Just deleted a 32 Titan with a Gjallarhorn on it, just to go and use the 20 class item engrams I had saved up to get the Frumious Cloak.
Worth. It.

That's what I use. I have Frumious, Brawler and Cloak of Perception. They all look pretty cool. I use Revenant with full crota gear, and it looks pretty amazing.
