Water Jet (Su)

A thalassic behemoth can blast water from its blowhole with surprising force and accuracy. This water jet has a range of 240 feet with no range penalties. A target hit by the water jet is subject to the behemoth's push ability and must succeed at a DC 32 Fortitude save or be stunned for 1d4+1 rounds. The save DC is Constitution-based.
