With how party members no longer have their stats scale with levels, the Rulwe becomes the unquestionably strongest character once you grab the Dicktacles of Growth, lmao. End of Act 1 and he's hitting for 200~ damage normal attacks, just add the Mark that gives line AoEs to him and go to town. Have to wonder if they forgot that equip existed.
Obviously you can still scale the MC to comical levels with stat boosting items, but it's gonna be a lot slower since you have to invest your gold into the castle, brothel upgrades, and opening cores first.
