Being near a cetus is bad luck for non-aquatic creatures. Any such creature in the cetus's aura must attempt a DC 26 Will save, rolling twice and taking the lower result. On a failed save, that creature must continue to roll twice and take the lower result on all ability checks, attacks rolls, savings throws, and skill checks for as long as it remains within the cetus's aura and for 1 minute thereafter. A creature that succeeds at its saving throw is immune to that cetus's mariner's misfortune for 24 hours. The save DC is Charisma-based.
