Sonny 2 isn't too bad until Baron Brixius which took me years and some guides to figure out how to beat, and even then it is designed like shit. The literal faggot will heal all the way back to full if you damage him too much while inflicting instakills and debuffs on your party, while you're supossed to kill him with whatever skill you have that reverses healing. You have three trees and I'm not even sure all of them have a skill like that. You have to grind a lot and still figure out how to kill him. Maybe I was just a retarded kid, I dunno, but no part of the main game is as hard as this motherfucker, and he's in the 2nd world/act/location, you stumble into him right away.
