Hello hello!
9) Are they a healer or medic?
Myrrha knows some basic healing magic (in the way of necromancy)! So she quite literally has to siphon life force for it. She doesn't mind that part if it's necessary, though, so she's a good backup option if needed. Doesn't know any healing spells/have any medical skills beyond that, though.
Spitz knows basic first aid necessary on the field. Her healing skills are pretty limited, but she can keep soldiers stable if necessary. Better to leave proper healing to the pros!
Buchran only knows the very basics. Like, put pressure on wounds, that sort of stuff. He doesn't like taking on a healing role, but he would out of necessity.
12) Secondary choice weapons?
Myrrha's pretty attached to the greatsword. She started with a staff and wasn't very good at it. If she had to pick an alternate weapon, she'd go with something she can swing around and get results with, so most likely an axe or two!
Spitz is rifle first and foremost, but I think she'd hate having to use a bow. Grenades are a good enough (and satisfying) substitute. If all else fails, a pistol. She's Iron through and through. Machines'll never let you down!
Buchran was a bit of a mix between a deadeye and a bladesworn when I made him cause I couldn't make up my mind, and he's usually a rogue in other settings lol! If he couldn't use the usual sword or gun he'd go with a dagger, instead. Or maybe just his fists, depending. He isn't scared to get dirty in a fight.
21) Roles and builds?
Myrrha's damage damage damage! Tactically speaking, she's very limited. She just wants to smack things hard. Both ingame and in canon characterwise, she uses a lot of chill-based skills so she can also crowd control well enough. She's self-sufficient in the way of consuming life force to heal herself and she usually just fights on her own. This usually doesn't go well for her because she has a habit of biting off more than she can chew (which is also my fault, lol).
Spitz focuses more on aoe and multi-opponent battles. Setting up turrets does wonders, and explosions are fun. She's usually more of a support to the main fighters and she relies on cover being ranged, herself. If anything, she's best at making sure her allies' weapons are in working order. She's support with a gun.
Buchran kinda depends. He prefers being in the thick of it, all about that burst damage. In the past, though, he was usually assigned a ranged role (which he didn't like very much, but it was what he specialsed in at the time). Riaraff would round 'em up and he'd pick them off. He's pretty sturdy, but less sturdy than you'd expect for a tank, so he has to rely pretty heavily on getting the job done quick. He prefers to lone wolf it like Myrrha, too, and he gets really competitive with his allies.
