dominated fantasy that appeared in the fiction that inspired him. To Gary, demi-human level limits explained why humans dominated D&D worlds despite the extraordinary talents and longevity of elves and dwarves. Gary wrote, “If demi-humans, already given some advantages, were as able as humans, the world would be dominated by them, and there goes the whole of having a relatively familiar world setting in regards to what cultures and societies one will find in control. So a demi-human is unlimited in thief level only, as that this a class not destined to control the fate of major groups or states.

I doubt the rare humans who become capable enough to overshadow non-humans really explain human prevalence in a D&D world, but the level limits encouraged playing human characters and tended to fill adventuring parties with humans. Of course, some groups simply ignored the rule.

Gary wrote, “Why are humans more able to rise to higher levels than demi-humans? Because the gods say so, and don’t like pointy eared types with curly-toed shoes, squat miners with big beards, hairy-footed midgets, etc.” Gary intended the comment as harmless fun at the expense of make-believe creatures, and in 2005 most readers read it that way. But now the comment reads in a way Gary surely didn’t consider. In our history, people have justified inflicting countless horrors on other humans by claiming that God disapproved of some group. Talking about even fictional half-humans like this raises uncomfortable echoes.

Nowadays, many players feel drawn to the exotic character races. In an apt post, John Arendt compares the typical Adventurers League party to the Munsters, a collection of exotic, monstrous types with perhaps one human for contrast. “When an AL player sits down with a shadar-kai shadow sorcerer, there’s no point in even asking them what they’re doing in a large human city; the players haven’t considered it. The culture is about players assembling races and classes because the mechanical bits sound cool.” I see many players drawn to exotic characters for their story, flavor, and for the chance to play someone who seems extraordinary even in a D&D world. That urge never succeeds as well as players hope. Even in the Forgotten Realms, a party that includes a deep gnome, a tortle, a triton, a shadar-kai, and a guy with flaming hair would alarm ordinary folks, but to keep the adventure on track everyone treats such groups as unremarkable.

D&D’s Animal Companions and Familiars—Choosing the Right Pet For Your Character

In D&D’s Animal Companions and Familiars—Choosing the Right Pet For Your Character I touted the power of find familiar.

Seven writes, “When used correctly find familiar is way overpowered. My owl scouts ahead so we don’t get ambushed. My owl flies down the tunnel triggering the glyph. My owl scouts the dungeon as I watch. Oh, it dies. Ok, I ritually cast. Let’s burn an hour.

I disallowed the Help action in combat for familiars and my players try not to abuse the power granted by the find familiar, but I miss the old days when you suffered a consequence when your familiar died.

Ilbranteloth writes, “Why can’t a spirit have a personality? Gwenhwyver was a magic item, but had a personality and sting connection to Drizzt. Having a personality is up the player. It has nothing to do with being a flesh and blood creature that only exists in our imagination.

If find familiar feels too strong for a 1st-level spell, I suggest limiting it by adding two elements:

  • Treat the familiar as an non-player character with an attitude and a some desire to avoid getting hurt. As controlled by the dungeon master, familiars follow orders, but not necessarily cheerfully or recklessly.

  • Doors. Scouting familiars lack the hands needed to open most doors.

The post also suggested find steed and find greater steed to players interested in gaining a mount.

Larissa writes, “Find greater steed is a 4th-level spell, so paladins won’t get it until level 13. For the greater steed, play a bard and take the spell at level 10, because for a paladin it’s a long wait.

Steal This Rule: Flashbacks and Heists in Dungeons & Dragons

The post Steal This Rule: Flashbacks and Heists in Dungeons & Dragons explained how to adapt rules for flashbacks to Dungeons & Dragons.

Morten Greis writes, “It is kind of weird to see flashbacks-mechanics coming back as if it was a wholly new thing. In 2010, I wrote this: Using Flashbacks in Your Roleplaying Game. It is a great mechanic, though, and it is good to see people using it more.

