This 10-page bolt-on is a self-contained system to provide GMÕs with a way of measuring the ability of Occult & Mythos orientated NPCs to strike-back against characters Ð and the scale of severity of the revenge; it also allows GMÕs to quantify the motivation of the NPC to do so. It contains lists of revenge options from kidnap and sacrifice; to Conjuring non-human entities to capture and kill; through to massive manifestations of Mythos horror.
