The prince definitely wasn't expecting to see someone with a darkness attribute so as soon as he perceived the arrival of three arrows from different directions that were going to destroy his shield even while being weak (tier-1) personal spells, he used the winds that were still under his feet, took a half turn, and faced the arrows head on.
They were darkness attribute arrows, so technically, they should only be powerful against weaker light attribute spells. He thought he could easily face them with his Aura-covered sword, but he was wrong this time.
His Aura was indigo, a very bright shade from his light indigo hair. It was a unique Aura with the properties of light and it was also just like a ray of light swirling around his blue blade.
As soon as the three arrows passed through his shield and he tried cutting through the three spell arrows, to his surprise, he felt as great of pressure as facing a solid sword.
