Our raid run into that mob thinking it was a standard named one. After killing we realized it was Epic 2.0 mob. We had one Wizard who was only lvl69 but wanted to loot but the advanced loot system locked the item. Happend on King Gelaqua too. 15min+ waiting time. But here on this one the Horn was still locked after the 15min. So it seems it is not prelootable, bad. So don't kill the mob if you are not at the right stage of your Epic 2.0. Wasted mob, wasted time, possibly sad Wizzy who needs him :(
