Thank you, both of you! To be honest, the two Vulfman scripts look more complicated than I actually need, so I think I'll use KK20's script, but those scripts could be really useful in the future.
EDIT: Actually, I have a question. KK20, in your example config, the bonus value for Heal is positive. Would that make the skill heal more HP with each level, or would it actually make it heal less (and eventually maybe do damage)?
