Hey guys. So here's my problem, I'm in the last dungeon(Crystal Tower). I get about 3 minutes away from the last boss...then a yellow dragon appears. Problem being, this yellow dragon is seemingly impossible to kill. According to some walkthroughs Xande has 48k HP, but i dish out 60k damage to this dragon before he kills me. I just can not kill him no matter what i do.. Am i doing something wrong here?
