At the start of each scenario, initiate a real-time 60-minute insanity timer. When the insanity timer rings, restart it, and then your character must open the cursed book and read it for 15 minutes of in-game time. Failure to do so results in the permanent loss of one Feat of your choice (except this one) and the whispers growing louder permanently. If your character loses all their Featsor only has this Feat left, they die or descend into permanent incoherent madness.

[[Miracle]] can add 180 minutes to the current insanity timer. [[Faith]] or [[Dark Faith]] add adds 60 minutes.
