It looks like H is flying off to confront the beast. What are the rest of you doing? Will you make any attempt at arriving near the beast together, or at stealth?
Remember, once combat begins, initiative will alternate between PCs and NPCs. Among PCs, post in any order; you don't have to wait for individual initiatives. If you don't post actions within a few days, your PC will lose its turn, and do nothing; I will not wait more than a few days and I will not choose actions for your PC other than doing nothing.
VR: Schism lasts 17 rounds. It would take you about 2 minutes to fly to the beast, longer if you wait for slower members of the party. At what point do you want H to manifest it?
BTW: Schism is much like 3.0 haste for psions, so maybe I should have banned it (and it should have been revised for 3.5), but for now I'll allow it. True, your manifester level is lower for the second mind, but maybe not by enough. (In H's case, it's 11, but she's multiclassed.) I continue to find psion powers (not necessarily the ones H has) that look very strong to broken to me; I don't understand why many posters seem to think psions are weaker than wizards.
Also, I'll allow Enlarge Person to interact with Polymorph to allow the recipient to use his items, but I'm not sure it's legit, or should be. While a clever tactic - if you thought of it yourself - you'd think that a major limitation of the polymorph spell should not be so easy to bypass. And once it's been done, it becomes merely standard operating procedure for all casters of the spell (PC or NPC) rather than something clever.
