Dorian Pavus / Ranger Stilinski
I'm a Mage, and quite good at what I do. No one can give you guarantees, you know. But death is what I am most familiar with, and healing magic is quite far away from that. It draws off of different energies, and I don't believe there's any risk of making it worse, no.
I would say the biggest risk is that it may not heal as quickly as your son would like.
