Sea Dragon's Shredding Fin

 (海竜の破砕鰭 Umiryū no Hasai Hire) is a Sea Dragon Slayer Magic Spell.

Description
The user swings their hands in an underhand arc towards the opponent, which causes a fissure of water on each side of the user to travel through the ground. On their own the water fissures carry a good deal of cutting power, but upon converging on the desired target, the attack causes a powerful explosion of water to erupt from the point of convergence, damaging the opponent and tossing them upwards with the force of the explosion. If used in the air or underwater, the user instead generates two streams/currents of drilling water that generate the same explosive power upon convergence on the opponent. Heat Magic can cause severe burns on opponents caught in this attack, while Freeze Magic can instead result in said opponents being frozen solid.

With Dragon Force active, using this attack generates two fissures on each side of the opponent, each as tall as the user. Upon all four fissures converging, the result is a massive explosion of a spiraling pillar of water, severely injuring the target and launching the enemy high into the air.
