So haven't played the game in forever and figured I'd give the new content a spin. I could try and look through hundreds of pages and find this answer but I'd rather just ask. What's the most OP build in the current game for the MC? Just want a direction to focus on.
Honestly if you just set the difficulty to Story mode, you can run regular Cait and Brint for pretty much the whole game with no combat trouble. Cait's a good healer, and you can switch Brint to tank if you don't want to do it, or keep him as damage if you do. Etheryn has a better healer set you can unlock during her dungeon, so I usually use that after I get it. The game isn't hard unless you want it to be, so you can just build competently and be fine.
Or if you're a lazy bastard, open the dev console with ctrl+shift+i, and paste this in:
pc.hitPointsMaxMod = 9999999, pc.perks[0].values = [100, 100, 100, 100, 100, 100];
That will give you basically infinite HP and max all your stats at every level, so you basically can't lose.
