"It seems that you guys have rested enough, so it is time to teach you the next technique," Rain said, trying to look like he didn't forget his promise. "You all have practiced Meditation enough to know a bit of how to control your mana, so I am going to teach you how to heal yourselves in the middle of a battle. One of my wives can heal you when you suffer severe wounds, but she is only one person. Your main job is to keep yourselves in tip-top shape."
Rain's goal was to make his soldiers as tough as possible by making them focus on endurance and on healing themselves… that would make them an army that can keep fighting even if their bones are broken, and their flash is cut… it would be nice if they could keep going even if they suffer harsher wounds, but that was a goal for the future.
