Ezra willed all his shadow energy to flow into his shadow tendrils, without stop. The tendrils numbering hundreds and hundreds shot out from the ground all around him into the air.
Seth had already seen this a few seconds before Ezra did it, he was terrified by the vision and now that he saw it in truth he was even more terrified.
"How is it possible that you have so much power?" Seth asked.
Ezra smiled when he heard that question, he looked at Seth and said, "This is not nearly enough of what I need." Then he pointed at Seth, all the tendrils shot at Seth, they blocked out all escape routes, they ensured that they trapped Seth.
Boom, the sound of all the tendrils slamming into the ground and Seth, dust rose and then died down, and we it did, Seth was laying on the ground unconscious.
