This spell causes a cloud of super-heated steam to rise from the surface of the water, dealing an initial 1d6 points of damage to anything within its area of effect. The second round, the steam inflicts 2d6 points of damage, and an additional 1d6 each additional round, after which the gout of steam dissipates immediately. This spell is usually used to attack ships, as it has a chance to cause damage to every sailor onboard.
