A 41: Bite of the Werebear, Megaladon Empowerment, and Polymorph (et. all.) all come to mind.
Q 42: When creating an item that casts a spell (i.e. a wand, staff, or scepter), is it possible to create the item that casts a spell modified by metamagic, thus resulting in a higher level spell? I know it's possible to have one cast "at will" so to speak, thus allowing unlimited use, but is there a mechanic for casting with metamagic prepackaged? Also, would it be created as I would use the spell, being an Incantatrix and Metaphysical Spellshaper with Sanctum Spell and Arcane Thesis? Also :
Q 43: Going on the assumption that a Psionic Artificer shares all spell lists, would Initiate of Mystra refluffed be about the best way to represent EMP Sealing on a Psiforged Psionic Artificer? This ties in with the above and with the thread made a while ago about making a Transformer.
