Willpower contributes to mutation damage avoidance ("Mind Save"), as well as the per-level skill-caps for Power and ALL mutations (including Alpha Mutations, which equals twice your Willpower).
Increase Willpower if you depend heavily on using, and defending against, mutations.
Can be raised by spending 5 AP.
