Tainted Bastion has comparable stats to Raiment of Renewal. This is an item that builds easy for supports which provides beef. Tainted Bastion gives gank-survivability. You have little haste early, on top off that you have little mana sustain and in the bank. But... hit your abilities while keeping your mana up will make you a v. annoying support.
