Fundamental/pf

While for the most part fundamentals are identical statistically, they can be divided into four categories, each of which varies slightly. These can generally be thought of as gaseous, liquid, solid, and energetic fundamentals. In addition, each fundamental has the subtype of the elements composing it, and the appropriate home plane for its element. There is no Positive or Negative fundamental.

A fundamental can always see perfectly in its native element. When exposed to their opposing element in any significant quantities, pure or not, fundamentals take one damage per round until removed from that element. Fundamental slam attacks could as the energy type most associated with their native element:

Fire, Magma, Radiance	Fire
Ash, Ice	Cold

Lightning	Electricity
Air	Sonic
Other	None
