There is a power called Outer Body Experience that allows the user to make a copy of anybody they have seen fight and It allows the user to continuously fight and die against the opponents of their choice. It can also serve as an empty space to test out attacks and powers with unlimited magic and energy in the space. Basically like the Hyperbolic Time Chamber but, it only gives combat experience and is used to practice dangerous Attacks and Magics before use. It doesn't make him faster or stronger physically, only more experienced and skillful.
