True Archmage (Ex)

At 10th tier, whenever you cast an arcane spell that targets one or more non-mythic creatures, each of those creatures must roll any saving throws against the spell twice and take the lower result. You gain spell resistance equal to 15 + your highest arcane caster level, but only against arcane spells. Once per round when your spell resistance protects you from a spell cast by an enemy mythic creature, you regain one use of mythic power.
