After one week of lessons, all survivors could manipulate the essential elements... to some extent. After that, they decided to focus on training a single element in order to learn an offensive spell as fast as possible. Usually, that would mean that Leon's workload would increase. However, he already explained the theory dozens of times, so the only thing the survivors could do was to practice while he corrects them.
Leon also progressed after training his mana to cover the area around his body; he finally learned the magic that could protect himself from projectiles and all sorts of attacks with a barrier that also let his friends approach him.
Congratulations! You have learned the skill: Mana Shield.
You obtained 01 status points.
