OoC: @Slenn Keep in mind, the idea here is to have magic that can be explained by science, or at least soft science. Anyway, the idea is that healing magic in this verse works by coating the wound in a substance that can replicate bone, muscle, skin, etc, then pumping energy into it and the surroudning area to promote healing. However, it requires special training, a bit of time, and for the subject to have enough protein, calcium, whatever, to remake the damaged area.
