- If you send him to Cathedral Ward, he'll start killing NPCs one by one and give you 2-3 Beast Blood Pellets each time. Another NPC is killed whenever you defeat a boss. He'll disappear after there are no other NPCs left, so remember to kill him for his rune at that point.
- Drops the second Beast rune when killed, but will transform into an Abhorrent Beast if attacked three times. Easiest way to kill him is by standing in a doorway he can't fit through and using a Poison Knife

- Strong Beast rune
