This Drakonit had succeeded in sending particles of darkness into his organism, probably when he had managed to wound him in the shoulder. They were the only ones capable of creating this kind of internal damage, and only a very powerful mage could remove them from his body now.
As he ran toward that Drakonit again to try to stop him from casting this spell, he was pushed back and thrown against the protective barrier by a wall of red and purple fire with black spots on it that had formed all around him. Then this wall of fire rose sharply into the sky, destroying the protective barrier of the arena.
When Vacily saw this extremely threatening wall of fire advancing toward him, he immediately took a black pill, which also took him to a whole new level.
