I've heard of an op build where you do a ton of damage but I don't know how it works. Can someone help me out? Stats, items, good companions, powers, class would be great.
This is the best guide I could find
I might not be the best source but from what my experiences are, (for now) the most powerful build is a spellblade thief, the tweaked one the person who's beat kass at winter palace multiple times, sorry forget his name, made. charge weapon, triple threat, sure shot, eviscerate, unbreakable, c petal and kunai (to apply bleed) then swap kunai for sanctified gladius so you get your passive activated and have more damage output from the gladius. unbreakable to ensure even if your entire party is nuked you live, sennenbari belt for a second chance, and just enough time to do your combo ensures at least the possibility to near one shot anything, and the survivability to do so. just minimal aoe, but besides kass party should be able to do that. ag str and cunning, with drinks if needed. you can also swap around weapons if needed to exploit weaknesses, which circles to original question.
