Was for an expedition. You would go to Neriak and kill trolls and then kill the boss...then run to Nek to turn in. The boss would drop the Trinket of Ancient Fears (the same one from the ring event in Cazic Thule) and then each group member would get a potion. The potions were random, one charge illusion ones, or one charge exp potions or 10 charge greater exp potions which last for 15 minutes and give you double exp.
