EDIT: I've been told that he drops a Gauldar Amulet Fragment when he dies. I cheated to get all the Gauldar Amulet Fragment's earlier in the game (I went to the all items room). Could this mean I can't kill him?
NOTES FROM ANOTHER THREAD FROM ANOTHER FORUM:
I tried to kill it using console commands, targeted it and everything (done it incorrectly last time) and typed kill, it just went to the kneeling animation, regened his health (while still kneeling) I took his health down, then he stood up, was ice-y, then he just stood there for 15 seconds, then started to attack as normal with full health.
What the..?
Also, he isn't essential, I checked.
