At 10th tier, whenever you or an ally within 30 feet rolls an initiative check, roll twice and take either result. If the first round of combat is a surprise round, you and all allies within 30 feet at the start of the combat can take a full round's worth of actions instead of just a move or standard action. Once per round, when you or an ally within 30 feet scores a critical hit against a mythic creature, you regain one use of mythic power.
