Damage roll

This is the amount of damage that is done after a successful attack roll.

Melee attack and thrown weapons
The damage dealt is equal to the weapon's damage dice, plus the weapon's bonus (+1 to +5), plus any damaging enhancement (like Flaming or Pure Good), plus strength (multiplied by 1.5 if two-handed fighting or 0.5 for your offhand if two-weapon fighting), plus Power Attack (doubled if two-handed fighting), plus any extra damage coming from enhancements and any sneak attack if the character does not have the aggro or if the mob is blinded or helpless.

Ranged attack
The damage dealt is equal to the weapon's damage dice, plus the weapon's bonus (+1 to +5), plus any damaging enhancement (like Flaming or Pure Good), plus strength (only with bow if the character has Bow Strength), plus any extra damage coming from enhancements and any sneak attack if the character does not have the aggro or if the mob is blinded or helpless.
