Makes me wonder if Listen to Wind would have a Summer Mantle. He being a healer, and being big on protecting nature seems like a natural fit for him.
It seems to fit, but from the descriptions we have, I wouldn't be sure. For one, he apparently has to keep going to medical school to keep up, which is consistent with regular wizardry "healing," which requires that you know what you're doing, as opposed to Summer Magic healing, in which the sponsor does all the hard work.
Also Elaine did some magical healing stuff, using Reiki to move energy around or somesuch, in White Night.
Yeah, that's the clearest basis for an example in the DFRPG books -- with the caveat that it only works on certain types of injuries (mainly blunt trauma -- it won't make wounds close any faster, and even then, only up to a certain severity).
The sense I've gotten is that magical healing basically does what mundane medicine can, only different and
sometimes slightly faster.
