The snake's attacks are magical.
The snake regains 15 hit points at the start of his turn if he has at least 1 hit point.
Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 5) piercing damage plus 10 (3d6) radiant damage.
Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 23 (4d8 + 5) bludgeoning damage, and the target is grappled (escape DC 19). Until this grapple ends, the creature is restrained, and the snake can't constrict another target.
The snake hisses loudly and every creature within 60 ft. must make a DC 16 Wisdom saving throw. If a target fails the saving throw, they are paralyzed until the end of the snake's next turn.
