Edit Page Content

Dungeon World portrays a specific kind of fantasy adventure—one with elves and dwarves, heroes and villains, and characters struggling for riches and glory in a dangerous world. Maybe you’ve got an idea for something different—maybe your Dungeon World is set on a blasted desert planet, peopled by savage cannibals and ruled by haughty psychics. Or maybe you want to play a game where humans are the only race available, but they belong to clans or families as different from each other as a gnome is from a dwarf. All that is possible (and, in fact, encouraged) with a little effort. This chapter will explain how you can turn this Dungeon World into your Dungeon World.

Making Moves

The best place to start your journey into hacking Dungeon World is with the moves. Many of the fronts, dangers and other elements of your game will already contain custom moves, so it’s a natural, easy place to start. You might want to create moves to reflect the effects of some particular threat (“When you go alone into the Unhallowed Halls…”). You might create moves to cover something that’s particularly important to your setting (“When you swim in the dark waters…”). As you get more experienced you might create moves to expand a class or create your own class entirely.

Getting Started

Where do moves come from? You can start a move with the trigger. Some actions will just feel like they should be a move. This is the most common starting point for moves. You’ll see some action coming up and feel like it’s different enough from existing moves that it needs its own rules.

You can start with the effect. This is particularly useful for class moves. You know that casting a spell is something that the wizard does, so what triggers that effect?

Rarely, you can even start with the mechanics. Sometimes you’ll think of something cool, like a tamed demon whose happiness is a constantly varying stat, and go from there. Be wary of any idea that’s entirely mechanical. Since moves always start and end with the fiction, a mechanical idea is the least important bit of the move.

You can always use a move from another game, too. Dungeon World is just one of a handful of games that use moves and you might be inspired by one of those. It’s often not too difficult to modify an existing move for use in Dungeon World.

Types of Moves

What role the move is fulfilling determines what kind of move you’re creating.

Moves for dealing with the environment or special features you’ve added to Dungeon World are special moves. These moves are usually the GM’s domain, a place to make parts of the world stand out. Since moves are always triggered by the players, most moves like this should be written or printed somewhere everyone can look them over unless the move covers something that the player characters wouldn’t have any idea about.

Moves that reflect some special competency or power, or something the players do, are usually class moves. If the move is clearly tied to a specific class, add it to that class. If the move is tied to some concept that multiple classes might have access to, like a move only accessible to those that have seen beyond Death’s Black Gates, you can create a compendium class for those moves. A compendium class is like a mini-class, it’s a collection of moves around a fictional theme. We’ll deal with them in more detail later.

If your move is something the players do but isn’t associated with any specific theme or class it’s probably a basic or special move. If it comes up all the time it’s a basic move, if it comes up more rarely it’s a special move.

Moves made by the players in response to monsters, such as the effects of a disease or pressing on despite a focused blast of wind from an air elemental, are player moves associated with that monster. Player moves associated with a monster are fairly rare, most of the ways a player will interact with a monster are covered by the basic and class moves.

Moves made by monsters against the players aren’t player moves at all. They’re monster moves, simple statements of what the monster does. Trying to make every monster move into a player move will seriously hamper your creativity.

World Moves

Your Dungeon World is full of fantastic things, right? You’re likely to find that some of those fantastic things deserve or demand custom moves to reflect exactly what they do. Consider this one from Chris Bennet:

When you open a sewer hatch, roll+STR: ✴On a 10+, choose 2. ✴On a 7–9 choose 1.

  • You avoid being covered in feces and rotting animal entrails from the sewers above.
  • You avoid having a gelatinous cube land on you.
  • You find a secret back entrance to where the merchant’s daughter is being held.

This move is strong because it is tied strongly to a particular place at a particular time. This move was written by request for Jason Morningstar’s Dungeon World game as the players entered some particularly horrible sewers to find a powerful merchant’s daughter. Two of the options here are very directly tied to that precise situation.

