Sea Dragon's Geyser

 (海竜の間欠泉 Umiryū no Kanketsusen) is a Sea Dragon Slayer Magic Spell.

Description
The user covers their hand in water, then presses their palm against the ground. Their magical energy then flows underground until it reaches the location of the opponent, after which it erupts into a powerful geyser from underneath the enemy. While not actually very damaging, the geyser can easily surprise enemies and launch them into the air, leaving them vulnerable to attack or disrupting enemy attacks. This Spell is especially effective due to the fact that the time between the user touching the ground and the geyser's eruption is nearly instantaneous. The user is capable of controlling where and when the geyser will release, which can make for very effective time-delayed traps. By rapidly pressing their hands against the ground, the user can generate several geysers in succession, which erupt in time with their hand presses. By pressing both of their hands against the ground at the same time, the user can generate a single much more powerful geyser.

With Dragon Force in effect, the user is capable of creating enormous geysers with ease, large and strong enough to through entire groups of enemies high into the air.
