Special Traits

  • Detect Good. The Abyssal basilisk can detect fey and celestial creatures within 60 feet as an ongoing effect.
  • Foul Breath. The Abyssal basilisk’s breath is so putrid it creates an area of foul gas in a 5-foot radius around itself. Any creature entering that area or starting its turn within that area must succeed on a DC 13 Constitution save or become poisoned until the start of its next turn.
  • Magic Resistance. The Abyssal basilisk has advantage on saving throws against spells and other magical effects.


  • Multiattack. The Abyssal basilisk makes one Bite attack and two Claw attacks.
  • Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 17 (3d8 + 4) piercing damage plus 10 (3d6) poison damage.
  • Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage.
  • Petrifying Gaze. If a creature starts its turn within 30 feet of the Abyssal basilisk and the two of them can see each other, the basilisk can force the creature to make a DC 15 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 at 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 Abyssal basilisk until the start of its next turn, when it can avert its eyes again. If it looks at the Abyssal basilisk in the meantime, it must immediately make the save. If the Abyssal basilisk sees its own reflection within 30 feet of it in bright light, it must succeed on a DC 10 Wisdom save or mistake itself for a rival and target itself with its gaze. The Abyssal basilisk’s magic resistance gives it advantage on any resultant Constitution save versus its own gaze.
