Abbreviated ST.
In general, a character with normal Strength :
•Can move an object up to 200# (or 100% of their weight)
•Can lift a 100# object to his waist (or 50% weight)
•Can carry up to 50# (or 25% weight)
•Can carry around 20# without penalty (10% weight)
Each additional +1 in Strength doubles these default values. Each -1 in Strength halves the default value.
These are all Moderate tasks. For each 100% increments of these values, the difficulty increases one dice. So if a normal ST character is trying to carry 200#, that adds 3 DD.
Thus, a character with +2 ST can move 300% of his weight, lift 200% of his weight, carry 100% of his weight all as a Medium task, and carry up to 40% of his weight without encumbering penalties.
The system assumes an average human to weigh about 200# - which is generous, but mathematically convenient. Strength will further increase or decrease depending on Size.
