i use stuhns with alch. honestly not many great variety of sets cuz defense is already bad for stamblade in a traditional sense so all damage and maybe something like eternal hunt for bgs.
balorgh, stuhn's, eternal vigor, master dw. 2 medium, 5 heavy. infused jewelry. (dark cloak). been switching up my build a lot lately since pvp is very lack luster. ive tried stuhns spriggans, nma stuhns, stuhns ward of cyro, it all falls back to not being survivable enough. not enough sustain for more than 3 people or not tanky enough. the game is in a weird spot imo