For gamers interested in flashbacks, Morten’s post gives more suggestions for using the mechanic to enhance your game.

Captain Person writes, “There’s a product on DMs Guild called Here’s To Crime: A Guide to Capers and Heists that adapts the Blades in the Dark heists to fifth-edition D&D.

Michael Lush writes, “‘The Arcadian Job’ episode of the Netflix series 3Below: Tales of Arcadia had an interesting flash-forward spin on this.

The protagonists need to break into a high security military base, but the action focuses on the planning session where they narrate what they are doing and their plans appear on screen.

We infiltrate under cover of night and cut through the wall with…BZZZZZZT!!! No, can’t do that! Look the wall is electrified…

We infiltrate under cover of night and short circuit the wall (failed Security roll. An alarm rings, guards show up, and we die in a hail of blaster fire! No, can’t do that…

OK. Infiltrate under cover of night, insulate the wall with rubber matting (rolls a success), and climb over the…ZAP!! Oh sentry turrets.

Hmm. The wall is a bust. How about the gate?

Once they bypass all the security, the flash-forward planning switches back to normal real-time play.

In a tabletop game, such planning steps would resemble a video game where when you run into trouble, you restore to the last save. The story that develops includes no failures because the framing story shows how the players planned around all the pitfalls.

The 3Below episode finds a new take on the usual storytelling approach to planning. Typically, if the characters make a plan on screen, we know the plan will fail. The narrative lets us enjoy the surprise and tension of seeing the plan unravel. But if we never see the planning, then the plan succeeds. Narratives never show heroes making successful plans because revisiting a familiar plan as it unfolds would prove less interesting.

lunaabadia writes, “One of the mechanics I really like in Gumshoe games such as Night’s Black Agents is the Preparedness skill. It represents this concept that your character has a knack for planning. As with other skills in the game, you spend one or more points to add to a roll for what you are trying to accomplish. You might say, ‘but of course I brought night goggles,’ and you make the roll. As you noted above, the whole point is to zip past the boring hours players can spend wondering what gear to bring. Preparedness answers the question of whether you brought it and frees players’ brains to focus on the action.

I would guess Preparedness could be done with Inspiration, and in a heist session it could make a lot of sense to give each player Inspiration at the start of the mission, representing their planning. Do you spend it on a roll? Or do you hold it in case you need to do a flashback?

7 Dungeons & Dragons character builds absurdly good at one thing

The post 7 Dungeons & Dragons character builds absurdly good at one thing continues to attract readers and comments.

Geoff writes, “Disciple of Life doesn’t apply to goodberries. It says ‘whenever you use a spell of 1st level or higher to restore hit points to a creature, the creature regains additional hit points.’ Goodberry is a spell that summons magical berries, not a spell that restores hit points to a creature.

Your interpretation adds up, but officially the interaction works. See this Sage Advice post.

Chivalry & Sorcery: What if Gary and Dave had not found the fun?

In Chivalry & Sorcery: What if Gary and Dave had not found the fun?, I had a bit of fun at the expense of one of the earliest fantasy roleplaying games.

Shane Devries tells how his group started playing Chivalry & Sorcery by ignoring most of the rules, and then slowly added complexity. “Over a period of a couple of years we were playing the entire system as written and NEVER looked back. Over time D&D and Palladium dropped away and by 1985 all we played was Chivalry & Sorcery, which we still play to this day. All my players prefer C&S BECAUSE of its complexity and revel in the system and what it has to offer. The older players in my group with decades of experience will not go back to D&D or any other system for this fact.

Why You Should Play in the D&D Adventurers League (and a New 1-Sheet Quick Start)

The post Why You Should Play in the D&D Adventurers League (and a New 1-Sheet Quick Start) prompted some readers to share their bad experiences dropping in for Adventurers League games.

