Kill him in two rotations. Drops calcified fragment, emblem and a 320 artifact :D
Edit 1: Doesn't have to be done in two rotations as long as different people are grabbing the aura. You also get a 320 weapon of some sort to drop as well on hard mode. When we did it no info was available about this. I was trying to help out and get this info out asap.

Edited by Kage Goomba: 12/6/2015 3:28:02 PMit's 2 different people carrying aura...not 2 rotations. (Saw EDIT later lol) Know this because we "stumbled" into it last night..or was it the night before...lol
