When attacking a monster, you must make a successful to-hit roll in order to actually strike it. To do this, your to-hit bonus must exceed the roll of 1d20.[1]

Melee

These are some of the factors that might affect your chance to hit in melee:

Weapon and equipment

Your characteristics and status

  • +1 for all melee attacks.[7]
  • Bonuses based on your strength and dexterity.[8]
  • A bonus equal to your Luck.[9]
  • A bonus equal to your experience level, if you are in your natural form.
  • A bonus equal to your monster type's "level" if you are polymorphed.[10]
  • +1 if you are at experience level 1 or 2.[11]
  • A bonus or penalty from -4 to +3, depending on your skill with the wielded weapon, if you are not two-weaponing.[12]
  • A penalty from -9 to -3, depending on your two weapon combat skill (or your weapon skill, if it is lower), if you are two-weaponing.[13]
  • A penalty if riding a steed: -2 if restricted or unskilled in riding, -1 if basic, and no penalty if skilled or better.[14]
  • An additional -2 if you engage in two weapon combat while riding a steed.[15]
  • -1 if you are burdened, -3 if you are stressed, or -5 if you are strained; if you are overtaxed or overloaded you will be unable to attack at all.[16]
  • -3 if you are currently trapped.[17]
  • If you are engulfed, you always hit.[18]

Monster characteristics and status

  • The target monster's AC.[19]
  • +2 (cumulative) against a stunned, fleeing, or sleeping monster.[20]
  • +4 against a paralysed monster.[21]

Monster-specific

Ranged

These are some of the factors that might affect your chance to hit when throwing or kicking items, or when applying a polearm:

  • -1 for all ranged attacks.[27]
  • A bonus based on your dexterity.
  • A bonus equal to your Luck.[28]
  • A bonus equal to your experience level, if you are in your natural form.
  • A bonus equal to your monster type's "level" if you are polymorphed.[29]
  • A bonus based on how far away the target is. A target adjacent to you gives a +2 bonus; this decreases by 1 for each move's worth of distance, to a maximum penalty of -4.
  • -2 if you are wielding any bow while wearing gauntlets of power.
  • -3 if you are wielding any bow while wearing gauntlets of fumbling.
