There is currently no point in killing this guy. He doesn't drop anything and only gave me 700 xp. He's not even part of the Gorgrond rare elite hunter achievement.

His knock back has no range, it seems, so even if you are 40 yards away it will affect you.
Has a "Smash" stacking debuff that reduces healing by 50% and has 15 or 20 second duration, meaning it's difficult to get rid of. If you're a melee class that relies on self healing, this is a difficult fight and there's currently no point.

This roster comes from the current game client's data files, so it is not a complete list of every NPC in the game - older world NPCs that are no longer in the modern client are absent.
