You slip a healing potion into someone's soup and suddenly their body is rejecting most of their organs.

You've invented one of the most insidious poisons ever. There's not even a decent cure for it unless said victim is already stocked on potions themselves (which they likely wouldn't because something this fucking complicated would be worth a fortune).

If you take them enough, you might find your body state being thrown further and further into the past, and possibly to a point where you were even worse off.
It doesn't add to your lifespan, it actually eats it because your body has been brought to this point twice: once normally, and once by the potion.
You could level down by accident.

What happens if you calibrate one to an animal and drink it? Do you retain your sapience? What about the other way around; do you get a suddenly intelligent animal brain in a human body, or a retarded human?

There is no god damned way that such a potion would be affordable in a setting where non-divine healing wasn't already easy

Also, this.
If Time Stop is a goddamned 9th level spell, what do you think reversing time, even on a single subject, would take?

The storage of the scan is not perfect. There is a 0.01% degradation that excarbates with multiple scans. At noticible degradation, may result in tumorous growth, neurological damage, and/or death. In extreme cases, may turn the subject into a meat slime.

>reloading a past state

If i reload a past state that was at a lower elevation than the one i am currently at, where does the energy go?

It doesn't reverse time at all, just overwrites differences in shape. Since you're being polymorphed into yourself, it doesn't take much magic to do.
In fact it's less magic than it would take to polymorph someone else into you, so if the potion is intentionally used by the wrong person it won't be a perfect disguise.

Literally how blood vials in Bloodborne work. You're not directly healing yourself, you're using the blood in the vial to revert back to a time you didn't feel like shit.

It gets addictive. Fear the old blood.

What are potions made from?

>It works by being calibrated upon purchase to store a scan of the user's body at perfect health.
Right, a full body scan of a person's body stored within a liquid. Super easy!

>When it's activated, it applies low-level transmutation magic to any differences in the user's body, effectively reloading a past state, but doesn't affect the mind because souls exist.
I'm not sure you know what low level means. Even if it's being applied judiciously, that kind of technique ought to apply just as easily to healing magic.

>Since you're being polymorphed into yourself, it doesn't take much magic to do.
If that was true, other forms of healing magic wouldn't exist at all.

It also can't be a polymorph effect because those are temporary and still more expensive than most healing spells.

>In fact it's less magic than it would take to polymorph someone else into you, so if the potion is intentionally used by the wrong person it won't be a perfect disguise.
That's actually kind of an interesting place to go with it, though.

Wouldn't bacteria and virus come back to their original state?

This would also imply the immune system is dialled back to before dealing with any disease or virus, leading to be vulnerable to certain infections, or probably strengthening the bacteria affected by the potion, leading to super diseases.

Since gaining skills is often about muscle memory as much as anything, you might lose experience as you rewind your body to a previous state. You'd remember all that training but your body won't. You'd also lose any physical stat increases you had since you were scanned.

Therefore, every time you gain a level or improve a stat, you'd want to get all new potions. Congratulations, you've introduced save scumming into your game.

I would make it work, but it would be pretty expensive. Essentially what you're doing here is creating a minor simulacrum, suspending it, and the swapping it out, so that's a pretty high level spell effect.

I'd make it so that the potion has to be calibrated to the user when made, not purchased, so that each one is a custom made-to-order affair. The potion would require you to put half all of your hit dice (if 5e) into it as a blood sacrifice. When drank later, it would allow you to roll all of those hit dice at once. The potion is at full strength for one day, but after that it loses half of its remaining hit dice per day, because it's difficult to keep something as complicated as an entire living body in a single small potion. The shock of suddenly having your body "reverted" also gives one level of exhaustion.

>half or all your hit dice
I meant to say

Anyone who drinks it is perfectly healed, but any memories they created after calibration are gone.

>but doesn't affect the mind because souls exist
Or it could affect it. Each use damages your soul a bit. It causes memory loss and mental fatigue(temporary negative levels or something). Using one will keep you in the fight, and you can rest later, but using too many will make you forget who you are or kill you outright.

>revert to peak health
A good way to reverse aging; healing itself is just nice side-effect. Since in DnD death due old age is oh so natural...

>It doesn't reverse time at all, just overwrites differences in shape.
