What if you can't kill him, lol? - You die and you have to fight other Tzhaar IN the fight cave, not just random Tzhaar. What if you crap out halfway through the task, is it ok to just kill regular TzHaars? - See last answer. Could I walk into the Fight Caves and just kill up until I die, then respawn and do the same thing until I'm done? - Aslong as you kill them IN the fight caves, yes. (p.s.: don't bother to speculate about the aspects of failing - we can only take info from people who ACTUALLY failed in the game. Thanks.) - I failed on Jad (missed a prayer lol). Its just like any other dead there. No special messages, no Kuradel starting to talk. You just have to get into the Fight Caves again to kill the last ~9 Tzhaar.
