EU guild Nihilum scored yet another world first earlier today, killing the Illidari Council. Another kill and another confirmed tier 6 drop, this time the legs. This leaves only the chestpiece, which assuredly will drop from Illidan himself. EU guild Curse followed up relatively quickly, defeating the Council only 3 hours after their first Mother Shahraz kill.

Nihilum's newspost about their kill also features some screenshots of the Illidan encounter.
