"Its done," Damien finished the treatment. He stopped using the spell and looked at Wistoria's arm. Though her arm had not completely recovered, it no longer looked as scary as before. The scars had lightened, and as long as she paid attention to the treatment, Damien knew that her arm would get better.
He told her, "From now on, try to rest your right arm as much as possible and make sure to receive treatment from me three times a day. As long as you follow my orders, your arm will get better in three days."
This was an amplified version of burn ointment, and coupled with Wistoria's healing rate, three days should be more than enough.
"Are you sure?" Wistoria asked. "The healers can treat burn wounds in seconds. So why are you taking three days to heal me?"
She was curious to know what the difference was between Damien and the healers.
