When you attack a creature's body, you reduce its HEALTH
score. When you attack its mind, you instead reduce its RESOLVE score.
RESOLVE is an optional rule which covers not just horror, but all forms of mental and social conflict. Mental damage is applied to a creature's RESOLVE score, as are the verbal
thrusts and parry of social combat. The RESOLVE score is reduced - just like HEALTH -
and when it reaches zero the target is overwhelmed and is no longer able to act.
