Surprisingly there haven't been any darkened clean versions of the Archmage Robes made yet so I figured I'd give it a shot.

Changed textures from 1024robe/512hood to 4096robe/2048hood. Touched up, darkened the feathers, and added texture to each part individually.

Made an Enhanced Darkened version, and an Enhanced Darkened Black/White version.
