Version 0.26: This article may not be up to date for the latest stable release of Crawl.

Willpower (Will) is the ability to resist hostile enchantments such as slow, confusion, banishment to the Abyss, and paralysis.

The higher a being's Will, the less likely that it will be affected by an enchantment cast on it. Beings that are magical in some way (such as elves or sirens), magic-users, and those that are non-natural tend to have higher Will than other creatures.

Monster Will is partly based on hit dice, so monsters with high hit dice tend to be strong-willed. Most monsters with one hit die have a 50% chance to fail to resist outright, in addition to the normal saving throw. Finally, some monsters are outright immune to magical enchantments - for instance, most nonliving creatures.

Resistible Enchantments

Some of these effects can come from potions, weapon brands, clouds, or spells that are not considered enchantments.

Notes

  • Many of these enchantments can be resisted via other means. For example, undead, nonliving, and plant monsters cannot be slept.
  • Polymorph will not be resisted by (very) ugly things, which will always change color. Shapeshifters can only resist it if they are currently in the form of something with infinite will.
  • Effects produced by the chaos brand don't check Will.

Resisting enchantments

Resisting an enchantment is dependent on the resisting creature's Will and the enchantment power (which is a function of the spell power) of the enchantment it is resisting. The formula is:

If 1d100 + 1d101 is less than 102 + Will - the enchantment's power, the enchantment is resisted.

This is sometimes referred to as a "saving throw", after the die-based resistance system employed in Dungeons & Dragons.

Enchantment power is your spell's power multiplied by a modifier (usually 1) and then passed through a stepdown function which halves your spell power every 30 points above 40. Agony, Pain, Slow, Corona, Teleport Other and all the mass enchantments have modifiers greater than 1. Ensorcelled Hibernation has an additional stepdown.

Resistance Descriptions

Neither the player's nor monster's Will is ever given explicitly, but a rough suggestion of how resistant they are can be seen by pressing the % key for the player, and examining a monster's description. The specific number can be calculated, however.

Pluses on these screens correspond to the Will level of the player or monster, as follows:

Pluses shown Player Will Monster Will
..... 0-39 0
+.... 40-79 1-40
++... 80-119 41-80
+++.. 120-159 81-120
++++. 160-199 121-160
+++++ 200 or more 161 or more

As a practical matter, a player who has Will++++ should be able to usually resist the most dangerous enchanters in the game (such as deep elf demonologists, liches and ancient liches). More Will reduces the likelihood of these spells landing even further, but the gains become significantly less important beyond this point.

Player Resistance

Player resistance is determined as below:

Experience level × racial multiplier, plus the following:

Racial multipliers are as follows:

Will per XL Species
7 Spriggan
6 Deep dwarf, Felid, Purple draconian
5 Naga, Vine stalker, Mummy
4 Deep elf, Demigod, Vampire, Formicid, Ogre
3 All other species

History

  • Prior to 0.26, willpower was called magic resistance (MR).
  • Prior to 0.13, Blink Other was subject to magic resistance.
