As a swift action, you can expend one use of mythic power to make a melee attack at your highest attack bonus. This is in addition to any other attacks you make this round. When making a sudden attack, you roll twice and take the better result, adding your tier to the attack roll. Damage from this attack bypasses all damage reduction.
