Stoichokinesis is the power to actually fuse and create new chemicals by merging different elements (Of the periodic table) together with the mind. This is extremely hard as it is breaking down liquids into simple elements such as carbon and nitrogen. Then fusing them together to form a liquid such as blood or glucose. Stoichokinesis can be developed to such an extent that it can be considered able to make 'potions' or 'remedies' just with your knowledge of fusing elements. One may even take apart a complex liquid to make the simple element of gold (Although still a superstition).
