Aberrant Ground: The ground in a 10-foot radius around the mouther is doughlike difficult terrain. Each creature that starts its turn in that area must succeed on a DC 10 Strength saving throw or have its speed reduced to 0 until the start of its next turn.

Gibbering: The mouther babbles incoherently while it can see any creature and isn't incapacitated. Each creature that starts its turn within 20 feet of the mouther and can hear the gibbering must succeed on a DC 10 Wisdom saving throw. On a failure, the creature can't take reactions until the start of its next turn and rolls a d8 to determine what it does during its turn. On a 1 to 4, the creature does nothing. On a 5 or 6, the creature takes no action or bonus action and uses all its movement to move in a randomly determined direction. On a 7 or 8, the creature makes a melee attack against a randomly determined creature within its reach or does nothing if it can't make such an attack.


Multiattack: The gibbering mouther makes one bite attack and, if it can, uses its Blinding Spittle.

Bites: Melee Weapon Attack: +2 to hit, reach 5 ft., one creature. Hit: 17 (5d6) piercing damage. If the target is Medium or smaller, it must succeed on a DC 10 Strength saving throw or be knocked prone. If the target is killed by this damage, it is absorbed into the mouther.

Blinding Spittle (Recharge 5-6): The mouther spits a chemical glob at a point it can see within 15 feet of it. The glob explodes in a blinding flash of light on impact. Each creature within 5 feet of the flash must succeed on a DC 13 Dexterity saving throw or be blinded until the end of the mouther's next turn.

The SendingStone review

The Gibbering Mouther is a unique and challenging monster in the world of Dungeons and Dragons. Despite its low charisma and intelligence stats, this creature's primal abilities and condition immunities make it a formidable foe for any adventurer. Its gurgling gibberish can cause confusion and madness in those who hear it, and its multiple attacks can quickly overwhelm a party. Additionally, the Gibbering Mouther can regenerate lost body parts and split into multiple smaller versions of itself, making it nearly impossible to defeat without careful planning and strategy. Overall, the Gibbering Mouther is a fantastic addition to any dungeon master's repertoire of monsters, providing an unforgettable experience for players who encounter it.

Gibbering Mouther is D&D (Dungeons & Dragons) 5th edition content, but other TTRPGs may have their own version such as a Gibbering Mouther Pathfinder edition. Want to use Gibbering Mouther in a VTT (virtual tabletop)? Try out SendingStone for free today!