Alphastream responds, “The experience really varies, but bad areas are uncommon. I’ve traveled for work across the US and tried many different stores. I would say under 15% are truly bad, primarily due to bad store management. And, even when I’ve found a bad one, I’ve offered to DM an additional table, recruited players via MeetUp (or a similar site), and had a great time. I’ve had far better results finding AL tables and meeting cool players/DMs there than I have with trying to find decent home groups. Good stores are also very welcoming to new players. Stores overall are changing a lot these days, mastering skills to draw in customers through many different programs and creating healthy and safe spaces focused on fun.

My local game store draws players interested in sampling D&D, and while many become regulars, many don’t return. The conversion rate rises when prospective players arrive at a table starting a new campaign or hardcover. When players get slotted into an ongoing game, they seem to find the experience more daunting. An ideal welcome would feature short seasons of low-level games that fed into a higher-level experience. Wizards of the Coast should support a program like that. I can even suggest a name for it.

How New Changes Created the 4 Most Annoying Spells in Dungeons & Dragons

In How new changes created the 4 most annoying spells in Dungeons & Dragons, I wrote, “By the end of the encounter, player characters go from one beguiled victim to the next, raining attacks on the defenseless pinatas. As a DM, I may be biased, but I think the least fun scenes in the game come when PCs beat helpless foes to death.”

Acemindbreaker writes, “Why play that out? If it’s clear that their opponents stand no chance, montage it instead of rolling the dice. ‘So, your opponents are all helpless as long as your wizard keeps up hypnotic pattern. Are you intending to kill them all?’

‘Yeah.’

‘All right, easy enough to do. Once they’re all dead, what next?’

Zachiel cites maze as an annoying spell that can wreck most player characters. Wizards aside, PCs never boast enough intelligence to make a DC20 check on less than a 20. Lucky for players, few will ever face the 8th-level spell. However, the spell appears on Acererak’s list in Tomb of Annihilation, so I got to send someone to the labyrinth, and that delighted me. My joy probably makes me a mean DM, but we DMs so rarely get to thwart players with such potent magic.

How to Run Better D&D Games By Doing Less

How to Run Better D&D Games By Doing Less suggested ways DMs can delegate some of their tasks to players.

Daniel writes, “My players enjoyed reciting expository dialog (usually in the form of flashback conversations involving NPCs). Maybe this is because some of them had more of an acting background than a gaming one. It does mean that I had to compose and print the dialog in advance but it then saved me having to do too much talking (and switching personas) during a session.

In D&D, Letting Everyone Roll Certain Checks Guarantees Success, So Why Bother Rolling?

The post In D&D, Letting Everyone Roll Certain Checks Guarantees Success, So Why Bother Rolling? raised a question that drew plenty of interest.

RobOQ writes, “As a player I tend to get annoyed at rolling for every imaginable thing. I prefer, both as a player and a DM, to go by the rule of ‘if there isn’t an interesting outcome to both success and failure on the roll, leave the dice where they are and just describe the more interesting outcome.’ I see very little point in rolling dice where a failure means the situation doesn’t change at all.

Insight Played Wrong Can Become the Most Unrealistic Thing In D&D, a Game With Djinns In Bottles Who Grant Wishes

In Insight Played Wrong Can Become the Most Unrealistic Thing In D&D, a Game With Djinns In Bottles Who Grant Wishes, I betrayed a low passive insight by suggesting that a liar might avoid eye contact.

Dr Sepsis writes, “Someone who is lying is more likely to make eye contact as they check to see if they’re being detected.

HDA writes, “Instead of rolling dice to get information, make your players think, observe, ask questions, learn from the world around them. As the DM playing a non-player character, maybe raise your eyebrow a bit. You know, emote. What is even the point of having intrigue and deception in your game if the players can just roll to see through it?

8 Fast Facts About D&D’s Magic Missile Spell

In response to 8 Fast Facts About D&D’s Magic Missile Spell, Kristen Mork pointed me to Sage Advice that said each magic missile should provoke a separate concentration check.

