Skills

Sharp Edge

Weaponcraft: the ability to create and control weapons he summons. He can control the trajetory of the ones he creates at will, and usually after hitting a target they disappear so he can reuse their mass and make new weapons he needs.
For him to create a weapon he needs to know the process of forging it, as well as every material involved in the making of it. The amount of weapons he can create is determined by a limited mass he can bear to generate, which drains his energy. The more energy he has, the larger the limit is. The more complex a weapon is to make, the harder it is to come out accurately.
