Basilisk

Basilisks are reptile-like creatures known for their ability to turn other creatures to stone.

On Exandria, there are several varieties of basilisk. Some basilisks are kept by duergar in the Underdark. Ice-scaled basilisks can be found in the Frostweald. Those land-based, lizard-like basilisks are physically distinct from their much larger, serpentine, aquatic cousins, the Swavain basilisks.

Creature Information
Land-based basilisks are medium-size, eight-legged, lizard-like creatures that are considered very dangerous due to their natural abilities. The duergar in Emberhold raised these creatures as guardians and weapons.

Swavain basilisks are huge, sea-snake-like creatures. They are drawn to shipwrecks, where they can hunt treasure-seekers, but they also are known to hunt ashore and along inland waterways.

Abilities
Land-based basilisks are known for their petrifying eyes that can turn others into stone should both creatures make eye contact. They also are capable of poisoning their opponents.
 * Petrifying Gaze
 * Poison

Swavain basilisks also have a poisonous bite, but they petrify their prey with their thick, oily secretions.

Pre-Stream
Vox Machina had a basilisk encounter in the Frostweald in which Vex was briefly petrified.

In Thunsheer 836 PD, Pumat Sol offered the Mighty Nein 5,700 gold if they could procure a vial of Swavain basilisk oil in the next couple of months.
