Sea Dragon's Roar

 (海竜の咆哮 Umiryū no Hōkō) is a Sea Dragon Slayer Magic Spell.

Description
The Sea Dragon variant of the Dragon's Roar technique commonly seen among Dragon Slayers. The user inhales deeply, before firing a pressurized stream of water at the opponent, with carries a great amount of force behind it, enough to push back multiple enemies caught in the attack. Unlike typical manners of firing a Dragon's Roar, the user does not fire it with their mouth gaping wide like an actual roar, but pursed like blowing into an instrument. The Sea Dragon's Roar can be sustained for a certain amount of time, but only up until the user runs out of breath. As with other Sea Dragon Slayer Spells, the temperature of the water can be altered at the will of the user, from scalding hot to freezing cold. Combining this feature with either Heat Magic or Freeze Magic allows the temperature range to increase even further, from hot enough to actually burn a user of Fire Dragon Slayer Magic, to cold enough to freeze someone caught in the attack for too long.

When used with Dragon Force activated, the form and power of the attack take on a massive change. The attack is not only fired like a typical Dragon's Roar attack (mouth gaping wide), but also produces a powerful cyclone of water that carries immense destructive power even without the temperature altering abilities of Sea Dragon Slayer magic.
