Traits
Devil's Sight. Magical darkness doesn't impede the yuan-ti's darkvision.
Magic Resistance. The yuan-ti has advantage on saving throws against spells and other magical effects.
Actions
Multiattack. The yuan-ti makes three Bite attacks or two Spectral Fangs attacks.
Bite. 6 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage plus 7 (2d6) poison damage.
Spectral Fangs. 6 to hit, range 120 ft., one target. Hit: 16 (3d8 + 3) poison damage.
Merrshaulk's Slumber (1/Day). The yuan-ti targets up to five creatures that it can see within 60 feet of it. Each target must succeed on a 13 Constitution saving throw or fall into a magical sleep and be unconscious for 10 minutes. A sleeping target awakens if it takes damage or if someone uses an action to shake or slap it awake. This magical sleep has no effect on a creature immune to being charmed.
Bonus Actions
Change Shape. The yuan-ti transforms 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. It doesn't change form if it dies.
