Attack strength

Attack strength (AS) is a numerical value that determines if, and how hard, an attack strikes an opponent.

Factors

Many things factor into how high a character or creature's attack strength is. Stance and training in a weapon skill or skills applicable to the weapon being used have the greatest effect on attack strength. Stats, spells, other skills (such as Combat Maneuvers and Perception), weapon enchantment, low health, low spirit, and having recently pulled muscles due to over-use of stamina also play a rather large effect on a character's attack strength.

Melee

Melee AS =   STR Bonus
           + Weapon Skill Bonus
           + [Combat Maneuvers Ranks / 2]
           + Weapon Enchantment
           + Modifiers

Weapon Skill Bonus uses the appropriate skill for the weapon. Certain hybrid weapons take the average of two separate skills, notably the katana if wielded one-handed (Edged Weapons, Two-Handed Weapons), and the katar (Brawling, Edged Weapons).

Ranged Weapons

Ranged AS =   DEX Bonus
            + Ranged Weapons Skill Bonus
            + [((Perception Ranks - 40) + (Ambush Ranks - 40)) / 4]
            + Weapon Enchantment
            + Modifiers

Perception and Ambush are beneficial above 40 ranks, but are not counted before then (their contributions are never negative).

Weapon Enchantment combines the enchantment level of the bow and arrow (or crossbow and bolt), so a +25 bow with a +25 arrow combine for +50. The benefit is capped at +50, or twice the character level, whichever is lower.

Thrown Weapons

Thrown AS =   [(STR Bonus + DEX Bonus) / 2]
            + Thrown Weapons Skill Bonus
            + [(Perception Ranks + Combat Maneuvers Ranks) / 4]
            + Weapon Enchantment
            + Modifiers

Bolt Spells

Bolt AS =   DEX Bonus
          + Spell Aiming Skill Bonus
          + Modifiers
