Exactly! You get it! But uh, well. I mean there's still the formula. And still machines involved in things like auto-mail and such. But in general depending on what you want to make or fix, yeah, sometimes it can be done with alchemy.

As far as human transmutation, that's. Kind of both impossible and an ethical thing. That you shouldn't use alchemy to try bring someone back to life, or to experiment on humans. It's forbidden to. A rebound is what happens when you try transmute something with too little. It tends to take more in return as a result.

It's an example of what can happen if someone tries human transmutation. My teacher....she lost her baby. Tried to bring them back but because of that her insides, her stomach got messed up. Her insides, her organs and all.

[Izumi didn't talk about it much, but she did open up about it once they reunited after the brothers had tried to bring Trisha back.]
