Affects the currents of any large body of water. Each application of the spell can shift the current direction by 22.5 degrees or speed by 1 mph (or knot). To achieve combined direction/ speed changes, or more extreme changes in one or the other, increase cost proportionately. 
The spell may be cast on an area, affecting the current moving under it for 40 yards in depth. It can also be cast on an object, such as a ship, which it must then encompass in its entirety. The area of effect then moves with the object.
