I can't set a custom time dilation on a ball pawn

Heya, Im trying to add a slow time ability to my game, here is the blueprint for the ability:

and here is the event tick:

I’ve tried just setting custom time dilation to 10, and i’ve tried ‘Get real time seconds’ none of which worked.

my character is a pawn, and they are a physics based ball, if that helps.

Can anyone help me??

physics can run only 2x faster by default I think, it’s limited by MaxPhysicsDeltaTime but if you increase it then physics just explode with increased time dilation
