Planning a run for this tonight with Alira and Kolob and myself. Just posting on here to see if anyone is interested in getting him as an avatar. Details of what is required to fight him are found at the following link
Since he can be rather tough (and not soloable by a RDM in general) it would be advised that only those with level 70+ jobs come along. Hopefully in the future we can do this again for those that can't go this time.
