Cthulhu

“Rule #1: we don’t talk about Cht… Kth… Clu… The one who can’t be named or spelled properly. No, seriously. Bad memories.”

When Cthulhu spawns, set a dice apart, on its “6” side. Each time Cthulhu activates, the dice result is lowered by 1 point. If the dice result is lowered to 0 before Cthulhu is eliminated, the game is lost.
At any time, all players may decide to inflict 1 Wound to each Survivor. This Wound cannot be avoided, and is only inflicted to Survivors with a dashboard (no Companion, for example). On the other hand, Cthulhu’s dice value is increased by 1 point (max. 6).
