Here the suggestion for ravaging time :

when you are in effect of your spell or manifestation that alter your time like time stop, you can take mythic power for attacking creature in frozen time. Creature in frozen time are considered helpless. You take two mythic power and you can make as swift action, three and make a standard action, four a full round action and five a attack action that recquire a entire round. If your spell or manifestation can permit other creature to move with you like mythic time stop, you can take mythic power for ally for the attack action again ennemis.

A 10 tiers, Each ally can once per days take this own mythic power when you cast or manifest a equivalent of mythic time stop but ONLY this own attack, not ohthers ally attack action.

You can take other item from other creature when you are in ravaging time but take mythic power equivalent for depending of action you make for stealing object for ennemis.
