"What is it? Fusion magic?" Leria asked.
"That too, but it's not what I was talking about." Lith shook his head. "You both have developed your own breathing technique in order to self-Awaken but you have no idea how to use it and how it works. Sit down with me."
Lith then proceeded explaining to them the difference between Accumulation and Invigoration. The children had already found their breathing rhythm and even though they had never used it after their breakthrough, it was deeply ingrained in their bodies.
"Always remember the risks." Lith said while they practiced the harmless Invigoration. "The more you use Invigoration on yourself or others, the less effective it becomes.
"Even if you use a nutrients potion, the strain on your body caused by the instant regeneration piles up. The same happens to your mana core. Invigoration refills it but the mana abuse makes each spell more taxing and reduces its efficiency.
