Dragging this from the depths to throw in my prediction for reaper starter gear.

There's not a lot of gear with that vibe and I was stumped for a while, but finally I remembered the Void Ark Striking set which is a cool design and I think it would fit well.

My only other maybe-guess was the light DPS Cryptlurker set, but that doesn't have quite the same feel to it.

Also it occurred to me that the Field Commander's coat would be great for sage but it's very unlikely they'd give that away for free.
