Arcane Mastery (Su): At 20th level, an arcane mage’s control and understanding of magic reach unparalleled heights. Each time you prepare your spells, choose any number of spells you know with duration longer than “instantaneous” and total level equal to or less than your Intelligence modifier. You gain those spells as constant spell-like abilities until the next time you prepare spells. If any of those abilities are dispelled, you may reactivate them as a free action.
