Swavain Basilisk

Pearl divers and seafloor scavengers sometimes tell tales of mysterious ocean gardens filled with statues of sea creatures and sailors—the underwater grottoes of the deadly Swavain basilisk. Though named for the Swavain Islands where they are most commonly found, these dangerous hunters have been known to wander inland waterways, and have even been spotted in subterranean sewer systems.

Death’s Slimy Embrace

Physically dissimilar to its land-based cousins, the Swavain basilisk is a thin, elongated sea serpent that commonly grows to lengths of twenty-five feet. Its sinuous body lets it move rapidly through the water and ensnare prey with equal ease. Unlike the deadly gaze of its land-based cousin, the Swavain basilisk secretes a thick oil that can turn other creatures to stone. Petrified prey sinks to the ocean floor, where the basilisk feeds at its leisure, the devoured bits returning to flesh once consumed. If processed properly under the supervision of an experienced alchemist, the basilisk’s oil can be used to reverse the petrification effects it causes.

Shipwreck Steward

Swavain basilisks occasionally hunt ashore under cover of night, but are more often drawn to hunt and nest near the sites of shipwrecks. When salvage parties and treasure hunters seek out those wrecks for profit, the Swavain basilisk adds more drowned stone to its collection.

Amphibious. The basilisk can breathe air and water.
Petrifying Secretions. A creature must make a DC 13 Constitution saving throw if it hits the basilisk with a weapon attack while within 5 feet of it or if it starts its turn grappled by the basilisk. Unless the save succeeds, the creature magically begins to turn to stone and is restrained, and it must repeat the saving throw at the end of its next turn. On a successful save, the effect ends. On a failure, the creature is petrified.
