Willpower (abbreviated as "WP") is the measure of a character's mental toughness and ability to resist mental influences. It controls the availability of spells and determines a character's aptitude for haggling, as well as his or her resistance to the effects of certain spells and skills.
A strong will allows a character to ignore some small measure of suffering, be it physical damage or sheer exhaustion.
Willpower affects a few secondary stats:
- Hit Points: each point spent on willpower grants the character +1 max HP.
- Fatigue: each point of willpower grants a +1 max fatigue.
With a willpower of 20 or higher, a character becomes immune to any spell resisted by willpower.
