Use the internal dmg proc relic, not the kinetic one as kinetic is effected by armor.
I am doing more dmg with kinetic relic (218 min hit , 443 crit) than the internal relic (210). As an arsenal merc my 35% arm pen benefits me enough to give me higher dmg even with armor. And that test was done on dreadtooth with a 4 stack in corrupted form. I'm just wondering if some math wiz out there can check my numbers and see if the static power + proc makes up for the 66 power loss from the relic?
My gut tells me as an arsenal merc to just stick with using WH relic + DG relic of boundless ages w/ its on use power boost, but I just want to be sure.
