This may seem a little bit crazy. but is it possible this guy can be taken under 2 groups? will have 2 tanks both 20khp, 2clerics over 10k mana, and dps. any advice about this or tactics if it is possible would be nice, before we all wipe on a try. I can't resist a good challenge =)
Spawned while we were in zone, gave a pop up message (like the "You have 15 minutes left on your expedition" message) saying that something powerful was coming out of the wall. We stayed well away. Kessadona form, gold look, very red con, KoS. Didn't attack any mobs in zone.
