Actions

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 5 (2d6 + 4) piercing damage. If the target is a creature, it must succeed on a DC 16 Constitution saving throw or suffer one random poison effect:

Constrict. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 9 (2d8 + 1) bludgeoning damage, and the target is grappled (escape DC 12). Until this grapple ends, the creature is restrained, and the snake can't constrict another target.

Hypnotic Gaze:. Choose one creature the cobra can see within 5 feet. If the target can see the cobra, it must succeed on a Wisdom saving throw (DC16) or be charmed by the cobra until the end of the cobra's next turn. The charmed creature's speed drops to 0, and the creature is incapacitated and visibly dazed. On subsequent turns, the cobra can use it's action to maintain this effect, extending its duration until the end of it's next turn. However, the effect ends if the cobra moves more than 5 feet away from the creature, if the creature can neither see nor hear the cobra, or if the creature takes damage. Once the effect ends, or if the creature succeeds on its initial saving throw against this effect, you can't use this feature on that creature again until you finish a long rest.
