Willpower

The Willpower (Will) defense represents your ability to withstand assaults on the mind. Attacks that target Willpower can include charm effects, fear effects, illusions and psychic effects. To calculate your Willpower score, use the better of your Wisdom Accuracy (WisA) and Charisma Accuracy (ChaA). Racial bonuses can be granted to the Willpower defense, as well as flat bonuses granted by Combat Training in “Will”.

In summary, to determine your Willpower defense use the following equation:

Willpower (Will) = 10 + [best of WisA or ChaA] + Will Combat Training + LVLM + Racial Bonus + Miscellaneous Bonuses
