Flexible Counterspell (Su)

Your mythic power enhances your ability to counter spells. As an immediate action, you can expend one use of mythic power to attempt to counter a spell. Upon using this ability, you must identify the spell with a Spellcraft check (DC 15 + the spell's level). If you correctly identify the spell, you can expend a spell or spell slot of a level equal to or higher than the spell being cast to counter the spell.
