Finally a Clue

The day had been fruitful to Arthur and Philip. Both learned tier 1 spells. Philip with his Thorns spell, and Arthur with some basic fire spells such as Fireball, Ember, Blazing, etc.

They were back in their dorm, tired of all the practice. Arthur was not done for the night. He left the dorm, looking for a remote place to test his theory.

It was all dark, yet he could see it perfectly.

"If this works, I'll become the greatest mage there is." Arthur thought.

The theory he had in mind was to use the sunlight energy he absorbed for his Dragon Fire Body, and try to enhance his other fire spells.

He moved his hand, channeling one of his newly gained spells, Fireball. It was only but a tier 1 spell, but the moment Arthur tried to use his sunlight energy, more circles appeared.

One, two, three… six circles. The simple tier 1 Fireball increased 5 tiers when using that energy.
