Special Traits

  • Dive Attack. If the sphinx is flying and dives at least 30 ft. straight toward a target and then hits it with a melee weapon attack, that target must succeed on a DC 15 Strength saving throw or be knocked prone. If the target is prone, the sphinx can make one bite attack against it as a bonus action.
  • Flyby. The sphinx doesn’t provoke opportunity attacks when it flies out of an enemy’s reach.
  • Inscrutable. The sphinx is immune to any effect that would sense its emotions or read its thoughts, as well as any divination spell that it refuses. Wisdom (Insight) checks made to ascertain the sphinx’s intentions or sincerity have disadvantage.
  • Keen Smell. The sphinx has advantage on Wisdom (Perception) checks that rely on smell.


  • Multiattack. The sphinx makes three attacks, one with its bite, one with its claws, and one to constrict. It can replace its bite attack with a use of Weird Insight.
  • Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) piercing damage.
  • Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage.
  • Constrict. Melee Weapon Attack: +10 to hit, reach 5 ft., one creature. Hit: 8 (1d8 + 4) bludgeoning damage, and the target is grappled (escape DC 15). Until this grapple ends, the creature is restrained, and the snake can’t constrict another target.
  • Weird Insight. The sphinx targets one creature it can see within 30 feet of it. The target must contest its Charisma (Deception) check against the sphinx‘s Wisdom (Insight) check. If the sphinx wins, it magically learns one fact or secret about the target. The target automatically wins if it is immune to being charmed.


Before you reclines a strange-looking amalgamation of lion, bird, reptile, and woman. From a lion’s body sprouts wings and a reptilian tail, which is topped by the bosom and head of a woman. The face is impassive, almost sad, in demeanor.

Born of Echidna and Typhon, sphinxes have the attributes of a female woman, a lion, and a serpent’s tail.

Sphinxes are fond of asking riddles and devouring those who answer incorrectly. They are rare, however, because if a particular clever traveler answers the riddle, the sphinx is likely to kill herself.

The Punisher of Thebes. The most famous sphinx was sent by the gods to plague the town of Thebes as punishment an ancient crime, eating all who failed to solve her riddle. King Kreon of Thebes offered the throne to the one who could stop her. Oedipus solved the sphinx’s riddle, whereupon she cast herself off the mountainside in despair.

In close combat, sphinxes use their powerful claws to flay the flesh from their enemies. Despite their deadly nature, they prefer to avoid combat whenever possible.
