Traits

Legendary Resistance (3/Day). If the basilisk fails a saving throw, it can choose to succeed instead.

Amphibious. The basilisk can breathe air and water.

Deathly Gaze. If a creature starts its turn within 30 feet of the basilisk and the two of them can see each other, the basilisk can force the creature to make a DC 14 Constitution saving throw if the basilisk isn't incapacitated. On a failed save, the creature's health is reduced to zero and it falls unconscious. 

A creature that isn't surprised can avert its eyes to avoid the saving throw at the start of its turn. If it does so, it can't see the basilisk until the start of its next turn, when it can avert its eyes again.

If it looks at the basilisk in the meantime, it must immediately make the save. If the basilisk sees its reflection within 30 feet, the basilisk's gaze is reversed on the basilisk.

Description

The Basilisk was a giant serpent, also known as the King of Serpents.

Looking a Basilisk directly in the eye caused instant death, but an indirect look would merely render the victim Petrified.

It was also the mortal enemy of spiders. Spiders refused to speak of the Basilisk, could intuitively sense their presence, and would flee whenever they sensed them.

The Basilisk was a snake-like creature that has been documented to grow up to fifty feet in length by Adulthood. Their scales were a dark green colour with a lighter green underbelly. A male Basilisk could be distinguished from a female by a single scarlet plume on its head, which females didn't have.

The Basilisk had horns on its head. They also possessed rows of incredibly sharp venomous fangs and large yellow eyes.

Lair and Lair Actions

 

Lair Actions

On initiative count 20 (losing initiative ties), the basilisk takes a lair action to cause one of the following effects; the basilisk can’t use the same effect two rounds in a row:

  • A wave of water washes up in an area the basilisk can see within 120 feet of it surge outward in a grasping tide. Any creature ion the ground n a 30 ft by 40 ft rectangle must succeed on a DC 15 Strength saving throw or be pulled up to 20 feet away from the basilisk and knocked prone.
  • A deadly gas rises from the ground at the point of up to 2 creatures on the ground the basilisk can see within 120 ft. Each creature in the gas must make a DC 15 constitution saving throw or take 18 (4d6) poison damage, and be poisoned until next lair initiative count.
  • The basilisk summons one swarm of snakes within 60 ft. The snakes take their turn after the basilisk, and the basilisk can telepathically control them. The snakes last until they die. 

Regional Effects

The region containing a basilisk’s lair is warped by the dragon’s magic, which creates one or more of the following effects:

 

The land within 6 miles of the lair takes twice as long as normal to traverse, since the plants grow thick and twisted, and the swamps are thick with reeking mud.

Creatures can sometimes hear whispering in nearby walls. 

Snakes seem to gather and work together withing 6 miles of the lair.

If the basilisk dies, vegetation remains as it has grown, but other effects fade over 2d6+2 days.