Why would you write this move instead of just using defy danger? You wouldn’t, always. Opening a pressurized sewer hatch is certainly dangerous, you could use defy danger. This move does have the advantage of setting up the choices ahead of time. This is actually a very strong technique: if there’s a particular situation that is likely to cause defy danger, you can write a custom move that describes the tough choice to be made to save yourself some thinking in the moment.

The other strength of moves like this is they call out something as important. By making the trigger “when you open a sewer hatch” instead of “when you act despite an imminent threat” the move calls out that these sewers are always dangerous.

Class Moves

Each class has enough moves to take it through tenth level but that doesn’t mean you can’t add more. Adding moves to a class can demonstrate your idea of Dungeon World. Take this one, for example:

When you claim a room for your deity, mark every entrance and roll+WIS: ✴On a 10+, the room is peacebonded: no one can take action to cause physical harm within it. ✴On a 7–9, the room is peacebonded, but the show of divine power draws attention. You can dismiss the peacebond as you see fit.

This move presents a slightly different side of Dungeon World, one that can demand peace (something that usually doesn’t come easily to PCs). This may not be right for every Dungeon World game, but it’s a great way to show how your Dungeon World looks, reflected in the characters.

When adding a move, look carefully at what class it belongs to. Avoid giving a class moves that infringe on another class’s areas of expertise. If the thief can cast spells just as well as the wizard the wizard is likely to feel marginalized. This is why the multiclass moves act as one level lower, so that each class’s niche is somewhat protected.

Be careful with any move that provides the same benefit as an existing move even if the trigger is different. Moves that add to damage, in particular, should be avoided for the most part unless carefully crafted with interesting triggers. The same is true of moves that add to armor. The classes at present have damage and armor increases that reflect the overall danger of Dungeon World. Giving them more can negate potential threats.

New Classes

Once you’ve gotten your feet wet creating new moves and customizing the classes in Dungeon World, you’ll likely notice something. A class is just a collection of themed moves that work together to create a certain set of abilities and qualities that give the class their unique feel. If you’re up for it, creating a new class is the next natural step along the way.

Your first consideration should be how the class relates to the existing classes. No character exists in isolation, so you should think carefully about why this class is different.

An excellent first step to creating a new class is to think about what fictional characters you’d like to take inspiration from. Don’t slavishly follow what that fictional character can do (after all, they weren’t in Dungeon World) but use them as a guide for what’s so cool about that character.

The inspirations for the classes in this book are fairly clear, and made clearer by the notes in the margins. Note that not every inspiration is taken entirely: the wizards of Discworld inspired the slightly pompous style of the wizard, but the wizard is far more competent and casts spells more like a wizard from Vance’s Dying Earth. The inspiration is one of style, not an attempt to recreate what a certain character could do in a certain book.

With a clear idea in mind you have a few basic steps that aren’t a concern when writing single moves: HP, Bonds, Look, equipment, alignment, races.

A class’s HP is some base+Constitution. Base HP is almost always 4, 6, 8, or 10. Having more HP than the fighter and paladin will take the spotlight away from those characters unless you’re careful. Having less HP than the wizard is probably character suicide. 4 base HP makes for a class that is deliberately fragile, they’ll need help from others when the swords come out. 6 base HP is for classes that aren’t ready to fight, but can at least take a hit. 8 base HP is enough to take some hits and get into combat a little, while 10 base HP is for skilled warriors and those who have no fear of battle.

Damage is chosen from the dice available: d4, d6, d8, d10. The classes presented here all use a single die with no static bonus, but there’s no reason not to experiment with other options: 2d4 or 1d6+2, for example. High HP and damage tend to go together, but your new class could be a pacifistic brick wall or a glass cannon—fragile but dangerous.

Alignments show the starting outlook of the class. Most classes will have Neutral as an option, since only the most dedicated classes are so tied up to an ideal that the self can’t come first. A good alignment move is something that happens with some regularity and guides the player to a particular type of action they might not otherwise consider. An alignment that happens as part of the normal course of play, like “When you gain treasure…,” doesn’t really show the character’s ideals. Adding some requirements, maybe “When you gain treasure through lies and deceit…,” adds an element of ideals. Now the alignment says something about the character (they prize pulling a con on the unsuspecting) and requires the player to think about how they play. Alignment is a telling fact about the class in the world, too. Everyone knows that paladins are supposed to be paragons of Good and Law, right?

