Hes 60ish, 61 or 63. Just because hes that high doesnt mean you cant kill him. Right now he is a Melee event, which means all them wizzys get **** to do but **** him off.
He was killed on povar last weekend I believe.
This Efreeti Lord is essentially immune to all magical attacks, combined with his formidable melee attacks he is one of the strongest foes in all of Norrath. His many drops are items of incredible power.
Respawn is 3 days, plus a few hours variance. The death of Noble Dojorn will cause Overseer of Air to immediately spawn.
