Strength - Stamina
The Stamina sub-ability score determines muscle efficiency. A character with a Stamina score higher than his Muscle score may not have masses of huge muscles, but the muscles he has will be rock hard. Characters like these may surprise others—not because they can lift four hay bales at once, but because they can lift one or two at a time for 10 hours straight.
Weight Allowance: This is the weight in pounds a character can carry without being encumbered (see Encumbrance Charts for more information). Characters carrying less than or equal to their weight allowance move at their full normal speed.
