How about a feature that allows you to spend all 4 energy bars to stop time for 5 seconds, enough time to escape an incoming hammer strike and do some damage. When you stop time, all enemies will stop and you will be able to move. 2 down sides include that all weapons will be active to the touch and it takes your full energy bar (doesnt regenerate while time is stopped)

Ooh yes, time freezing is a common suggestion and I like your detailed imagining of how it would work and description of the pros/cons! We might do it some day!