Bonds are where the class’ outlook shines through. It’s the place where you, the designer, will most clearly interact with the player at character creation. Unless the class is particularly social or antisocial, write four bonds. If the class is very connected to others, add a bond; if they’re cloistered, remove one. Avoid bonds that dictate a moral or ethical stance but do think about how your class interacts with their allies—the thief steals things but helps protect the party from traps, the fighter defends his allies and kills monsters that might harm them, the wizard knows secret knowledge and shares or hoards it. You can use the rules for writing new bonds as a starting point, but avoid including proper names in starting bonds.

Look is largely left to your imagination. This is an excellent spot to think about your fictional inspiration. What did they look like? How could they look different? Including at least one choice about clothes helps establish style without making the player think about buying clothes.

The equipment choices should always include at least one weapon option and one armor option unless the class is clearly lacking in fighting skill. Dungeon rations are also pretty much required; a starting character without food going into a dangerous area borders on stupid.

Compendium Classes

A compendium class is a class only available to higher level characters who meet specific requirements. They’re called compendium classes because they first appeared in the Compendiums for Dungeon World Basic. A compendium class is the way to go for a concept that can be layered onto multiple other classes.

The basic structure of a compendium class is to have a starting move that is available only to characters who have had a certain experience, like this:

When you enter the bodily presence of a god or their avatar the next time you gain a level you can choose this move instead of a move from your class:

Divine Bond

When you write a new bond, instead of using the name of another character you can use the name of a deity you’ve had contact with. Anytime a bond with a deity applies to the current situation you can mark it off (as if it was resolved) to call on the deity’s favor in a clear and decisive way that the GM describes. At the end of the session you then replace the marked off bond with a new one, with a deity or player character.

Note that the move is only available after the character has done a specific thing, and even then only at their next level. Compendium classes are best when they rely on what the character has done, not stat prerequisites or anything that happens without the player’s action. A compendium class that is available to anyone who just gained 5th level doesn’t stand for much; one that only applies if you’ve been to Death’s Black Gates and lived to tell the tale is more interesting.

A compendium class also usually has 2–3 moves that can be taken only if the starting move is taken. These are just like normal class moves, just with the requirement that you have to have already taken the starting compendium class move.

Compendium classes are ideal for concepts that don’t quite inspire a full class. If you can’t think of what the class looks like or how much HP it has, or if the class overlaps with existing classes, it’s probably better as a compendium class.

Adventure Moves

Adventure moves deal directly with the adventure underway. They can move the action along, change the rewards, or transition from one adventure to another.

If you’re running a short game, maybe at a convention or game day, you may find that you want to front-load the experience a little more. Here’s a move that covers “the adventure so far” so that you can get straight into a short game in media res.

Stalwart Fighter: As if the bandits weren’t bad enough! As if all the sword wounds, bruises and beatings at the hands of your enemies were insufficient—now this. Trapped underground with your adventuring companions when all you wanted was to return to the town and spend your well-earned bounty. No such luck, warrior. Sharpen that sword! Certainly, the others will need your protecting before safety is found. Just like last time. Once more into the breach, right? I swear, one of these fellows must owe you a favor or two by now…

Have a look around and roll+CHA. ✴On a 10+, choose two party members. ✴On a 7–9, choose just one. ✴On a 6-, you’re surrounded by ingrates.

At a moment of need, you can cash in a favor owed you by one of the party members chosen. They must change their action to one of your choosing, once. You may not give them an action that would involve them directly taking damage, giving up a magic item they already own or coming to immediate harm. Use it to make them agree with you, or give you that extra ration you want, or giving you their slot in the loot lottery. Leverage is sweet.

