As a Ranger armed with Snare and a good bow, this is one of my all-time favorites! He moves so slowly that I could WALK backwards and drop arrows into him till the sun rose in LFAY. Hehe, local Wood Elf Humor! I found him near the GFay zone just beyond the Gnome huts as I was tracking. Wow was he FUN! 25 Arrows later, he was dead - Again. He never touched me. He exists, but it's rare that he survives long. I raised my Archery 6 points kiting him a couple times. Careful, if Snare breaks early he'll come at you all kinds of pissed off. Stock up on that long range ammo for this guy. He's EASY!!
Wanders all over the zone. Started pounding on me while I was gathering my gear off my corpse at the Nybright sisters' camp. Fortunately it is really slow so I just ran off dragging my corpse along the way.
Found wandering near the GF zone, and aggros on sight(Low level chars hunting wasps etc near then entrance watch out for him). Reeeally slow though and you can easily outrun him without SoW.
Out of all the times I've gone to Lesser Fay I have never seen this mummy before. Nor have I heard anybody shouting in that zone about it. I do not believe that it wanders around the Greater Fay zone because I used to hang around there all the time and never ran in to it once.
