Depend what you mean by healing and restorative
Sometimes healing imply both terms in games, and maybe in Solo leveling it does, or she have "Restorative magic" instead of "Healing"... dunno
Healing magic would only be able to heal, so the B rank adventurer lost his arm forever
But restorative term is more profound, since it... restore ?
So it could restore limbs / flesh / bones like a fresh new one since it already existed before
In the end, I have only one thing to say : MAGIC ! ^^
