Soul Molding
From what Evin could understand, this was just something that he should be able to do after some practice, so he wasn't very worried about it. He was more interested in the next part of the scroll.
[When you've collected a certain amount of souls you can try your hand at Molding. By molding your soul, you can basically give it more functions. The end result is called a Soul Mutation (EN). It's similar to the concept of mutating your body with Vital Energy, but not quite… Okay, let's give you an example. After you've played around with your soul for a while, you will develop the power to freely feel it in combat. At that point, you can try adding some extra features to it: you can make your eyesight and hearing better by modifying your soul's ears and eyes. Obviously, this wouldn't show on your actual body, but it will affect your sensory abilities.]
