Cetus is a colossal sea monster with a serpentine body covered in thick, scaly armor. Its dark, mottled skin blends seamlessly with the depths of the ocean, allowing it to remain hidden until it strikes. Its enormous head is adorned with rows of razor-sharp teeth, and its glowing eyes exude an eerie malevolence. The creature’s sheer size and raw power make it a force to be reckoned with.
As it moves through the water, Cetus creates a wake of turbulent currents, and its tail leaves a trail of churning waves in its wake. Its deep rumbling growls and resonating roars can be heard from great distances, striking fear into the hearts of sailors and creatures alike.
Cetus, driven by its insatiable hunger, emerges from the depths to hunt its prey. It uses its massive jaws to snap up unfortunate victims and its powerful tail to smash ships and structures. Its relentless pursuit and devastating attacks have earned it a fearsome reputation, and tales of its encounters have become the stuff of legends among seafarers.
Encountering Cetus is a harrowing experience, as its mere presence can turn calm waters into a maelstrom of chaos and destruction. Those who dare to face this mythical sea monster must steel themselves for a battle against one of the most formidable creatures the ocean has ever known.
Pathfinder Stat Block
This enormous scaled serpent has the head of a shark, powerful claws, and a maw wide enough to swallow a small ship.
Masters of the oceans, the enigmatic cetuses are mighty but slow-witted dragons who demand tribute of any who would dare enter their domain. A cetus’s length and weight are immense, their dizzying coils proving almost impossible to count. Sailors have long told tales of these great creatures, noting that they are almost unstoppable unless they can be turned to stone and left to sink into the ocean depths.
Cetuses prefer to fight their enemies on or under the water, but can leap unexpectedly high to attack foes who dare to take to the air.

The magically infused sea salt in a cetus’s bite tears at some types of magic. Any time a cetus bites a creature under an effect or using a magic item that prevents that creature from being grappled—such as freedom of movement—or that holds the creature aloft— such as fly or air walk—each such effect is affected by a targeted dispel magic. The cetus treats its Hit Dice as its caster level for this effect.
A cetus can uncoil upward, revealing more length than it seems it could possibly possess while soaring to great heights. As a full-round action, it can leap out of the water toward a creature up to 1,200 feet in the air and make a bite attack against that creature before coiling down and returning to its original space. This leap provokes attacks of opportunity.
Being near a cetus is bad luck for nonaquatic 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.
The sea itself protects a cetus. A cetus gains a deflection bonus to AC equal to its Charisma bonus while any part of it is in water.
A cetus takes a –4 penalty on saving throws against petrification, and even on a successful save against petrification takes 1d4 points of Dexterity damage. If its Dexterity damage from petrification ever exceeds its Dexterity, a cetus becomes petrified. Being targeted with a petrification effect suppresses a cetus’s regeneration for 1 minute, even if the creature succeeds at its save.
