Mob max hit was 1269 on a Level 66, 1436 AC warrior with 9.7k Hps did ok with shammie spiritual serenity and cleric doing complete heals kept him alive with mage pet and beast lord and shammie pets with Dps worked out was a tuff and very close fight we got him he dropped the Sleeves of stardust nothing else.
Sorry, I mis-remembered which named dropped which item (I had been hunting many of the named mobs in Relic). I submitted this item. It did NOT come from the Soul Storm, it came from a named Scrykin on the first floor. When I see him again and remember the name I will submit it.
Sorry about the confusion (too many new nameds ti hunt heh)
