It now grants minor heroism, or an extra ultimate every 1.5 seconds for 9 seconds at level 1. That's 6 ultimate over 9 seconds. I don't know how that changes as Carve levels.
As a sorcerer who likes to use Overload, I wonder if I can use it right before activating Overload, giving me some ultimate regen while it's active?
I also wonder if it can be used outside of combat to generate free ultimate? Does it need to hit an enemy to activate minor heroism? It doesn't say it does.
I still don't know if it's worth taking over Brawler. A damage shield seems more useful than a small amount of ultimate over 9 seconds. The old Carve seemed more useful too. 6 ultimate over 9 seconds for the loss of a damage shield? I'm not sold yet.