The most important part of this move is not the roll or the effect, but the information and tone. It sets the stage for a quick adventure and gives the player reading it a starting point to work with. The roll and result here are interesting, but don’t greatly change the flow of the game. Handing out a set of these, one to each player, along with a playbook, is a great way to run a con game.

You can also adapt the End of Session move to reflect the adventure you’re running. When doing this it’s key that you show the players the new End of Session move. The goal isn’t to keep them in the dark about what earns XP, but to make the XP awards tie directly to this adventure.

When you end the session, instead of using the normal end of session questions, use these:

  • Did we learn something about the Cult of the Scaled God?
  • Did we rescue a captured villager or help defend the village of Secor?
  • Did we defeat a major agent of the Cult of the Scaled God?

Move Structure

Moves always follow a similar structure. The most basic parts of a move are the trigger (“when…”) and the effect (“then…”). Every move follows this basic format.


Triggers are often fictional actions undertaken by the player characters but they can also be part of character creation or trigger at the beginning or end of a session. Note that a trigger never deals with precise units of time. Don’t write a move that begins “When you start a round adjacent to a dragon.” There’s no rounds (and adjacent is maybe not the best phrasing, as it sounds removed from the fiction of standing next to a damned fire-breathing dragon). Prepare Spells isn’t “When you spend one hour studying your spellbook” for good reason. Time in Dungeon World is a bit fluid, like in a movie where pacing depends on the circumstances. Don’t rely on concrete units either around the table (rounds) or in the fiction (seconds, minutes, days).

Here are some broad types of triggers:

  • When a character takes action. Examples: Discern Realities, Arcane Art (Bard), Command (Ranger).
  • When a character takes action under specific circumstances. Examples: Hack and Slash, Seeing Red (Fighter), Backstab (Thief).
  • When circumstances dictate, no character action. Examples: Order Hirelings, End of Session.
  • When a character uses a thing. Examples: Magic items, Heirloom (Fighter).
  • From now on. Examples: Serenity (Cleric), Poisoner (Thief).


Moves effects can be anything you can think of; they are as limitless as your ideas. Don’t feel constrained to making rolls, +1 bonuses, and swapping stats. Since all moves flow from the fiction, a fictional effect like “They treat you as a friend” is just as powerful and useful as +1 forward—maybe more so.

Here are some broad types of effects, any given move may use more than one of them:

  • Roll. Examples: Defy Danger, Cast a Spell (Wizard), Called Shot (Ranger).
  • Substitute stats. Examples: Dwarf (Fighter).
  • Negate damage. Examples: Man's Best Friend (Ranger).
  • Give a bonus or penalty, forward or ongoing. Examples: Underdog (Thief), Smite (Paladin).
  • Deal or heal damage. Examples: Volley, Backstab (Thief), Arcane Art (Bard).
  • Choose options. Examples: Spout Lore, Discern Realities, Ritual (Wizard).
  • Hold & Spend. Examples: Dominate (Wizard spell), Trap Expert (Thief).
  • Ask & Answer. Examples: Charming and Open (Bard), Spout Lore.
  • Change circumstances. Examples: Reputation (Bard).
  • Mark experience. Examples: End of Session.
  • Call for more information. Examples: Parley, Ritual (Wizard).
  • Add options. Examples: Called Shot (Ranger).

Changing the Basics

Moves can also change the basic structure of the game. Consider this one, to avoid the use of damage dice:

When you would deal damage, instead of rolling the dice, substitute each dice with the listed number. d4 becomes 2, d6 becomes 3, d8 becomes 4, d10 becomes 5, d12 becomes 6.

Moves like this change one of the basic features of the game. Be very careful with moves that muck with the fundamentals. Moves should never contradict the GM’s principles or agenda, or break the basic “take the action to gain the effect” rule.

There are some parts of the game that are exceptionally easy to change. The amount of XP to level reflects our view, but you can easily make leveling more or less rare. As well, the kinds of things players are awarded XP for can be easily changed—if your game isn’t about exploring, fighting monsters and finding treasure, change the End of Session move to reflect that difference. Make sure to share it with your players before you start the game.

