Man, this guy's a freaking psycho!!! I defeated all his minions including the purple dragon and I've gotten Abazigal down to near death like 4 times (in single load btw) yet the b*tch won't die!
In frustration I Ctrl-Y'd him (I was going to reload and try again from scratch AFTER !@#$%^ him but even ctrl-y doesn't kill him!! What gives?? Is this a bug or is he supposed to talk a bit before he dies? meaning something happened to stuff up his dialogue??

I've defeat him like 3 times but that was the original version, not the improved...so?? Arrgh

I dont know if this will help but when i Clua consoled him into my team he was wearing ' imoens belt ' which mean he cant be killed.
