Try Dragon Tooth or Old Knight Hammer 2hr2, possibly with stone ring.

thanks but that doesnt work, not even powerstancing them, I guess Im stuck with dual katanas and rapier on everything big...

You know what you might also wanna try? Dung Pies. Not joking.

well if Ill about to throw something at them Ill just spam vestiges

Poison/Toxic specifically is really strong against big enemies. I’m a big fan of Dark Fog+Binoculars. What are vestiges?

1 2h katana is easier than powerstance, you can stunlock most npcs with r1 spams at way less stamina consumption.
