So, for the Spellsword, would it be for move action to store, the attack that delivers, or even both? I assume the move action, right?Depends on the ability. A Duskblade does not because it says it doesn't (also, because its a SU ability and SU abilities never provoke). A Spellsword does because its a SP ability, and SP abilities provoke AoOs. Casting a Smiting Spell would provoke because it is casting a spell. I can't think of any other Arcane Channeling abilities, but for reference, consult the list of Special Abilities.
