I've added a new rank 9 effect component named Discarnate. This is your traditional Spirit / Mist / Shadow / Wifty Form effect that renders a creature immune to pretty much anything but takes them out of combat at the same time. Before everyone jumps on it, I've already taken the liberty of adding Astral Form to disciples, Shadow Form to warlocks and Mist Form to wizards.
There are a few key things to note about Discarnate. It works a lot like Vanish, except that you are immune to all weapon- and packet-delivered damage and effects instead of being invisible. The only action that you can do while Discarnated, common or special, is moving; anything else will automatically drop the effect, as will a Revert. Also note the distinction that you're only immune to weapon- and packet-delivered damage and effects. This means you are affected by area actions (including the humble melee radius) normally.
Given the similarities Discarnate shares with Vanish, and because a lot of other components are stacked on rank 10, I've also elected to lower Vanish to a rank 9. This should make 9th level a little more interesting, since there's already Slays and Revives to look forward to at level 10.
