Sometimes the Power Cycler simply doesn’t work, I don’t know why.
Nevermind, explained.
I’m pretty sure getting hit interrupts chains.
But I didn’t get hit?
I see red hitmarkers at 17:21 and 17:25 where you linked? Those are when the enemies got a shot in lol. Your own footage doesn’t lie. It doesn’t feel like it because Veteran gets the 50+ toughness back from a swing with his base regeneration + horde + power sword.
