Sylvanas-like set

[Vephriel]

Also, just as a note, there's the Windrunner's Bow that drops from Sylvanas in End Time. Though it's not an exact replica of the bow she uses, it could certainly work as the ranged weapon in a set.

I have yet to see her drop that. x_x Things like that make me wonder if it exists. (Not really, but a little.)

[Vephriel]

Oh, I got it on my first run and it's now stashed in my bank since Sylvanas is my <3.

[Kalliope]

Yay! <3

Figures she'd drop it for you, hehehehehehe!
