I'm at the point where i'm on the 'for my brother' mission where I must defeat Kunkah, but I just can't seem to beat him. I've been playing the game and upgrading my equipment where I can, but I seem to be struggling with that as well. I've been watching a youtube walkthrough but he seems to be doing SO much better and I don't know what I'm doing wrong or differently from him/the guide. I've been buying higher level equipment, but that doesn't do much for me. I can't enchant it because the game wants me to have my class upgrade in order to buy insurance scrolls, but in order to do that I have to do a mission thats even harder than the one I'm currently on.
I really don't understand what I'm doing wrong and could REALLY use some help, please.
