Random Table: Soused Servant of Stormbringer

What happens when a character bearing a sapient Chaos weapon loses control of his or her faculties? Roll 1d8!

1-2: You have sacrificed a small animal—a dog, cat, chicken, etc.
3-5: You have carved bloody runes of Chaos into your own flesh. -1 to Charisma (non-cumulative).
6-7: You have sacrificed a large animal—a cow, horse, etc.
8: You have sacrificed a human being! Add 1 to future rolls on this table (cumulative).

Each time this happens, there’s a chance that this opens the way for some sort of thing to cross the veils of reality from the realms of Chaos. This chance starts at 1%, plus 1% per animal sacrifice or set of flesh-carved runes and 5% per human sacrifice (cumulative).

Don’t play with cursed Chaos artifacts, kids!
