Water Magic

Turbulent Sphere

3-level Evocation

Choose a point in range that you can see, water rushes out from you and forms into a 15 foot radius sphere of moving water. Any creature caught in the area can not breathe, and at the start of their turn must make a Constitution save or take 3d6 points of bludgeoning damage on a failed save.   Any lightning spell that touches the sphere, considers the area of affect of the spell increased by 30 feet as long as the target is within the sphere.   While within the sphere, you can cast the spell Waterblade without concentration, but dissipates as soon as you leave the sphere.

At higher levels: When cast at 4th level or higher, the radius and range of the spell increases by an additional 10 feet for each level cast above 3rd.
