Pulverize - when enraged, increase maximum health by 30% for 15 seconds.
Unbridled Wrath - Pulverize new maximum health bonus: 35%
So there are 2 similar passives here, both named Pulverize, that give 30% and 35% health bonus respectively.
If you let the ability expire and then use an enraged Pulverize, you get the one that’s currently equipped (like you’d expect). But if you still have a buff running and you use an enraged Pulverize, it refreshes the duration on the already running one.
Practically this means it’s possible to have the 35% health bonus without the passive slotted. Or to get 30% health bonus even with the passive. It’s probably not the easiest thing to do outside of the training dummies but it’s still wrong.
