Elements of a Monster
Every monster has moves that describe its behavior and abilities. Just like the normal GM moves, they’re things that you do when there’s a lull in the action or when the players give you a golden opportunity. As with other GM moves they can be hard or soft depending on the circumstances and the move: a move that’s irreversible and immediate is hard, a move that’s impending or easy to counter is soft.
Each monster has an instinct that describe its goals at a high level. Some monsters live for conquest, or treasure, or simply for blood. The monster’s instinct is the guide to how to use it in the fiction.
The monster’s description is where all its other features come from. The description is how you know what the monster really is, the other elements just reflect the description.
Damage is a measure of how much pain the monster can inflict at once. Just like player damage it’s a die to roll, maybe with some modifiers. A monster deals its damage to another monster or a player whenever it causes them physical harm.
Each monster has tags that describe how it deals damage, including the range(s) of its attacks. When trying to attack something out of its range (too close or too far) the monster’s out of luck, no damage. Any tag that can go on a weapon (like messy or slow) can also go on a monster.
There are special tags that apply only to monsters. These tags, listed below, describe the key attributes of the monster—qualities that describe how big they are and how, if at all, they organize themselves.
A monster’s HP is a measure of how much damage it can take before it dies. Just like players, when a monster takes damage it subtracts that amount from its HP. At 0 HP it’s dead, no last breath.
Some monsters are lucky enough to enjoy armor. It’s just like player armor: when a monster with armor takes damage it subtracts its armor from the damage done.
Special qualities describe innate aspects of the monster that are important to play. These are a guide to the fiction, and therefore the moves. A quality like intangible means just what it says: mundane stuff just passes through it. That means swinging a mundane sword at it isn’t hack and slash, for a start.
Monsters Without Stats
Some creatures operate on a scale so far beyond the mortal that concepts like HP, armor, and damage just do not hold. Some creatures just aren’t dangerous in a fight. These creatures may still cause problems for the players and may even be defeated with clever thinking and enough preparation.
If a creature is of such a scale far beyond the players, or if it just doesn’t put up a physical fight, don’t assign it HP, damage, or armor. You can still use the monster creation rules to give it tags. The core of a stat-less monster is its instinct and moves; you can have it make its moves and act according to its instinct even without numeric stats.