This answer defies the answer the design team gave when they introduced the game, but fine. In practice, the newer ruling makes magic missile an efficient way to break concentration and to finish fallen characters. (See Can a DM Have Monsters Kill Fallen Characters Without Bringing Hurt Feelings?)

After penning my 8 facts, I watched a Q&A panel by TSR editor Tim Kask that expanded on one. Gary Gygax’s debates with Tim helped shape Advanced Dungeons & Dragons. “The only thing that I won was that magic missile always hits for damage,” Tim said. “It took me two-and-a-half weeks of arguing. I kept telling him that that’s the only thing the little guy gets and if it’s hit or miss, then he’s dead.”

Dan writes, “I would actually argue that the magic missile and shield spells were inspired by a bit earlier in that scene from The Raven, whereby Karloff produces magical knives and an ax and sends them toward Price, who blocks them with magic barriers.

The small exploding balls at the beginning of your embedded video are much more likely to have been what inspired Melf’s Minute Meteors.

Steve Blunden writes, “Seeing both these clips, and of course the wizard duels in Harry Potter inspired me to see if the rather colourless counterspell could be dramatically improved. When a character tries to cast counterspell, the player should be encouraged to describe what this might look like. E.g. if counterspell is used against fireball, the player can describe the counterspell as a jet of water leaping out of their hand to douse the fire.

In Making Counterspell Awesome, Mike “Sly Fourish” Shea recommended this approach.

How Character Death Lands D&D in a Tug-of-War Between Game and Story

The post How Character Death Lands D&D in a Tug-of-War Between Game and Story prompted alphastream to share some history.

Second edition and earlier simply had fragile PCs. You could die easily, end of story.

Third edition had monsters that were absolutely brutal at all tiers, plus some really exploitable loopholes (such as non-associated class levels) that created sky-high challenges. This all meant that if the DM knew how to craft monsters,characters could easily die, even when they had full hit points. Unfortunately, it was incredibly taxing to modify monsters.

Fourth edition gave PCs too much of a safety net between hp and healing surges, though the edition also had some amazing challenges (especially after the developers went back and corrected the monster design math).

Fifth edition on paper looks more fragile than 4E, but it has not been in play. Characters are very resilient and have a lot of hit points compared to monster damage. Monsters are often given special abilities and to balance that they do less damage, but the abilities don’t actually threaten PCs with death. This problem is even worse at high tiers of play, where monster damage is absolutely shameful. Most monsters have no chance. If they hit 100% of the time they still could not drop all the PCs to 0 hit points. And when that isn’t the case, there is no way for the PCs to be defeated in most fights. To me, the 5E solution is pretty simple: add damage.

Abelhawk writes, “I have a couple of house rules that make death a bit more dangerous and limiting:

1. When a character is brought to 0 hit points, they gain a level of exhaustion. Levels of exhaustion gained in this way go away after a short rest, or if the character is brought to half their hit point maximum.

2. When a character dies and is brought back to life, they receive one permanent death saving throw failure. A character with three permanent death saving throw failures cannot be brought back to life by any means.

Imposing exhaustion on characters raised from 0 hp rates as a fairly popular house rule. As for the second house rule, I like the idea of limiting characters to some maximum number of resurrections.

Turning Character Deaths in D&D Into Deals that Benefit Game and Story

In the post, Turning Character Deaths in D&D Into Deals that Benefit Game and Story, I wrote, “If D&D players wanted a game where fighting rated as a last resort, they would play Call of Cthulhu or the Dallas Television RPG, where you can’t shoot JR.”

Jacob Blalock responds, “Most people who want to play have to take what they can get in terms of finding a group to play with, and that means they mostly play the most recent edition of the most widely recognized RPG, 5th-edition D&D.

Jacob makes a fair point. Some roleplaying gamers play D&D because the game’s popularity makes finding a group easier, rather than because the game perfectly suits their tastes.

