Dragonsbreath! First Form!

You take a pose to perfom and call out the whole name of the attack. Then your Shinazugawa sword gets covered on fair red-yellow flames. After that you can move up to your movement speed in any direction you could go (forward, backward, downward, upward, left or right). After reaching an enemy creature you can attack. On hit the red-yellow flames turn into a blue flame building a circle around the target and makes damage. This creature must make a Strength saving throw. A Creature takes your proficiency bonus d10 fire damage or half as much damage in a successful one. +10 to hit.
