Duration: 	Permanent
Saving Throw 	None
The user spits out a great volume of water from their mouth, swallowing up and crushing the enemy with the advancing surge. The user can ride the wave, allowing them to move at high speed, and attack the enemy, now swept off their feet, without fear of counter-attacks.
The user performs a bull-rush attempt against all enemies within range of the technique and can travel up to 4x their normal land speed during this attack. You can only move in a straight line, and you can make a single melee attack against each enemy your movement takes you past at your highest bonus. The bonus on your bull-rush attempt is equal to your caster level. Every 10 caster level the user gains a +4 bonus to this bull-rush attempt and this bull-rush attempt does not provoke attacks against you. Enemies caught in the burst take 1d4 points of damage per 5 ft. that they are pushed back by the wave of water.
After the jutsu is resolved, the terrain is considered an aquatic environment, with a depth equal to the user's caster level.
