Yukine's Signature Spell: Gancelot! [Completed]

Name: Gancelot
Rank: B
Type: Offensive
Description: Yukine abides by the laws of Sekki to instantaneously summon Gancelot. As shown in the image above, Yukine takes on Gancelot's appearance, and when Gancelot is summoned, so is his Pegasus. Gancelot is the superior form of Link; Yukine's strongest C-Rank spell. In order to summon Gancelot, Link must be used first. Gancelot is twice as strong as Link, which, in this case, means he inherits the boosts Link would give to Yukine in any situation, and doubles that amount. For example, if Link once allowed Yukine to travel 1000 feet per second, Gancelot would allow Yukine to travel 2000 feet per second. Additionally, the Pegasus that Gancelot rides on can travel up to 200 meters in altitude. The Pegasus can run as fast as Yukine can. Finally, the Pegasus can instantly cast an immunity barrier around Gancelot, which disallows any nullification magic ranked equal to or less than Gancelot's rank to strike successfully. Please be aware that Gancelot can get off the Pegasus at any point, though if he does, the Pegasus becomes immobile until Gancelot gets back on.

Flight- With this spell, Yukine can travel airborne whilst in battle
