Improved Unarmed Strike (Mythic)
Your unarmed strikes are more powerful than others.
Prerequisite: Improved Unarmed Strike.
Benefit: You can add half your tier to your damage with unarmed strikes. As a swift action, you can expend one use of mythic power to overcome the hardness of objects with your unarmed strikes. This effect last for a number of rounds equal to your tier. If an object’s hardness is greater than 15, you don’t ignore any of its hardness.
