Guise of the Coercer
You will need to have a Rogue complete Rogue 1.0 Epic up to the point where they get Sealed Box.
You will also need to kill Stanos Herkanor and loot Head of Stanos. It’s best to have others kill him so your rogue does not lose faction. Depending on the era it might take a few players or up to a group or two to kill him. He summons all the mobs in the cave area when he is attacked (similar to how Cazic-Thule summons Plane of Fear trash upon aggro).
Once you have Sealed Box and Head of Stanos head to Kithicor Forest. Give Sealed Box to one of the Dark Elves at night. This will spawn General V`ghera. Give General V`ghera Head of Stanos to receive Guise of the Coercer. General V`ghera will despawn upon turn-in so only one person can do it at a time.
