Geyser

This spell causes a geyser to erupt from the ground, shooting scalding steam and water high into the air. The geyser shoots up to a height of 20 to 90 feet instantaneously (1d8+1 x 10 feet), and continues to spout for 1 round. The area of effect is a function of the geyser's height; the scalding water falls in a circular pattern around the point of eruption, with a diameter equal to one-half the geyser's height. A creature hit by the geyser itself takes 3d12 points of damage from the scalding water, while creatures within the area of spray take 1d12 points of damage (save vs. breath weapon for half). The geyser itself is 1 to 4 feet in diameter when it erupts.
