@Eliakub19 They have a "semi-awareness", that is, they are still connected to you and are exactly like you, although they can act by their own. Think of this like stands from JoJo, where despite practically sharing the same soul and mind, they have their own counciousness by themselves. And yeah, you could keep the knowledge of your clones, and you could send your "true-self" through the clones body, thus making you semi-immortal.
Just alchemy that can be used personally.
