When attacking a monster, you must make a successful to-hit roll 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

Skills

  • A bonus or penalty from -4 to +3 (see table), depending on your skill with the wielded weapon, if you are not two-weaponing.[16]
  • A penalty from -9 to -3 (see table), depending on your two weapon combat skill (or your weapon skill, if it is lower), if you are two-weaponing.[17]
  • No bonus for bare hands or martial arts skill.[18]
  • A penalty if riding a steed: -2 if restricted or unskilled in riding, -1 if basic, and no penalty if skilled or better.[19]
  • An additional -2 if you engage in two weapon combat while riding a steed.[20]

Monster characteristics and status

  • The target monster's AC.[21]
  • +2 (cumulative) against a stunned, fleeing, or sleeping monster.[22]
  • +4 against a paralysed monster.[23]

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.[29]
  • A bonus equal to the enchantment level(s) of any rings of increase accuracy you are wearing.[30]
  • The target monster's AC.[31]
  • A bonus based on your dexterity.
  • A bonus equal to your Luck.[32]
  • A bonus equal to your experience level, if you are in your natural form.
  • A bonus equal to your monster level (hit dice) if you are polymorphed.[33]
  • 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.
  • A bonus or penalty from -2 to +5 (see table), depending on the size of the target monster.
  • +2 against a sleeping monster.
  • +4 against a paralysed monster.
  • +2 if the item used is a heavy iron ball.
  • +6 if the item used is a boulder.
  • A bonus (or penalty) equal to the weapon's enchantment, if using a weapon.
  • The natural to-hit bonus of the item, if it is a weapon or gem.
  • +2 for using a blessed weapon against a demon or undead.[34]
  • +2 for using any spear against a "kebabable" monster: xorns, nagas, dragons, jabberwocks, and giants.[35]
  • +4 for using a trident against any swimmer that is in water.[36]
  • +2 for using a trident against any S or ; that is not in water.
  • +2 for using a pick-axe or mattock against a xorn or earth elemental.[37]
  • The artifact's to-hit bonus, if using an artifact weapon (or artifact gem) against an appropriate target.[38]
  • +1 if you are hitting any orc as an elven hero currently in natural form, or polymorphed into an elven monster.[39]
  • If you throw any gem at a unicorn, it will always be caught.
  • If you throw your quest artifact at your quest leader, and he/she is peaceful and not paralysed, it will be caught and returned to you.
  • -4 if you throw ammo without wielding the appropriate launcher.
  • A bonus (or penalty) equal to the enchantment of your launcher, if firing ammo from it.
  • A penalty based on the erosion of your launcher, if firing ammo from it: -1 if eroded, -2 if thoroughly eroded, or -3 if completely eroded.
  • The artifact's to-hit bonus, if firing appropriate ammo from an artifact launcher, against an appropriate target.
  • +1 if you are an elf or Samurai firing any arrows from any bow.
  • An additional +1 if you are an elf firing elven arrows from an elven bow.
  • An additional +1 if you are a Samurai firing ya from a yumi.
  • +4 if throwing or kicking a boomerang.
  • +2 if throwing or kicking an item that counts as a throwing weapon.
  • -2 if throwing or kicking an item that is neither a throwing weapon nor ammo.
  • A bonus or penalty from -4 to +3 (see table), depending on your skill with the thrown item, unless you throw ammo without wielding the appropriate launcher.

Spells

Spells to-hit calculation is quite different. In spells, your to-hit bonus must exceed the result of 4 minus 1d20.

The calculation of the to-hit bonus is simple:

  • A bonus or penalty from -4 to +3 (see table), depending on your skill with the spell school.[40]
  • A bonus based on your dexterity (see dexterity table).[41]
  • If the monster's AC is non-negative, add the monster's AC.
  • If the monster's AC is negative add a random number between -1 and its AC.
