Charging Giant

Charge. If the giant moves at least 15 feet straight toward a target and then hits it with a fist attack on the same turn, the target takes an extra 13 (3d8) bludgeoning damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or be pushed up to 15 feet away and knocked prone.

Unusual Nature. The giant doesn’t require air, drink, or sleep. It can survive without food for months, or years if hibernating. It will go into hibernation if it is unable to roam or no food is accessible for an extended period of time.

Multiattack. The giant makes one fist attack and one grapple. The giant has only two fists, so it can grapple only two targets at time.

Fist. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 12 (3d4 + 5) bludgeoning damage.

Swallow. The giant makes an Athletics check contested by an Athletics or an Acrobatics check by a Medium or smaller target that is grappled by the giant. If the giant succeeds, the target is swallowed. In either case the grapple ends.

While swallowed, the target is blinded and restrained, it has total cover against attacks and other effects outside the giant, it takes 10 (3d6) acid damage at the start of each of the giant's turns, and the giant regenerates hit points equal to the dealt acid damage. A giant can have only one creature swallowed at a time.

If the giant takes 15 damage or more on a single turn from the swallowed creature, the giant must succeed on a DC 15 Constitution saving throw at the end of that turn or regurgitate the creature, which falls prone in a space within 10 feet of the giant. If the giant dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 10 feet of movement, exiting prone.
