Took this guy down on Coirnaiv TLP server today, with:
51 pally (hack, bash, heal and taking the hits)
53 druid (dots, and heals)
56 bard (Tash- with journeyman staff, slow, haste and manasong)
Made sure to buff up before fight.
Pally is currently a little shy of 400 ac, and he did hit rather hard, but once slow landed, the pally could pretty much keep him self up.
