How funny that you named in like this, look at how i called mine
And good thinking on Korba, i totally overlooked it when i built mine, and made it around PS conduit. As a result it had insane dmg with PS but it was dying too often because you need to chagre Savagery which makes everything inconsistent.
So i just tried Korba on my build and broke my personal 150-170 3+1 record at 5:50 min! Not sure how that happened, didn’t look at the mutators. Here is the spec in case you wanna give this rendition a go: https://www.grimtools.com/calc/4VxlA8eV
You need a higher slow roll on boots and a slow craft on the helm. Didn’t take RoS cause it’s just +1 button to press. I think trash dies to rings+relic procs and boosted aura.
Edit: I think Thunderous Strike sucks period. It sucks in the same manner on full Rotgeist btw. It only works on Ultos - just because Ultos is built for it. TS really needs some help and the easiest way to buff it is to increase Savagery charge decay to 4 sec.
I’m not actually sure if it’s a problem of TS as it is very powerful itself or a problem of other damage types and builds like 2H melee vitality. But the idea to increase the stacks’ duration is great, imo.
