I'll Come Back For You

Grey watched this scene while breathing heavily, although he had been hiding it, blocking so many of the Prince's attacks had taken a large toll on him. He had no issues with his essence reserves, what was troubling him was the impact of each attack after he blocked it. Even with his strong physique, he still had problems with taking such powerful impacts. This showed the large difference between an Elemental Venerable and a Sage Plane Elementalist. 

It was almost unheard of that a Sage Plane Elementalist would be able to exchange blows with an Elemental Venerable, but Grey was doing it with ease. Even though the Prince was only in the First stage, he was one of the people that would be classified as a strong First stage Elemental Venerable. Most people in the same stage would have problems fighting against him.
