Swavain basilisk

The Swavain Basilisk is a type of sea serpent commonly found in the Swavain Islands and elsewhere in Wildemount. Rather than petrifying creatures with its gaze, Swavain basilisks excrete an oil which is capable of turning creatures to stone. Swavain basilisks often hunt and nest near shipwrecks.

Appearance
Swavain basilisks are long, thin sea serpents, which commonly grow to lengths of 25 feet from snout to tail. They are fast-moving in the water, and prefer to ensnare prey in a constricting grapple before paralyzing them with their oily excretion.

Abilities

 * Multiattack: The basilisk makes two attacks, one with its bite, and one with its tail.

Trivia

 * In, Pumat Sol asked the Mighty Nein to obtain for him a vial of Swavain basilisk oil. The party has yet to complete this quest.
