Mythic Power Charges (Rank 7)

All Mythic heroes have a reservoir of Mythic energy they can expend to use or empower their abilities.  Although it is an energy source that is hard to come by. 

A Mythic hero can have a number of charges of Mythic power equal to their Mythic rank.  They regain a single charge of Mythic power upon completing a long rest in which they do not also regain a point of exhaustion.

Upon gaining a new mythic rank, the hero's maximum amount of Mythic power increases by 1, but their available Mythic powers will only increase upon a long rest.
