"Healing" spell but fire
Some of Sea's clones have been spending the last few months in their tower trying to come up with ways they can utilize fire in ways they haven't used before like healing, and other stuff(like domain expansions) that I will make posts about later.
The way this "Healing" spell works is basicaly just transmutation. Let's say one of Sea's arms fell off: he grab's the arm, uses mana to trace it and make a "blueprint" of the arm, turn's the arm into fire via transmutation and uses the "blueprint" to transmute the fire back into the arm.(the short 6 panel comic explains it well I think)(now that I think about it Sea could make things he has made a "blueprint" for out of fire)
While Sea could skip burning the arm part he would have to use more mana to create the arm making it less efficient then just burning the arm.
(if there is anyone that wants to beat his ass they can either blow up his tower or find him eating a random wizard on the street)
