Offensive bonus (OB) is a bonus which is a rating of a character's ability to land attacks on an enemy and deal damage. Offensive bonus suffers the smallest penalty from Encumbrance due to worn/carried weight compared to Dodge bonus or Parry bonus. A character's naked offensive bonus is a function of their Level and Mood. Offensive bonus is increased through equipping a Weapon and practicing the appropriate Warrior skill for that weapon's class (Rogue skill for Short blades). When wielding a weapon, a character's Strength (Str) affects their offensive bonus.
