Bloated. If the Herald of Tsathogga attacks with more than four tentacles during a single turn, its movement speed is reduced to 0 and it falls prone. The herald can use half its movement on its next turn to rise from the prone position.

Regeneration. The Herald of Tsathogga regains 20 hit points at the start of its turn. If the herald takes fire or lightning damage, this trait doesn’t function at the start of the herald’s next turn. The herald dies only if it starts its turn with 0 hit points and doesn’t regenerate.

Actions

Multiattack. The Herald of Tsathogga makes up to twelve attacks: one with its bite or swallow, one with its tongue, and it can make one attack with each of its ten tentacles.

Bite. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) piercing damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained and the herald can’t bite another target.

Tongue. Melee Weapon Attack: +12 to hit, reach 30 ft., one target. Hit: 12 (1d12 + 6) slashing damage plus 9 (2d8) acid damage, and the target must succeed on a DC 16 Strength saving throw or be pulled up to 25 feet toward the Herald.

Tentacle. Melee Weapon Attack: +12 to hit, reach 20 ft., one target. Hit: 10 (1d8 + 6) bludgeoning damage. If the target is a creature other than an undead, it must succeed on a DC 19 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Swallow. The Herald of Tsathogga makes one bite attack against a Large or smaller target it is grappling. If the attack hits, the target is swallowed and the grapple ends. The swallowed target is blinded and restrained, has total cover against attacks and other effects outside of the herald, and it takes 21 (6d6) acid damage at the start of each of the herald’s turns. The herald can have only one target swallowed at a time.

If the herald takes 50 damage or more on a single turn from the swallowed creature, the herald must succeed on a DC 15 Constitution saving throw at the end of that turn or forcefully disgorge the creature, which falls prone in a space within 20 feet of the herald. If the herald dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 15 feet of movement, exiting prone.

Bellow (Recharge 5–6). The Herald of Tsathogga emits a deafening, trilling croak. All creatures within 30 feet of the herald that can hear it must make a DC 19 Constitution saving throw, taking 28 (8d6) thunder damage on a failure, or half as much damage on a successful save. On a failed save, the creature is also deafened for 1 minute. A deafened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
