[@Zapdos] At the start of the RP? She will have some weak healing magic and cooking skills and knows which part of the knife to avoid (stabby part) but that's it. Him though...well, considering that he's trapped in a body of a girl, he'll be tiny bit faster than someone who didn't train that much, stronger too but at the risk of putting too much strain on the body. Neither of them needs normal food and heal a bit faster than a normal human. 

Towards the end, when they'll actually be strong adventurers? She will have strong healing magic and know how to fight with a weapon (depending on which other character made by other players would want to train her). He will faster, stronger and (not sure yet) either get some blood magic or persuasion skills (control the mind of a person for a few minutes).

The main thing is that while they're a vampire, he can't be in control for too long. She will be in control of the body until they finally learn how to co-exist and share control. As at the start of the RP, she'll be afraid of letting him have control for long periods of time. 

How does that sound?
