Magical Aptitude (Mythic)
Your understanding of the principles and intricacies of magic goes far beyond your training.
Prerequisite: Magical Aptitude.
Benefit: The bonus on Spellcraft and Use Magic Device skill checks from Magical Aptitude increases by 2. In addition, you can expend one use of mythic power to treat a Spellcraft or Use Magic Device check as if you had rolled a natural 20. You must decide to use this ability before making the roll.
