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)
1 to 3
Or it could be a follow up upgrade from that, your idea first, then my idea , because time stopping is a lot more powerful
taht means it would only také 4 seconds...
