Anima is a derived attribute calculated by adding together Mind and Spirit, dividing the sum by two, and then rounding up (usually, rounding is downward for calculating derived attributes). Anima stipulates the size of a dice pool used for invoking a spirit's intervention.

Body and Spirit are in heightened synergy while one is sharphened, bringing into focus a derived attribute called Forte; Forte is to Body & Spirit what Anima is to Spirit & Mind. But whereas Anima comes into play when invoking the Spirits, Forte is the Body and Spirit jointly supporting and then launching the Mind into a refined trajectory, into an altitude of awareness where it can perceive many things usually beyond its grasp. Forte is the average of Body and Spirit, rounded down.
