While we are on the topic of Transmuters. As they are masters of transmuting living matter how about a spell that allows them to mend themselves. It would be a high level spell that allows them to mend their own broken bones and bleeding wounds. Perhaps even heal themselves some. The downside of this would be it could only be done once every twenty four hours and it's lag would be huge. It would be very usefuly but nowhere near as useful as a healer.

That which does not kill us,
makes us stronger.
