Gil released the arrow after giving it some of his mana. Unlike the other arrows, when Gil added his mana to it there was a sudden pulling of light element around them. It wasn't powerful but it was a much different sensation. Everyone could tell that the arrow was much different than any they had used before.
As the arrow traveled through the air it was clear that it was gaining more and more of the light elemental mana. The shape and color were changing in to that of a bright white arrow of double the size. The light was manifesting all around the arrow as a physical attack.
Before anyone could speak on this amazing phenomenon the arrow hit the dummy dead center. The surprising part was that it did not stop. It pierced through the dummy and embedded itself in the wall. The light elemental mana slowly faded from the arrow after it was stopped and the entire room held a deep silence.
