Everyone looked at Ellena with shock. Apparently, they just witnessed an attack with two elements of magic. It is not uncommon to see since basic magic lets you have a small grasp of the basic elements, which are fire, water, earth, and air.
However, what they witnessed was an offensive magic attack, which can be used only if you have an ability pertaining to that element.
As there were also mages who were watching the fight, they couldn't help but admire Ellena. She had a high-ranking rune on their points of view.
In the magic society, there are people who weigh your ability. If you can use one element with only one ability, you are considered average. However, if you can use more than one, and also have two separate abilities for those elements, you are considered a genius.
