Willpower
Alternate Names: Mental Fortitude, Mind, Spirit
Skills: Meditation, «Creative Ability», Meditation, Theurgy
A character’s Willpower represents his ability to withstand mental attacks, whether they come from situational pressures, like stress, or direct assault, like magical or psychic phenomena.
Spirit
Although Spirit is an alternate name for Willpower, there is evidence in Chapter 4 that its a wholly different attribute instead. The entry for Meditiation suggests perhaps it was once the basis for a character’s mental (or Psionic) powers. The entry for Theurgy suggests it is the Magic basis for identifying spells as they are cast. The Performer profession suggests it might be the basis for Illusory Magic as a <Creative Ability>.
No Attribute
Willpower can be replaced by the Mettle skill.
