Power Points are the number of points any particular character has to use to create the Powers and abilities of the character.
Each character Focus has a different ratio of Power Points that will be available for that particular character. Balanced characters have the most Power Points, but their maximum they can use per Power is the lowest. Focused characters have a medium amount of Power Points, their maximum they can use per Power is in the mid range. Devoted characters have the fewest Power Points, but their maximum they can use per Power is the highest.
Power Points can be further modified through character Traits, Specialties, Atomic Items, and even special GM modifications to a character.
