Capítulo 286: Praeterea Advance Class

Petronella stood at the front of the class, her gaze sweeping across the assembled students.

"Since you guys are already Praeterea, I'll assume that everyone has learned the basics of amnis. But I feel like I should explain about my own version of amnis," she began.

Petronella started her class with a brief explanation.

"Amnis means river; it indicates which stream is in our body. Which stream will we give to the elemental spirits by giving commands through chants or the amnis we want to cast. So humans can only use amnis when spirit exist. Fortunately, " Petronella continued, " Headmaster Eliphas has full control over the dungeon, so all the spirits are present in this academy."

Petronella gracefully drew a circle of amnis, the ethereal lines shimmering in the air. With a swift motion, she conjured a small fireball that hovered in front of her, only to vanish in an instant.
