"I don't know what hunter came up with this one, but it's brilliant."
Potion, rare, cursed
This enchanted blood wine was created recently by a group of vampire hunters. Made from blood freely given by saints and celestials it is the bane of the undead. While it appears to be enchanted much like a traditional pale ale, Vampire Slayer is actually infused with positive energy and masked with enchantment magic. Any undead creature drinking vampire slayer must make a DC 20 constitution saving throw or take 6d6 radiant damage (half on a successful save).
Curse: Vampire Slayer looks, smells, and tastes like an especially delicious blood wine made from a rare blood type.
