uhhhmmm. i have a good amount of physician ocs i think there's a lot of them who are at worst decent at medical care. but for specifics i'll just list down the ones i think i talk about the most

Salome: she is a physician. she was studying to be a surgeon but she quit halfway through for Reasons. but she knows what she's doing and she can perform surgery in a pinch but do NOT expect any sort of uh.. emotional nursing or something. actually being taken care of beyond the injury. She'll tell you what to do and when to do it but idk if she'll stay beyond what she deems necessary. she's got places to be

Markus: dependable enough. much better at trying to nurse them back to health instead of the patching though. good if you like soup and some really nice food because he has an entire garden of herbs to make use of

Felix: he fixes up scratches and normal bruises and maybe some kind of deep wounds but i don't think he can do much beyond that. he's good at taking care of people in general though so I think you'll be fine but if it's anything more serious he'll probably just take them to a hospital

Lysander: i don't think he'd even register he's bleeding out until he's lightheaded so he'll probably pass out before he could try to patch himself up. 0 self preservation whatsoever. i think he'd be able to bandage people alright though... i just don't think he'll call for help even if he probably needs it
