I got to the third and final Guardian of the Path in Hordes of the Underdark.
But this a-hole is a tough one! He resists all my attacks! I can deal some damage to him with superb weapons, and my animal companion helps a lot, but there's no way I can get him below Injured when he slowly regenerates back and kills my entire crew [Valen, Aribeth, bear and myself].
The only ones who deal any damage to him are me and my bear. I'm really stuck here.
I even tried equipping myself and Valen with ranged weapons, then running back to that remote little piece of land so that he can't reach us while we shoot at him. However, that way we can't get him below...uninjured. :S
I'm a level 26 Half-Elf Ranger with no offensive spells.
Please help, this guy is so imbalanced.
