Attack strength (AS) is a numerical value that determines if, and how hard, an attack strikes an opponent.
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.
For characters, stance multiplies overall attack strength by a factor between 50% (full defensive) to 100% (full offensive). For creatures, the stance effect on attack is much less pronounced, as it mostly affects their defensive strength.
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 AS = DEX Bonus + Ranged Weapons Skill Bonus + [(Perception Ranks - 40) / 4] + [(Ambush Ranks - 40) / 4] + Weapon Enchantment + Modifiers
Weapon Enchantment is determined by the bonus of the bow. As a result of ranged weapon changes in May 2020, enchant of the arrow or bolt being fired (either from material or spells like Elemental Blade) no longer has an affect on ranged attack strength.
Thrown AS = [(STR Bonus + DEX Bonus) / 2] + Thrown Weapons Skill Bonus + [(Perception Ranks + Combat Maneuvers Ranks) / 4] + Weapon Enchantment + Modifiers
