Once every 1d4 rounds as a standard action, Dagon can exhale a 60-foot cone of inky blackness. Underwater, this cone manifests as black ink, while above water it manifests as a thick cloud. Creatures in the area have their vision obscured as if they were in complete darkness. Darkvision does not allow someone to see through the ink or smoke, but true seeing does. The ink or smoke persists for 1d4 rounds, but dissipates in 1 round in areas with aquatic currents or winds. Any creature in the breath weapon's area is exposed to the breath weapon's poison (see below) and must succeed at a DC 41 Will save or gain 2 negative levels as its memories and knowledge leach away (this is a mind-affecting effect). Any creature that enters the ink or cloud, or ends its turn inside it, must succeed at another Will save (at a +4 bonus) to avoid further level loss and poisoning. The save DC is Constitution-based.
