How does iron jaws actually work?
Is it that it simply resetc the timers of wb and vb to maximum as in the descriptiom. Or does it simply reapply both debuffs?

So if for example I toss out a fully buffed vb and wb on a boss and use iron jaws to keep it up for the duration of an encounter would it retain its increased potency? Or would it be overwritten by a weaker version when I used iron jaws?
