The user can change the properties of matter, including density, color, shape, state of matter (solid, liquid, gas, plasma), hardness, ductility, rigidness, etc. They can make things harder/stronger or weaker/more brittle, turn gas into solid, make metal stretch and rubber break as glass. They can make things hotter than the sun, or "so cold that it burns". User can make things as corrosive, to dissolve different matter, combustible, to make things explosive, or inert, which allows them to diffuse bombs by making the material inside no longer explosive even after mixing.
