Continuous Use Of The Fusion State

Bill moved closer to Grey, wanting to attack once again. However, this time, Grey didn't try to engage in hand t o hand combat with him, rather, he retreated and used his fire element to unleash an attack. Pm

Bill was forced to receive the attack since he never expected Grey to suddenly switch to elemental attacks. Blocking the attack, he was pushed back by the impact of the attack. 

Grey used his fire and lightning domain simultaneously, while inscriptions lit up in the sky. He was done with playing, although he enjoyed the hand to hand combat, he couldn't keep up with it for too long. 

When Bill noticed that Grey had switched to using elemental attacks, he felt a little downcast as he switched as well. He would've preferred fighting with their physical strength, but since Grey wanted to switch, then he would as well.
