Ah, crap.
I was going to delve into the necromancer path. Ish.
More specifically a magic researcher who had turned her focus on necromancy.
So she knows necromancy somewhat, a bit of a different but similar magic.
But zero combat experience(researcher, not a full Mage. She learns magic to experience it and assist in her experiments), and zero physical combat skills.
Her probably other skill might be seduction :3
What? We probably need a character to knock out a guard without killing him (^.~)
There's a lot of other paths that would fill that roll really well to be fair. If anything, a magical researcher seems a little less suitable than many other types of character for the mission at hand (breaking into a city and stealing someone.)
Rilla likes characters who had more normal jobs before joining the mission, so a courtesan or a high class escort would fill a similar roll really well.
Or if you'd prefer a slightly less sleazy profession, a con woman, an ambassador or a spy would also fill the same roll really well.
I question how useful necromancy will be considering how far we are from the Undead City.
Still, I'm sure you'll come up with something, and it looks like you have a good idea for team play, a good talker will be useful to our current anti-social party.
