I don’t see the point of this hammer when I can do exactly the same thing (deal lots of damage to Carapace armor) but in a much safer way and with much more mobility, with a Tac Axe with Shred Blessing, + crit chance, and the Zealot crit Feats.
it’s more like Unyielding and Manic killer weapon.
Thunder hammer Headtaker full stack, Zealot 25lv feat full stack, special+ heavy attack+ult to Plague Ogryn deals almost 25% of its health on Damnation.
Which looks hard to accomplish, but stacking Zealot’s feat and headtaker is easy, head shot is bit difficult.
I really don’t think it’s easy. Headtaker last 3.5 seconds, which means you need to hit the plague Ogryn 5 times first and then immediately attack him with your charged attack, because to power it up and use heavy attack spent at least 2 seconds. I found that blessing really hard to keep up with a thunder hammer than any other weapon.
