You can't cure yourself when you're a trainee no; you need to be rescued by someone else. It's intended to be that way (fairly overwhelming/guaranteed tf unless you get lucky), but changing it to be more of a process (though also one where the ai puts more effort into slowing you down while you get overcome by obedience and do end up doing the good little maid stuff) is a good idea (with options probably). The way it is currently is roughly the same as visitors are when you catch them unaware in manor mode since it hasn't been refined yet.
For rng stuff, there's an option that changes how rolls are done so your minimum roll is 1/3rd of your combat stat, which alleviates the randomness a lot. Other than that, hmm, combat is meant to be messy but that's more for the manor side, so I might change things up for playing as a visitor mode.
Thanks for the feedback ^^
