Bloated Gastromorph

Spider Climb. The Bloated Gastromorph can slither up walls and across ceilings.

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

Multiattack. The Bloated Gastromorph makes three attacks. It only makes bite attacks against enemies it has grappled.

Claws. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 16 (3d8 + 3) bludgeoning damage, and the target is grappled (escape DC 16) and is moved up to 5 feet toward the Bloated Gastromorph.

Action Ranged Attack. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 25 (4d10 + 3) piercing damage. If the target is a Large or smaller creature grappled by the Gastromorph, that creature is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside of the Gastromorph, and it takes 21 (6d6) acid damage at the start of each of the Bloated Gastromorph’s turns.

If the Bloated Gastromorph takes 40 damage or more from a single source, then all swallowed creatures are ejected from the Gastromorph. They fall prone in a space within 10 feet of the Gastromorph. If the Bloated Gastromorph dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 15 feet of movement, exiting prone.

Tongue (Recharge 5-6). Melee Weapon Attack: +7to hit, reach 25 ft., one target. Hit: 15 (2d12 + 3) poison damage. A creature that is hit by this attack must succeed a DC 14 Constitution saving throw or become paralyzed. A creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
