Kilk

A beverage created by god himself. Consists of a glass of milk and 2-4 drops of ketchup.
Drinking it as a mortal will result in certain death; If you somehow got kilk in your organism — isolate yourself immediately, for you are about to go insane and get your brains melted.

L: Now drink kilk and the ritual will be done.
K: Thats not a good idea, kilk is actually toxic.
L: Even better.
K: Yeah, the mixture is melting his flesh as we speak.