Cymond writes, “I was recently considering the idea of a house rule: Let a dying character remain conscious but unable to act or speak loudly. You can still have those dramatic deathbed moments where they confess their eternal love, beg to be avenged, plead with the unscrupulous rogue to please save the world, etc. Or maybe say that they don’t die immediately after 3 failed saves, but are beyond saving with anything less that the same things that would resurrect them, and save the deathbed moment until after combat.

Tardigrade writes, “I strongly feel that if a character death is a problem for your narrative, then you’re playing the game wrong. If you are narrating a story, go write a book. If you are trying to create an experience that challenges players, then play D&D, design the game so that their choices matter and don’t fudge the dice.

BlobinatorQ responds, “Ultimately it comes down to the group. If the group wants D&D to be nothing but challenges, and wants the stakes to be high with character death always on the table, then so be it. If the group wants to build and be invested in a narrative, and don’t want people left out of the experience due to some unlucky dice rolls, then things should be crafted to suit that. There is no one right way to play D&D, it can be a very different game for different groups.

When I explained the problems that death creates for a story, I focused on the story a particular player imagines for their character. The story of a D&D campaign can stand some character deaths, but that doesn’t cushion the blow a dead character brings to their player.

Ilbranteloth notes that the 1st-edition rules for characters at 0 hit points were forgiving, giving players at least 7 rounds to help a fallen character.

What differs significantly are the consequences of your near-death experience. And this is where I think 5e has made it much less of a thing. In AD&D, if you were reduced to 0 hp, then once you were restored to at least 1 hp with mundane OR MAGICAL means, you were in a coma for 10-60 minutes. Then you had to rest for a full week, minimum. A Heal spell was required to avoid this period of rest.

There was a significant consequence already built into the game for dying and we avoided it because it generally put the adventure on hold while the party headed back to town to rest and recover.

In most cases, it also meant nobody was out of the game. The entire party went to town to rest and resupply, and of course you didn’t have to play that out. So it was a short, we-failed moment.

If this one rule was still in effect, then the risk of death is back, without having to kill any PCs. And it also has the effect of reducing the risk of actual character death because players try to make sure they aren’t reduced to 0 hp.

I have now learned that when I played AD&D, everyone I played with got the rules for 0 hit points wrong.

The post Print My Custom D&D DM Screen to Defeat the Basilisk explained why I typically use a DM screen.

Alphastream writes, “When I run organized play games and don’t use a screen, I get maybe one person every four or so tables that can’t help but look at my notes. And when that happens, they tend to look often… enough that it distracts me! So, I tend to use a screen. Plus, I like collecting/buying screens and then I get to show them off.

I find screens can be effective for drawing attention from others. In a public space where that’s valuable, such as to get other people walking by to be interested and sit down, it can be an asset.

The least valuable aspect of a screen, for me, is what’s printed on my side. Outside of a few things, such as conditions, dispel magic, and counterspell, I never look anything up. What I’ve been doing lately is draping two pieces of paper taped together over one part of my screen. Facing the players is a map of the general area of the world. Facing me is a list of the character names and info I want for help with roleplay: race, background, class/subclass, etc. I add a list of important campaign NPCs and similar notes. That’s stuff I reference all the time.

I have one young player who finds the basilisk so irresistible that I often see his eyes rise like Kilroy over the top of my screen.

The post’s sidebar explained why I roll in the open and raised some debate.

I wrote, “If I had rolled behind the screen and simply announced a pair of crits, the event would have fallen as flat as a card trick on radio.”

Navy DM responds, “If players have that low level of trust in their DM, then that is a whole different issue.

Sam replies, “Sounds more like the excitement and watching the dice roll than not trusting what the DM rolled to me.

Marty replies, “Exactly. The tension comes from seeing the rolls and reacting. Rolling in the open has completely changed my game for the better.

Most DMs who roll behind the screen acknowledge that they occasionally override rolls to shape play, aiming for a better experience. Rather than players trusting their DM to stick to a die roll, I assume the players trust the DM to not abuse their privilege in some way. What would count as a betrayal of trust?

