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.
If penalties to damage bring the damage result below 1, a hit still deals 1 point of damage.
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.
