Chain Giant

Multiattack. The giant can use its two chains to make a chain or fling attack with each.

Chain. Melee Weapon Attack: +9 to hit, reach 20 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage. If the target is a creature, it is grappled (escape DC 17). Until the grapple ends, the target is restrained, and the giant can’t use this chain on anyone else.

Fling. The giant makes one attack using a creature it is grappling in its chain. The target must make a dexterity saving throw (DC 17). On a failed save, the target and the grappled creature each take 2d8 bludgeoning damage and are knocked prone. On a successful save, the target and the grappled creature take half as much damage and the target is not knocked prone, the grappled creature is knocked prone.

Chain smash. The giant slams two creatures grappled in its chains together, each grappled creature makes a dexterity saving throw (DC 17). On a failed save, the grappled creature takes 4d8 bludgeoning damage and is knocked prone. On a successful save, a creature takes half as much damage and is still knocked prone.

Rock. Ranged Weapon Attack: +9 to hit, range 60/240 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage.

Chain Defense. After a creature within 20 feet of the giant deals damage to the giant, the giant makes a chain or fling attack against that foe.
