Up to three targets of Huge size or smaller within 10 feet of Tsathogga must make a DC 27 Dexterity saving throw. On a successful saving throw, it takes 44 (10d6 + 9) piercing damage, plus 35 (10d6) acid damage, and is grappled. On a failed saving throw, the target is swallowed. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside of Tsathogga, and it takes 56 (16d6) acid damage at the start of each of Tsathogga's turns. If Tsathogga takes 50 damage or more on a single turn from a creature inside it, Tsathogga must succeed on a DC 25 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space with 10 feet of Tsathogga. If Tsathogga dies, a swallowed creature is no longer restrained by it and can escape from the corpse using all of its movement, exiting prone.
