Attacking - Attacks are actions that cause damage or manipulate a target. An attack uses at least one hit point to increase the attack power of that attack. Additional hit points can be used to manipulate the opponent (See Action Rules/Manipulation) or increase the damage of some weapons.
Attack Power - The attack power of a hand weapon or thrown weapon is the weapon's power bonus or the character's size - whichever is greater - plus the number of hit points used to increase the damage. The attack power of a bow is the bow's pull bonus.
Target Size - Larger targets are easier to hit, so the encumbrance of a target is added to the roll against the success of any attack against that target, even if the target is not defending or inanimate. A character or object's encumbrance is only applied once for each attack, so if a character is parrying an attack, don't add their encumbrance because the parry bonus already includes encumbrance. (See Characters/Description/Encumbrance.)
Attacking from a Distance - Use the bonus from this table (based on the distance from the attacker to the target) instead of the attacker's encumbrance if it is less than the attacker's encumbrance:
