The hallucinogenic mad cap mushrooms (also called death angels) are popular with
the Goblin tribes of the Worlds Edge Mountains. When consumed before battle, the user slips into a mad, destructive rage.[1a]
The feared cult of Goblin Fanatics use these hallucinogenic mushrooms to drive themselves into a frenzied state.[2a]
Mad Cap mushrooms are cultivated by tribes in the Worlds Edge Mountains. However, they are traded to goblin tribes across the Old World.[3a]
In the Warhammer: General's Compendium, pictures of painted models showcased mad cap as being purple in colouration.
