Raw Human Meat

Outside Halloween, nobody plans around it. Harvest a dead player and the body hands you raw human meat along with the rest. Eaten as it is, its own text says it damages your health, and even as cooked human meat it stays last-resort food that leaves you thirsty. Most of the year it is the stack you drop.

The Halloween event flips that. Every monster part for the Frankenstein table has it in the recipe: three pieces for a light or medium part such as the light Frankenstein torso, six for a heavy one like the heavy Frankenstein head. A whole light monster costs nine, a whole heavy one eighteen, and that is before the animal fat and bone fragments.

So during the event a fight ends differently. Your group holds off a raid at dusk, four bodies lie outside the wall, and instead of only grabbing the guns, someone goes round with a knife. One good defence becomes the start of a monster.
