Actions
Multiattack. The grootslang makes four attacks: one with its gore, two with its stomp and one with either constrict or its tail slap.
Gore. Melee Weapon Attack: , reach 20 ft., one target. Hit: piercing damage.
Constrict. Melee Weapon Attack: , reach 20 ft., one target. Hit: bludgeoning damage. The target is grappled (escape DC 25) if the grootslang isn't already constricting a creature, and the target is restrained until the grapple ends. While grappling the target, the grootslang has advantage on attack rolls against it and can't use this attack against other targets. When the grootslang moves, any target it is grappling moves with it.
Stomp. Melee Weapon Attack: , reach 20 ft., one target. Hit: slashing damage.
Tail Slap. Melee Weapon Attack: , reach 20 ft., one target. Hit: bludgeoning damage.
Legendary Actions

Rolling Death Cradle (Costs 2 Actions). The grootslang writhes about, crushing any creatures in close proximity. Each creature within 20 feet of the grootslang must succeed on a DC 25 Dexterity saving throw or take bludgeoning damage and be knocked prone. A creature grappled by the grootslang automatically takes a critical hit. The grootslang can finish its movement a distance up to half its speed away.
