Boom... Crack, crack... As the arrow came into contact with my ice wall, it pierced through like a hot knife through butter, continuing its path toward me.
Unison Attack:an extremely powerful technique used by the elves, where two to five of them combined their mana into a single potent unit, multiplying the power several times. Being a high-level skill, it was difficult to master—only a few hundred had managed to do so, even after centuries since its invention.
This technique was their trump card, used against overwhelmingly strong enemies during the war to protect the kingdom's borders. It was invented centuries ago by an elven genius during the Devil's Raid. Relying on Elara's ability to see the future, they would locate the strongest enemy and use the Unison Attack to annihilate them.
