I just can't kill this guy! He's in the tunnels near the Tower Colony, along with the Nephil Warblade and a colony of nephilim, and I really want that sword. I can kill everyone else, including Chief Bhag'Vrrr, with no problems, I've done most of the quests so far, raised my stats thoughtfully, and am playing on normal difficulty.
Whenever I hit him in melee, I receive the same amount of damage, he continually summons reasonably strong monsters, and worst of all, he rapidly regenerates, so I can't even get close to killing him, and I'm using strong equipment for this part of the game. I've tried fighting him for over an hour, and his abilities never wear off, he never stops summoning creature after creature, and I can't get him past half hp. Is there a trick to beating this guy? It doesn't seem like I'm supposed to come here way later in the game, as his cohorts are pretty weak and the sword isn't THAT amazing.
Just totally frustrating.
