...Cannibalizing your own kid? I knew we'd get here eventually topic wise, but magic or otherwise,
hard pass. I mean no malice when I say that's a step too far for me, optional or otherwise. For a baddy or a plot thing that's been going on, or something to thwart, or whatever, yeah, super dark, and fits the setting. It could work. For the player?
Sorry, not sorry. For whatever it's worth, that's a nope from me.
As to the curse thing overriding player actions or being a heavy debuff...
I'm honestly confused. There's been a number of times the answer to a thing going on, or effect manifesting is essentially '
no, because I don't want to take away the players agency'. But this is doing pretty much that.
Curse bad, I get it.
Consequences for actions, plot movement, and such, I also get.
But something that alters everything you do, without scratching down on your ledger, with no way to moderate or removes the effects seems... dicey. I'm not saying it's not hot, but... the game seemed to have a decent swath of action and reaction in terms of content. Moreover, I get that the womb tats is supposed to be an affliction, but this is also a power fantasy, and for entertainment. So I guess I'm trying to say keep the players fun factor in mind, if you can.
If the player has opted for it, or there are reasonable ways to deal with it, that's another kettle of fish and all that.

That said, if we're tossing out ideas, largely due to above, here's one from me, using a few of the ideas bandied back and forth, and some themes we've chatted about prior:
Sin Eater / Curse Eater.
By the power vested in banging (or ritual touch, or drinking fluids if it's an ick situation or not a combo the player is all in for) the PC absorbs the curse afflicting another being by drawing it into themselves. The curse is fully (or partially) active, but has a limited shelf life (days, weeks) before it is dissolved entirely, the magic rendered inert and consumed by the protagonist.
This ability makes the user highly resistant or able to devour curses afflicted on themselves much the same way.
However, it does not affect what the body considers it's 'natural' state of afflictions chosen at the start of the game, or rendered by the gods themselves. So a Last of the Line wouldn't change their body back before their loss at the hands of
, Unlucky remains a 'mere' Goblinoid and Futamorph, etc. Or if it does, it's temporary at best before being reset.
Not that such things cannot ultimately be changed or altered, but they'd need more oomph than this ability alone to do so.

Of course, you could always just say fuck it and have a far more simple Paladin style Lay on Hands that straight up nukes curses, but that doesn't seem to be your style at the moment.
