Dropped for us of Velktor's Experement.
Very hard mob, he rampages and enrages. We had a solid group, 60 warrior/60 bard/60 cleric/58 shaman/60 wizard/60 Chanter.
Been farming this area for the past few days... so far I've found a second cleric can be pretty helpful. Went today with 2 clerics, wizard, bard, warrior and shaman. Long fight due to no offense, but he dropped.
Bards can mez the crystaline golems. Desroyers and named not. I pulled the mobs (bard). Used lull song and mezzed any adds.
