Elemental tempering

[OP: ]

As soon as he took out the various energy stones and crystals, the attention of the teachers and the judges was drawn to him. However, the students that were around him were in a confused state right after he was enveloped in that protective barrier.

The teachers knew instantly by their confusion that this barrier was no normal protective wall but instead something much more unique, something that not only was strong but was also something with the illusion properties.

In fact, the headmaster knew instantly that this unique magic engineering artifact was made with the same principles that he himself made his spells with.

Something that was inspired from his spells, and made with the high knowledge that he possessed.

"Hmmm…"

He was smiling, and he was not the only one like that.

"That boy…"

Even their teacher Lady Cleo was surprised when he covered himself with that shield and took out those uncommon stones.
