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] Otherwise, your attack misses.

Attacks

These are the factors that affect your chance of hitting with any non-spell attack, whether melee or ranged:

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 (or bare hands or martial arts, if you are not two-weaponing.[14]
  • 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.[15]
  • A penalty if riding a steed: −2 if restricted or Unskilled in riding, −1 if Basic, and no penalty if Skilled or better.[16]
  • An additional −2 if you engage in two weapon combat while riding a steed.[17]

Monster characteristics and status

  • The target monster's AC.[18]
  • +2 (cumulative) against a stunned, fleeing, or sleeping monster.[19]
  • +4 against a paralyzed monster.[20]

Monster-specific

Melee

These factors only affect your chance to hit with melee attacks:

Weapon and equipment

Your characteristics and status

  • +1 for all melee attacks.[28]
  • A bonuses based on your strength (see strength table).[29]
  • +1 if you are at experience level 1 or 2.[30]
  • −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.[31]
  • −3 if you are currently trapped.[32]
  • If you are engulfed, you always hit.[33]

Ranged

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

  • −1 for all ranged attacks.[34]
  • The target monster's AC.[35]
  • 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 paralyzed monster.
  • +2 if the item used is a heavy iron ball.
  • +6 if the item used is a boulder.
  • +2 for using a blessed weapon against a demon or undead.[36]
  • +2 for using any spear against a "kebabable" monster: xorns, nagas, dragons, jabberwocks, and giants.[37]
  • +4 for using a trident against any swimmer that is in water.[38]
  • +2 for using a trident against any S or ; that is not in water.
  • +2 for using a pick-axe or dwarvish mattock against a xorn or earth elemental.[39]
  • +1 if you are hitting any orc as an elven hero currently in natural form, or polymorphed into an elven monster.[40]
  • 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 paralyzed, 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 very eroded, or −3 if completely eroded.
  • +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.

Spells

Spells to-hit calculation is quite different. For ray 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.[41]
  • A bonus based on your dexterity (see dexterity table).[42]
  • 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.

Non-ray spells work differently. Force bolt will hit if the roll of a d20 is lower than (10 + target's AC), with no modification for dexterity or skill. Other beam and non-directional spells will always hit, but may be resisted.