To be clear, I make some rolls in secret to conceal information from the players. I often roll hidden perception and especially insight checks to avoid revealing secrets.

Beyond the advantages I described in the post, rolling in the open forces me to honor any surprises the dice send my way. If a secret roll upends my plans, I might feel tempted to ignore the roll and take the comfortable path I expected. For me, rolling in the open feels a bit more exciting, like dungeon mastering without a net.

Other DMs feel like sometimes overriding rolls lets them craft a more dramatic game. I respect that perspective, but it’s not for me.

Insight Played Wrong Can Become the Most Unrealistic Thing In D&D, a Game With Djinns In Bottles Who Grant Wishes

In Dungeons & Dragons Wisdom (Insight) checks commonly lead players to pile-on checks. One character talks to someone, asks to roll insight, and then everyone adds their roll. The group supposes that just one success will spot a lie. If the dungeon master allows such checks, someone almost invariably uncovers any deception. By such rules, lying to big groups becomes impossible, which makes insight checks the most unrealistic thing in a game with djinns in bottles who grant wishes.

If you want any intrigue and deception in your game, never roll group insight checks where one high roll brings success. Instead, opt for one of two methods. The choice of method depends on whether you, as DM, want players to roll their check.

  • If the players roll, the numbers on the dice give players unearned hints. Low numbers tell the players they probably failed and not to trust their insight; high numbers suggest they succeeded and that, for instance, an NPC who appears honest can be trusted.

  • If you roll in secret, the players feel deprived of some control over their fate. After all, some DMs will fudge rolls to protect a planned narrative. Also, players like rolling dice, especially if rolling gives unearned hints.

Players roll group checks

If you allow players to roll, call for a group check where everyone makes a Wisdom (Insight) check and at least half the group must succeed.

This method may see odd, because group checks apply to situations where one failure could potentially cause the whole group to fail. For instance, one noisy character could alert the guards the party wants to sneak past. But group checks actually fit insight checks with no sure answers. If at least half the group succeeds, the successful characters reveal their insight to the others. If too many characters fail, the group suffers a difference of opinion that leaves everyone uncertain. Or perhaps Terry the Apothecary just proved hard to read.

Don’t tell players which characters suspect lies. Players who know that and their die rolls gain a metagame-based lie detector.

Set the difficulty class for the checks by adding 10 to the liar’s Charisma (Deception) bonus, so the DC equals the liar’s passive deception.

DMs roll a single check

As a DM, you could roll a secret, group Wisdom (Insight) check, but tracking several die rolls and bonuses would slow the game. Instead, roll one check for the character in the scene with the highest Wisdom (Insight) bonus. By using the highest insight score rather than a group of scores, this method benefits the players. On the other hand, the players lose any hints they gain from seeing the numbers. Don’t grant advantage for help coming from the other players. We don’t want to make spotting lies unrealistically easy. This method presumes that the rest of the group offers little help to the most insightful character. Either the others also spot the deception, or they muddy the waters by being more easily fooled.

Alternately, roll one Charisma (Deception) check for the liar against a DC set by the group’s highest passive Wisdom (Insight) score. If the deceiver fails, describe signs of deception. On success, the liar seems legit. I like this reversal because the odds stay the same, but you roll on behalf of the more active character.

Usually a liar only needs to make one deception check, but if the pressure increases thanks to sharp questions, or their lies begin to unravel, you might require fast talking and another check.

Success and failure

Whatever type of check you use, if the outcome favors the players, a liar shows signs of deception and an honest character seems trustworthy. Otherwise, the target of the check seems hard to read.

Rather than flatly stating that someone lies, describe signs of deception: A lying person may sweat or otherwise appear anxious. Perhaps they start speaking in a manner that seems rehearsed. Someone with something to hide might avoid eye contact or become hesitant while speaking. Perhaps their words and body language fail to match. For example, they might nod yes during a denial. For countless more symptoms, search the internet for “signs of deception.”

