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
- The natural to-hit bonus of the weapon.[2]
- A bonus (or penalty) equal to the weapon's enchantment.[3]
- The artifact's to-hit bonus, if using an artifact weapon against an appropriate target.[4]
- A bonus equal to the enchantment level(s) of any rings of increase accuracy you are wearing.[5]
- −20 if you are a Monk wearing body armor.[6]
- If you are a Monk not wearing body armor or a shield, and not wielding any item, +(experience level / 3)+2.[7]
Your characteristics and status
- +1 for all melee attacks.[8]
- Bonuses based on your strength and dexterity (see strength table and dexterity table).[9]
- A bonus equal to your Luck.[10]
- 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.[11]
- +1 if you are at experience level 1 or 2.[12]
- −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.[13]
- −3 if you are currently trapped.[14]
- If you are engulfed, you always hit.[15]
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.[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]
- A penalty if riding a steed: −2 if restricted or Unskilled in riding, −1 if Basic, and no penalty if Skilled or better.[18]
- An additional −2 if you engage in two weapon combat while riding a steed.[19]
Monster characteristics and status
- The target monster's AC.[20]
- +2 (cumulative) against a stunned, fleeing, or sleeping monster.[21]
- +4 against a paralyzed monster.[22]
Monster-specific
- +2 for using a blessed weapon against a demon or undead.[23]
- +2 for using any spear against a "kebabable" monster: xorns, nagas, dragons, jabberwocks, and giants.[24]
- +4 for using a trident against any swimmer that is in water.[25]
- +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.[26]
- +1 if you are hitting any orc as an elven hero currently in natural form, or polymorphed into an elven monster.[27]
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.[28]
- The target monster's AC.[29]
- A bonus based on your dexterity.
- A bonus equal to your Luck.[30]
- 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.[31]
- 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.[32]
- +2 for using any spear against a "kebabable" monster: xorns, nagas, dragons, jabberwocks, and giants.[33]
- +4 for using a trident against any swimmer that is in water.[34]

- +1 if you are hitting any orc as an elven hero currently in natural form, or polymorphed into an elven monster.[36]
- 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.[37]
- A bonus based on your dexterity (see dexterity table).[38]
- 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.
