[2.3.2.8] Encumbrance is the effect of a character's mass and equipment on their dexterity and coordination. This bonus is added to the character's attack and defense bonuses. To calculate encumbrance, add the character's natural encumbrance to their equipment encumbrance. Equipment encumbrance is 10 times the mass of a character's equipment, divided by the character's mass.
