Achanta's X: Somehow, I think class features that outright cripple you when not constantly doing something are a poor idea.
A total -6 to all saves, skill checks, AC, attack, damage, and a -3 to ability score modifiers is just plain not worth it (better hope you don't have anything reliant on these scores/ability checks, or anything only checked against them once a day). Your carrying capacity is shot, you basically never have max HP, you can't spot anything before it gets to you, you're going to have a hell of a time going first (yay, screwed initiative checks), and if you don't go first you're in the worst position possible.
Also, Fast Healing is now almost never worth it, because it barely ever gets to the point it makes a notable contribution within the fight, and it can't heal you outside of it.
