The Eldritch Scion archetype in the ACG gets Spell Recall @ 11th level:
Spell Recall(Su): The magus learns to use his arcane pool to recall spells he has already cast. With a swift action he can recall any single magus spell that he has already prepared and cast that day by expending a number of points from his arcane pool equal to the spell's level (minimum 1). The spell is prepared again, just as if it had not been cast.
My question is does this have any affect on the Eldritch Scion since it does not prepare spells or does it regain spell slots instead?
