Special Traits

  • Respect for the Rooster. If the giant basilisk hears the crowing of a rooster it must make a DC 12 Wisdom saving throw, or flee the area. It can make the save again after each of its turns.
  • Keen Smell. The giant basilisk has advantage on Wisdom (Perception) checks that rely on smell.
  • Petrifying Gaze. If a creature starts its turn within 30 feet of the giant basilisk and the two of them can see each other, the giant basilisk can force the creature to make a DC 18 Constitution saving throw if the basilisk isn’t incapacitated. On a failed save, the creature magically begins to turn to stone and is restrained. It must repeat the saving throw as the end of its next turn. On a success, the effect ends. On a failure, the creature is petrified until freed by the greater restoration spell or other magic. 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 giant basilisk until the start of its next turn, when it can avert its eyes again. If it looks at the giant basilisk in the meantime, it must immediately make the save.


  • Multiattack. The giant basilisk makes two bite attacks.
  • Bite. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 22 (3d10 + 6) piercing damage. The target must also make a successful DC 18 Constitution saving throw or take an additional 10 (3d6) poison damage.
  • Poisonous Breath (3/day). The giant basilisk breathes out a poisonous breath in a 60-ft. cone. Any creatures in the area must make a successful DC 18 Constitution saving throw or take 31 (9d6) poison damage.


The giant basilisk is the king of snakes.

It is a massive green and gold monster, and a deadly killer. Some folks say the basilisk was hatched by a rooster from the egg of a toad or a snake. Legend also says this monstrosity can turn someone to stone.

Serpent Leader. Other snakes and snake-like creatures often work in unison with giant basilisks. Although they don’t share a language, they share a common tongue.

Rooster Retreat. Even though these monstrosities strike fear in the hearts of many, they are scared of the call of the common rooster.

Castles and Keeps. On rare occasions, a giant basilisk makes a home in a castle or large settlement.
