This guy spawns on the middle island right from where you zone in from Fungrove in that castle he is not that hard just try to snare him and kite him around if your a wizard Im still working on my Robe quest so I camped this guy he is around a 2 hour spawn time.
There is really no need for pictures of these guys, they all look the same but have the different names above them. So far all the higher lvl ones such as the greater shadows and the named ones I have fought are all light blue to me at lvl 51. which means I have fought no lvl 40 shadows. The only hard thing about them is the stupid life taps, since I am a melee. I only pull the light blue greater shadows since I get xp off them still, and so far have gotten 3 named ones to spawn in a relatively short time, good luck to ya.
I just killed this guy. Its much harder than the greater shadows and must have about 1.5 K HP. Hits for about 100ish. Dropped a Book of Sorcery (must be quest item) that is NOT no drop. Does anyone have an idea what it is for?
