GATE!! Yay for Gating mobs!! Translocation anchor on my wiz didn't work long enough to hold this thing down and unfortunately I couldn't blaze him either. Easy mob, boxed 3 toons clr/sk/wiz and my wife played her ranger. Fight went fast down to 20% at which point he gated...summoned the clr...then the wiz...then the rngr...so needless to say we didn't quite kill him. Max hit on 13.7k/2.3k SK was around 1100. Unslowed it didn't even hit fast enough to necessitate chain ch's. Hope the this info helps out =)
Gated! Was not aware of this till WTF where did she go? Summoned the warrior then the cler then the druid to the site where the crystals stick out of the ground... Rez / Med then re-engage the same spot where we died. Mob gated but did not go far. Finally killed it. Maxed hit on 75 warrior 20K / ~3K around 600. Droped the fable and regular neck piece, 8 spells, a quest book. Hope it help some. sorry.. did not have the location but was close to mid east wall.
