How does a magus use a meta-magic rod.
Does he have to put his weapon down?
Can he hold his sword in one hand and cast the spell with the other then grap the rod as a move and still deliver the spell via spellstrike?
I've been looking into a shield-only skirnir, an unarmed hexcrafter, or a cestus kensai, looking for ways to use a metamagic rod and still be able to use somatic components and spell combat. Normally, they can't.
also glove of storing - cast with rod in offhand while the sword is shrunk into the glove of storing, free action to pop the sword out once done casting. free actions to pull out and put away the sword in any given round, so cast as you like.
