Oh gosh okay, that was quite long and complicated. I will definitely consider getting limit breaker (although I read somewhere that it is literally the penultimate DLC story, so i'll need a lot of work to get there). The weapon idea looks really great tbh, so i'll definitely be using that. I'll be able to afford it since i have 77,000 gold as bullion in my inventory. However, I kind of wanted to finish as a grandmaster so I could use magic, as I really like magic.
However, i'm going to go with the skill set ideas you gave me because they're really good.
