This technique creates a large ball of water that bursts forth, spiraling in a way not unlike the much more potent Daibakufu no Jutsu would. Any creature caught in the line of effect suffers 10 points of water damage which can be halved with a successful Dex save. Any creature damaged by the attack must also make a Str save to avoid being knocked back 5 feet. If knocked back into another creature, both the target and the creature it is knocked into must make a Dexterity check (DC 10) to avoid falling prone. The line cannot be longer than 30 feet.

Material Focus: A small (at least 15 litres) source of water nearby.