When a check goes badly against the players—call it a fumble even though D&D lacks critical failures—the party may get the wrong impression. Perhaps an honest person shows misleading signs of deception. Follow what works for the story and your inclination to deceive the players. Maybe an honest person just feels nervous in the presence of such esteemed adventurers (or such temperamental and murderous treasure hunters).

How to run an ambush

Group checks and the ambush

In “How D&D Next almost made knowledge count” and in “Is it noticed? How to run alertness,” I discussed the inevitable success that comes when a group rolls to gain one success. The reverse of this phenomenon appears when a group makes a check and just one failure can drag down the effort. The designers of d20 role-playing games mostly ignore these issues.

Credit the fourth edition Dungeon & Dragons designers for introducing a group-check rule for some tasks. From a game-play perspective, I like 4E’s group-check rule because it makes some group tasks possible. From a realism perspective, I fail to understand how three stealthy party members cover the racket from the clanking dwarf and paladin. In this post, I ignore the 4E rule, which I’ve never seen applied to perception anyway.

No situation highlights the problems of group checks more than the ambush. Using the simplest interpretation of the rules, everyone in a group setting an ambush must roll to hide, giving all a chance to doom the effort with a single bad roll. When the targets of the ambush arrive, every target gets a chance to spot that worst hider.

Based on real life, you might suppose that ambushes typically work. The group setting the ambush has the advantage of planning, preparation, and surprise. They just sit out of sight until their targets arrive. Unless someone sneezes or the targets have x-ray vision, the ambush works.

Based on the game, the word “ambush” describes a imaginary event that can never happen.

In “Is it noticed?” I suggested a fix. I advised assuming that the targets of an ambush take-10 to spot it. In effect, you set the DC for the ambushers’ hide check based on the targets’ lowest take-10 to spot. While this enables one creature to set an ambush, it still fails when a group prepares an ambush and everyone must roll to hide. My method only gives a group a chance of setting an ambush if the GM either (a) requires just a single hide check from the worst hider or (b) relies on 4E’s group check rules for the attempt to hide.

In a comment, Sr. Rojo suggested a method for handling ambushes that I like better.

How to run an ambush

To run an ambush, follow these two steps:

  1. Allow the group setting the ambush to take-20 in their effort to hide.This reflects their time advantage, which lets them pick a good site and then arrange themselves for maximum concealment. When you set an ambush, you have time to work out the best hiding place you can muster.
  2. When the targets reach the ambush site, ask them to roll to spot. The DC to spot the enemy equals 20 plus the ambushers’ worst hide bonus.Unless the ambushers stink at hiding, the DC to spot the ambush may be unattainable for some targets, and will present a challenge to the rest. Unlike most group spot checks, this check presents a reasonable chance of failure. Rather than assuming the targets of the ambush take 10 on their spot check, you can let them roll, and still give the ambushers a fair chance.

As with any spot check, you can limit the check to those characters keeping watch and in position to notice. If the party wants to an ambush a company, only the few soldiers on watch get a spot check, not all 100 enemies.

Take 20 and the rules

“When you have plenty of time, you are faced with no threats or distractions, and the skill being attempted carries no penalties for failure, you can take 20.” – Pathfinder Roleplaying Game Core Rulebook, p.86

Some rules lawyers might argue that the hide attempt does not qualify for a take-20, because it carries a penalty for failure. I disagree. Unlike climbing or disabling a trap, the act of perfecting a hiding spot carries no penalty for failure. Your best hiding place may not be good enough, but that comes later.

Dungeons & Dragons fourth edition and fifth edition both lack a take-20 rule, so this method requires some latitude with the rules as written. In practice, if the players set an ambush and you tell them they automatically roll a 20 on their hide check, no one will gripe.

If the players walk into an ambush, you, as the game master, set the DC they must reach to spot the ambush. Even in a game without a take 20 rule, a DC equal to the ambushers’ worst hide bonus plus 20 makes a good target.
