Gibbering mouthers are amorphous aberrations with many mouths and eyes.

Description

These creatures are made out of the liquefied composite flesh of their former victims, incorporating more-solid eyes and teeth.

Abilities

All these abilities are taken from the Monster Manual (2014), p. 157:

• Condition immunities: Prone
• Aberrant Ground: The ground around a gibbering mouther is soft, difficult terrain requiring other creatures to make a Strength saving throw to continue moving
• Gibbering: While the mouther can see any creature and is not incapacitated, it babbles incoherently. Each creature that starts its turn within 20 feet of the mouther must succeed at a Wisdom saving throw or lose its reactions and randomly determine how it spends its turn: doing nothing, moving in a random direction, or making a melee attack against a random creature in its reach.
• Actions:
  • Blinding Spittle (recharge 5/6): Spits at a point within 15 feet; each creature within 5 feet must succeed at a Dexterity saving throw or be blinded until the end of the mouther's next turn.
  • Bites: Deals piercing damage. If the target is Medium or smaller, it must succeed at a Strength saving throw or fall prone. If this damage kills the creature, the mouther absorbs the creature.
  • Multiattack: Makes one Blinding Spittle (if recharged) and one Bites attack.

History

Official art of Aurora Watch guards fighting a gibbering mouther in the streets of Bazzoxan, by Robson Michel.

Gibbering mouthers are created by demons in the Betrayers' Rise, and they are a common threat in Bazzoxan.

In Call of the Netherdeep, the Player Characters' (PCs') first encounter upon entering Bazzoxan is an attack by gibbering mouthers who have snuck into the settlement. Verin Thelyss and troops of the Aurora Watch he commands leap into action to fend them off, with the aid of Ayo Jabe's adventuring party if they are with the PCs. Jabe's party must recuperate at the infirmary, and Jabe herself may be badly wounded, to the dismay of her party. One scout named Naevyn Tasithar is covered in wounds and must also recover at the infirmary.

Inside the Betrayers' Rise, just past the first internal door, is a hall with many inch-wide holes drilled into its walls; these holes emit a snoring sound. As the PCs pass, streams of liquid flesh, teeth, and eyes pour from the holes, reform into three mouthers, and attack the PCs.