Another basic that’s occasionally asked for is a way to make, say, fighting a dragon harder. The best answer here is that fighting a dragon is harder because the dragon is fictionally stronger. Just stabbing a dragon with a normal blade isn’t hack and slash because a typical blade can’t hurt it. If, however, that isn’t enough, consider this move from Vincent Baker, originally from Apocalypse World (reworded slightly to match Dungeon World rules):

When a player makes a move and the GM judges it especially difficult, the player takes -1 to the roll. When a player’s character makes a move and the GM judges it clearly beyond them, the player takes -2 to the roll.

The problem with this move is that the move no longer reflects anything concrete. Instead, the move is a prompt for the GM to make judgment calls with no clear framework. If you find yourself writing this custom move, consider what difficulty you’re really trying to capture and make a custom move for that instead. That said, this is a valid custom move, if you feel it’s needed.

Development of a Move

Let’s look at how one move developed over time. Hack and slash was one of the earliest Dungeon World moves, originally written by Tony Dowler. The first version looked like this (this version has been reformatted and edited for grammar only):

When you wade into combat, attacking your enemies, deal damage to the enemy you’re attacking, take that enemy’s damage, and roll+Str. ✴On a 10+, choose 2. ✴On a 7–9 choose 1.

  • Prevent one ally from taking damage this round
  • Kill one enemy of lower level than you or deal max damage to otherwise
  • Put an enemy right where you want them (drive them off, prevent them from fleeing, etc.)
  • Divide your damage amongst any number of targets you can reach with your weapon

The first problem with this move is that one of the options, preventing damage, is far less useful than the others. Being able to outright kill an enemy is nearly always better than preventing that enemy from doing damage. The first major revision was to drop that option:

When you wade into combat, attacking your enemies, deal damage to the enemy you’re attacking, take that enemy’s damage, and roll+Str. ✴On a 10+ choose 2. ✴On a 7–9 choose 1.

  • Kill one enemy of lower level than you or deal max damage to otherwise
  • Put an enemy right where you want them (drive them off, prevent them from fleeing, etc.)
  • Divide your damage amongst any number of targets you can reach with your weapon

This left only three options which is a great number of options to have when a 10+ lets you pick two. The player making the move always had to not choose one option. All of the options are also clearly useful. But there’s still an issue, easily the biggest issue with this move: the fictional action doesn’t tightly relate to the outcome.

Consider this situation: Gregor attacks an eagle lord with his mighty axe. He describes his fictional action: “I swing my axe right down on his wing with a big overhead chop.” Then he rolls the move, gets a 10, and makes his choices. Max damage is a clear choice and comes right from the fiction. The other options, however, don’t make much sense. If he chooses to divide his damage, how does that flow from his one fictional attack? How did that one chop also hit the treant behind him?

Scoping down the fictional effect of the move lead to this version:

When you attack an enemy who can defend themselves, roll+Str. ✴On a 10+, you deal your damage but your enemy does not get to deal theirs to you. If you choose, you can take your enemy’s damage and deal double damage to the enemy. ✴On a 7–9, you take the enemy’s damage and deal your damage.

Here the move now has only the effects that could clearly follow from a single attack. Any action that couldn’t reasonably lead to a counterattack isn’t hack and slash, so now the trigger matches the effects. Unfortunately double damage was a bit much, so we changed it to this:

When you attack an enemy in melee, roll+Str. ✴On a 7–9, you deal your damage to the enemy and take their damage. ✴On a 10+ you deal your damage to the enemy. You can choose to also take the enemy’s damage to deal +2 damage.

+2 damage is a clear advantage, but not a game breaker. The only problem here is that it reduced the effects of an attack to taking damage. Monsters do so much more than just take away your HP; monsters hurl you about the room and destroy the ground you stand on, why can’t they do that in response?

When you attack an enemy in melee, roll+Str. ✴On a 10+, you deal your damage to the enemy and avoid their attack. At your option, you may choose to do +1d6 damage but expose yourself to the enemy’s attack. ✴On a 7–9, you deal your damage to the enemy and the enemy makes an attack against you.

