Strength, often abbreviated STR, is one of the core attributes. It is also one of the two which is not directly specified; rather, it is the average of Upper Body Strength and Lower Body Strength. Strength is used in calculations where muscles from the entire character's body are being used, such as climbing a wall. Often, though, a more accurate "weight" for Upper Body Strength and Lower Body Strength than 50%/50% is used for calculations - in such cases, the Strength attribute is not consulted.
