I found this Drow standing in front of a line of 4 undead frogloks (i have seen him have skeletons also) near where Fipok Glubble spawns. He didnt acknowledge my hails and when I sat, his undead aggroed on me. Easy kills for my lvl 12 shaman.. however once the two undead frogloks and two froglok spirits were killed this drow guy states he is going to suck my soul... and nails me with some powerful spells. Does anyone know what quest he is associated with?
He's a necro, so beware newbies when fighting him. Also if you approach him, some mobs will spawn right infront of him. He's not on any faction, he'll try and cast, fear, disease cloud and lifespike. After I killed him I noticed something called a Innothule mushroom on the ground. I don't know what tradeskill its used for, probably baking.
The mushroom has nothing to do with Dven, they spawn at various locations throughout the zone (underwater included) and are used to make essences (for making spiritstones with pottery).
I doubt it's a bug that you can't attack him til you kill off his minions, when you attempt to cast on him it says "You spell did not take hold" which seems to mean that it's scripted in that he be unkillable til you take care of the ghoulish frogloks and trolls (those are the skeles) surrounding him. Am curious as to what his purpose is though.
