As an action, you create a whip of water that pulls and unbalances a creature that you can touch or see within 10 meters. The creature must make a Reflex saving throw.
On a failure, it takes 3d8 bludgeoning damage, is knocked prone if it is Medium or smaller, and is pulled 2 meters toward you if it is Medium or smaller.
On a critical failure, it takes twice as much damage and is pulled 4 meters toward you if it is Medium or smaller.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
You can increase the damage by 4d8 and affect a creature of a larger size for each additional mana expended.
