After class, Kayson hummed a little tune as he returned to his office. Back when he was in school, his teachers had often said that reviewing old knowledge led to new understanding. By breaking down and teaching the knowledge of enhancement runes to the young wizards, he had also gained a deeper understanding of it himself.
For example, he could now enhance a damage spell twice to its limit in a spellbook, then draw an enhancement rune in midair to perform a third enhancement.
For instance, a normal person had ten hearts, with two health points per heart, for a total of twenty health points.
A basic damage spell dealt five points of damage. After three enhancements, it dealt exactly twenty points of damage. It was basically a budget version of Avada Kedavra.
"Using this is far more natural and environmentally friendly than Wither Skeletons." As Kayson spoke, he flipped to another page in the spellbook. The Novice Magic Arts Spellbook could not only edit spells, but also edit their sound effects and colors.
So, based on that... hehehehe...
After sneaking into Gryffindor Tower and making a round of reconnaissance without finding Ron's dormitory, Sirius dragged his exhausted body back to the office. He casually drove a boat into the office area.
Then he saw Kayson holding a book, which was crazily pouring miserable green magic into a dummy.
Each blast was accompanied by a thunderous roar.
Sirius's dog face filled with astonishment. The spell Kayson was using looked like Avada, sounded like Avada, and his instincts were now telling him that it was Avada.
Driven by a living creature's innate fear of death, Sirius's mind instantly stopped wandering, and his tongue no longer hung out. He immediately floored the accelerator, spun the wheel, drifted, and vanished with a whoosh.