This version (the final one) allows a monster to “attack” not just deal damage. That opens up a whole host of interesting monster moves to be used. +1d6 damage instead of +2 makes the choice more exciting (and slightly more powerful). The rewording adds clarity.

The GM

Changing the GM’s side of the rules is an entirely different beast from writing custom player moves. Writing GM moves is the easy part. Since a GM move is just a statement of something that fictionally happens, feel free to write new ones as you please. Most of the time you’ll find they’re just specific cases of one of the moves already established, but occasionally you’ll come across something new. Just keep in mind the spectrum of hard to soft moves, your principles, and your agenda, and you’ll be fine.

Changing the GM’s agenda or principles is one of the biggest changes you can make to the game. Changing these areas will likely require changes throughout the rest of the game, plus playtesting to nail it all down.

Play to find out what happens is the least changeable part of the GM’s agenda. Other options, like “play towards your set plot” or “play to challenge the players’ skills” will be resisted pretty strongly by the other rules. The moves give the players abilities that can change the course of an planned adventure quite quickly; if you’re not playing to find out what happens you’ll have to resist the moves at every step or rewrite many of them.

Fill the characters’ lives with adventure could be rephrased, but it’s hard to really change. “Fill the characters’ lives with intrigue” might work, but intrigue just seems like a type of adventure. Removing this agenda entirely will require major reworking since the move structure is based on this. The effects of a miss and the GM’s soft moves are all there to create a life of adventure.

Portraying a fantastic world is maybe the easiest to change but it still requires considerable rewriting of the class moves. A historical world, a grim world, or a utopian world are all possible, but you’ll need to carefully rethink many moves. A historical world will require magic, equipment, and several other sections to be nearly entirely rewritten or removed. A grim world can only survive if the players’ moves come with darker costs. A utopian world won’t need many of the moves as written. Still, this is the easiest part of the agenda to change, since it requires changing the moves, not the basic structures of the game.

The GM’s principles are more mutable than the agenda but still can seriously change the game with only minor modifications. Address the characters, not the players; Make your move, but misdirect; Never speak the name of your move; Begin and end with the fiction; and Be a fan of the characters are the most important principles. Without these the conversation of play and the use of moves is likely to break down.

Embrace the fantastic; Give every monster life; Name every person; Think Dangerous; and Give them something to work towards are key to the spirit of Dungeon World and fantasy exploration. These are changeable, but they amount to changing the setting of the game. If you want to change any of these, you may have to make changes to all of them.

Leave Blanks; Sometimes, let them decide; and Ask questions and use the answers are important to running Dungeon World well. They also apply to many other games in the same style. The game will be diminished without them, but the conversation of play will continue. These are also some of the most portable principles, applicable to many other games. They may even work in games with very different play styles.

An additional principle that some people prefer to add is Test their bonds. This principle is entirely compatible with the others and with all the moves, but it changes the focus of the game somewhat. Fronts need to be rethought to work fully with this, and you might need to add moves that speak to it.


The easiest place to modify monsters is in the questions used to create them. The simplest changes have to do with adjusting lethality or randomness to your liking.

A more interesting change is to change the questions being asked to present a different view of monsters. The views built into the questions imply that monsters are more or less like other creatures: they can be of many alignments and won’t always be opposed to the player characters. If you want to make Dungeon World about hunting down evil monsters and destroying them, you might rewrite some of the questions, maybe adding this:

The monster is Evil through and through. Choose one to reflect why it’s evil:

  • It’s an intrusion of the Old Ones Beyond the Walls: Planar, +5 damage
  • It’s a product of the Old Wizards of the Red Tower: Construct, +5 HP
  • It’s from The Time Before Man: Primordial, +5 damage, +5 HP

When creating new monster questions you can either reinterpret existing monsters by answering the questions for them again or only use the new questions for new monsters. If the new questions you add or change are key to your vision of Dungeon World it’s best to redo all the monsters you use; if the question only applies to a specific kind of monster anyway you can just use it for new monsters.
