Ive got a tip k?
Find a training exercise that your really good at. Just do that one not any others. Then you should level up if you do it lots, use your lvl up point things to increase every skill apart from the one you have chosen.
This game is super duper super good! The ONLY thing i think could be improved is the fact that my lil' soul has a really accurate bow to train with but not to fight with...the game is still one of the best games i have ever played!
