re: captchaloguing living people, I sent in an ask the other day about this but I guess it got lost in the void. Anyway, if that's possible, then you can probably also alchemize living people. To avoid philosophical weirdnesses though you'd probably want to just instruct your sprite to clone you if you die, not actually make duplicates of anyone who's still around.

Also, if you can captchalogue a person, you can then double-punch that card with a ghost image of their fursona. No self-prototyping and god-tiering necessary, just alchemize yourself into a furry instead.

There’s a possibility that while the Alchemiter could biologically reproduce your structure, it couldn’t exactly reproduce your Soul, so you may just end up with a Captcha Card that can make corpses of yourself. Not too pleasant. Unless you have a Heart Player to drag your Soul into the intact, newly created body maybe? There’s a lot of weird things you could do going down this rabbit hole.

And speaking of rabbit holes you can go down with, I’m preeeetty sure the Fandom is already quite acquainted with Alchemiter Character Fusions.
