Water Bomb

This spell enables a wizard to call to hand a grapefruit-sized ball of water, which can be hurled a great distance. At the specified location, the ball explodes into a quantity of water that covers a 15-foot radius circle to a depth of 2 inches.

The wizard can hold the ball of water for no longer than one round before hurling it (after this time, the water runs through his fingers and is lost). The wizard can release the ball upon himself, soaking himself and creating two inches of water in a 15-foot radius around himself. The water is non-magical and is pure and drinkable.

The material component is a small, glass bead.
