Stone Giant

Camouflage. The giant has advantage on Stealth checks made to hide in rocky terrain.

Multiattack. The giant attacks twice with its greatclub or twice with rocks.

Greatclub. Melee Weapon Attack: +9 to hit, reach 15 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage. If the target is a Large or smaller creature it makes a DC 19 Strength saving throw falling prone on a failure.

Rock. Ranged Weapon Attack: +9 to hit, range 60/240 ft., one target. Hit: 20 (4d6 + 6) bludgeoning damage. If the target is a Large or smaller creature it makes a DC 19 Strength saving throw. On a failure it is pushed 10 feet away from the giant and knocked prone. In lieu of a rock the giant can throw a grappled Medium or smaller creature up to 30 feet. On a hit the target and the thrown creature both take 15 (3d6 + 5) bludgeoning damage. On a miss only the thrown creature takes the damage. The thrown creature falls prone in an unoccupied space 5 feet from the target.

Grab. One creature within 5 feet makes a DC 13 Dexterity saving throw. On a failure, it is grappled (escape DC 17). Until this grapple ends, the giant can't grab another target, and it makes greatclub attacks with advantage against the grappled target.

Rock Catching. If a rock or other Small or larger projectile is hurled or fired at the giant, the giant makes a DC 10 Dexterity saving throw. On a success, the giant catches the projectile, takes no bludgeoning or piercing damage from it, and is not pushed or knocked prone by it.
