Anytime the Cryptic wishes to change the type of creature his bonus applies to though. he does, in fact need to change it as a full round action, correct ?
Yes. Instead of just standing there and switching it, I would expend it on a power (so you're not totally useless that round, I prefer an extended buff) and then regain it again with your move via Psionic Meditation. You do have that feat, right. You should. :)
