After thinking about healing magic for a long time, I tweaked some of the abilities of The Way and added some anecdotes about the process of regenerating limbs or other body parts. The net effect is that, while it is possible, it is on the scale of (21st Century comparison) putting a satalite into orbit. That is to say, Bob, down the livery stable would not have the capacity to do that.
This change came as the result of working through Norad's character arc and planning the character arc for a future (as of this writing) character, Hanlee, who will appear in a collection called Against The Brotherhood.
