Traits

Rock Camouflage. Advantage on Hide checks on rocky terrain; light cover is enough. Ambush Killer. Its first attack from Hidden deals 14 (4d6) extra damage. Sure-Footed. Doesn't provoke Opportunity Attacks while climbing.

Actions

Multiattack. Two Claw attacks. Claw. Melee Attack Roll: +7, reach 5 ft. Hit: 13 (2d8 + 4) Slashing damage. Hurl Boulder. Ranged Attack Roll: +7, range 60/120 ft. Hit: 17 (3d8 + 4) Bludgeoning damage. The target makes a DC 15 STR save; on a failure, Prone. Shove Off Cliff. Melee Attack Roll: +7, reach 5 ft. Hit: 9 (1d10 + 4) Bludgeoning damage, and the target makes a DC 15 STR save. Failure: Pushed 15 feet. If it's at the edge of a cliff, it falls (fall damage!).

Bonus Actions

Scale. Moves at Climb speed and takes the Hide action.

Key

Stay away from cliff edges (Shove Off Cliff is lethal!), and get to open terrain.
