The bag is on normal mode meaning it has the following 16 tokens: +1,0,0,-1,-1,-1,-2,-2,-3,-4, Skull, Skull, Cultist, Tablet, Auto Fail, Elder Sign The scenario card for Night of the Zealot on standard turns the skulls into a variable based on the number of ghouls hanging around and the cultist and tablet to -1 and -2 respectively
