False Appearance. When motionless, the rock troll is indistinguishable from a typical boulder.
Regeneration. The rock troll regains 10 hit points at the start of its turn. If the rock troll takes thunder or cold damage, this trait doesn’t function on its next turn. The rock troll dies only if it starts its turn with 0 hit points and doesn’t regenerate.
Severed Limbs. If the rock troll is dealt a critical hit with a slashing weapon, one of its extremities is severed. The extremity has AC 15, 10 hit points, a Speed of 10, and the rock troll's Regeneration trait. The rock troll controls the severed extremity and perceives through it with the appropriate senses (for instance, it sees through the eyes of its severed head). As a bonus action, the rock troll can reattach the extremity. While the rock troll is missing the extremity, its maximum hit points are reduced by 10. Roll d6 to determine the severed extremity:
1-4: Arm. If the rock troll has an arm, it loses an arm. It loses one of its claw attacks, and the severed arm can make a claw attack.
5-6: Head. If the rock troll has a head, it loses its head. It loses its bite attack, and the severed head can make a bite attack.
ACTIONS
Multiattack. The rock troll attacks with its bite and twice with its claw.
Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) piercing damage.
Claw. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 9 (2d4 + 4) slashing damage.
Ambushing Shove. The rock troll targets one Large or smaller creature within reach that either has not taken a turn in the combat yet, is within 5 feet of another enemy, or against whom the rock troll has advantage . The target makes a DC 14 Strength saving throw . On a failure, the rock troll shoves the target up to 30 feet horizontally and knocks it prone . If the target strikes an object, such as a wall, it takes 10 (3d6) bludgeoning damage. If the target would strike another creature, that creature must succeed on a DC 14 Dexterity saving throw or both take the same damage and are knocked prone.
Combat
The troll ambushes prey and attacks the closest or slowest opponent, ignoring all damage except fire and acid. It flees only if it’s bloodied , it has taken acid or fire damage, and none of its enemies are down.

Legends and Lore
With an Arcana or Nature check, characters can learn the following:
DC 10 A troll’s unique physiology allows it to heal wounds with incredible speed. Fire and acid temporarily suppress this regeneration.
DC 15 Though large, trolls are quite stealthy. They can see in the dark and track prey by smell alone.
DC 20 Because of their regeneration, trolls are prone to mutation. Certain strains have adapted to life underground or deep beneath the waves.
Some trolls take to the tallest passes, developing a weathered, rocky appearance. These changes protect them from a troll’s typical weaknesses, and close quarters have taught them to ambush prey, often flinging the unwary off cliffs.
