Seth is hit by his Lightning, but his flesh absorbs it as if a breeze. "Foolish!" No sooner had seth mocked him had the Glacier been summoned against his flesh. The cold chills his hot blood, and the combination of forces is jarring to even one such as Seth. It was as if he was chosen to play the Titanic in this reenactment.

The colossus seems stunned crashing into the ground tearing through anything that would prevent him from crashing into the surface of the earth. Though jarred the Dragon is far from done, if anything it would seem the startling realization that they made him feel pain acts a spur to enrage him further.
