Vault of Glass

Destiny has a new high level raid (I suggest for level 28 and up) that gives you the most bad@$$ rifle in the game, the Vex Mythoclast, raid armors, which when fully upgraded boost your level to 30, and lots of other awesome stuff. I'm crucible grinding now to get legendary armor to be able to do the easy variant of the raid, which can still give you the armors. I highly suggest you do this strike RIGHT NOW before it vanishes into obscurity.
