"Advance elements are the higher form of the basic element, but lightning and space elements, despite being basic, are still considered advance elements. Anyone knows why?" Elsa asked the class.
Eva raised her hand, making the whole class turn to look at her. "Yes, Eva Williams," Elsa gestured her to stand up.
"Out of all the elements, those two can only be learned by people who are born with the affinity to use them," Eva answered precisely, making Elsa smile and sit back down.
"Exactly, but there is one more issue with the space element. Alyssa, will you explain?" Elsa ordered.
"Using the space element is killing yourself. The amount of strain on the mind the spells put is considerably higher than other elements. That is why there is no mage alive that has reached SS Rank with space element affinity," Alyssa calmly answered, as she knew about the space element the best.
