So here's my idea: every living thing has magic (better known as souls) in it, with some species having stronger magic than others, or stronger in one type of magic. so the revolutionary part: for creatures who are weaker in magic, there are wands, but to power the wand, you put part of your soul into it, and your magic powers the wand. It's like static electricity, if you poke someone and they get zapped, it might be obnoxious. But if you poke them with a piece of wire, that will be much more effective.
The magic is categorized into three types based on behavior and reactivity. Type one is called 'White Magic' it works on organic material, things like healing, growing, shapeshifting even, etc. It is more effective in wands of wood and bone. Type two is 'Black Magic' the opposite of White Magic, it corrodes and attacks organic material. killing and harming mostly, it is conducted best through metals. The third type is 'Elemental Magic', mostly just Avatar stuff like telepathy. It works best when using stone or metal wands
