Regeneration. 682 regains 10d8 hit points at the start of its turn. If 682 takes acid damage, this trait doesn't function at the start of 682's next turn. The troll dies only if it starts its turn with 0 hit points and doesn't regenerate.

Multiattack. 682 can use its Frightful Presence. It then makes five attacks: one with its bite, two with its claws, and one with its tail. It can use its Swallow instead of its bite.

Bite. Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 36 (4d12 + 10) piercing damage. If the target is a creature, it is grappled (escape DC 20). Until this grapple ends, the target is restrained, and 682 can’t bite another target.

Claw. Melee Weapon Attack: +19 to hit, reach 15ft., one target. Hit: 28 (4d8 + 10) slashing damage.

Tail. Melee Weapon Attack: +19 to hit, reach 20ft., one target. Hit: 24 (4d6 + 10) bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be knocked prone.

Scary Presence. Each creature of 682’s choice within 120 feet of it and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if 682 is within line of sight, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the 682s Frightful Presence for the next 24 hours.

Big Gulp. 682 makes one bite attack against a medium or smaller creature it is grappling. If the attack hits, the target takes the bite’s damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the 682, and it takes 56 (16d6) acid damage at the start of each of the 682s turns.

If 682 takes 60 damage or more on a single turn from a creature inside it, 682 must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of 682. If 682 dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.
