Death Fangs (2/Day). The first time the yuan-ti hits with a melee attack on its turn, it can deal an extra 16 (3d10) necrotic damage to the target.

Innate Spellcasting (Yuan-ti Form Only). The yuan-ti’s innate spellcasting ability is Charisma (spell save DC 13). The yuan-ti can innately cast the following spells:

At will: animal friendship (snakes only)

3/day: suggestion

Magic Resistance. The yuan-ti has advantage on saving throws against spells and other magical effects.

Shapechanger. The yuan-ti can use its action to polymorph into a Medium snake or back into its true form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn’t transformed. If it dies, it stays in its current form.

Spellcasting (Yuan-ti Form Only). The yuan-ti is a 6th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 13, +5 to hit with spell attacks). It regains its expended spell slots when it finishes a short or long rest. It knows the following warlock spells:

Cantrips (at will): chill touch, eldritch blast (range 90 m., +3 bonus to each damage roll), mage hand, message, poison spray, prestidigitation

1st—3rd level (2 3rd-level slots): arms of Hadar, darkness, fear, hex, hold person, hunger of Hadar, witch bolt

Variant: Chameleon Skin. The yuan-ti has advantage on Stealth checks made to hide.

Variant: Shed Skin (1/long rest). The yuan-ti can shed its skin as a bonus action to free itself from a grapple, shackles, or other restraints. If the yuan-ti spends 1 minute eating its shed skin, it regains health equal to half its maximum health.


Multiattack (Yuan-ti Form Only). The yuan-ti makes one constrict attack and one scimitar or dagger attack.

Constrict. Melee Weapon Attack: +5 to hit, reach 3 m. Hit: 10 (2d6 + 3) bludgeoning damage, and the target is grappled (escape DC 14) if it is a Large or smaller creature. Until this grapple ends, the target is restrained, and the yuan-ti can’t constrict another target.

Scimitar (Yuan-ti Form Only). Melee Weapon Attack: +5 to hit, reach 1.5 m. Hit: 6 (1d6 + 3) slashing damage.

Dagger (Yuan-ti Form Only). Melee or Ranged Weapon Attack: +5 to hit, reach 1.5 m. or range 4.5/18 m. Hit: 5 (1d4 + 3) piercing damage.

Invoke Nightmare (Recharges after a Short or Long Rest). The yuan-ti taps into the nightmares of a creature it can see within 18 meters of it and creates an illusory, immobile manifestation of the creature’s deepest fears, visible only to that creature. The target must make a DC 13 Will saving throw. On a failed save, the target takes 11 (2d10) psychic damage and is frightened of the manifestation, believing it to be real. The yuan-ti must concentrate to maintain the illusion (as if concentrating on a spell), which lasts for up to 1 minute and can’t be harmed. The target can repeat the saving throw at the end of each of its turns, ending the illusion on a success, or taking 11 (2d10) psychic damage on a failure.
