IN the case of a water elemental, dousing a steam golem destroys the elemental and the golem must make a DC 20 Constitution saving throw. If it succeeds, the water instantly evaporates and the golem continues functioning normally. If it fails, the golem's fire is extinguished and the boiler loses pressure.
