Damage
When a character hits with a weapon, he or she deals damage according to the type of weapon. Effects that modify weapon damage also apply to unarmed strikes and the natural physical attack forms of creatures.
Damage is deducted from the target’s current hit points.
Minimum Weapon Damage
If penalties to damage bring the damage result below 1, a hit still deals 1 point of damage.
Strength Bonus
When a character hits with a melee weapon or thrown weapon, add his or her Strength modifier to the damage.
Off-Hand Weapon: When a character deals damage with a weapon in his or her off hand, add only half of the character’s Strength bonus.
Wielding a Weapon Two-Handed: When a character deals damage with a weapon that he or she is wielding two-handed, add 1.5 times the character’s Strength bonus. However, the character doesn’t get this higher Strength bonus when using a light weapon two-handed; in such a case, only the character’s normal Strength bonus applies to the damage roll.
