Homebrew Gibbering Mouther (Revised) Species Details

"It was horrible in every conceivable definition of the word. The way it moved. The way it looked. The way it smelled. But the sounds it made? Pure nightmare fuel"

—Eli'i, the only survivor

 

Of all the terrors created by foul sorcery, gibbering mouthers are among the most wicked and depraved. This creature is the composite eyes, mouths, and liquefied matter of its former victims. Driven to insanity by the destruction of their bodies and absorption into the mouther, those victims gibber incoherent madness, forced to consume everything in reach.

Amoeboid Form. The gibbering mouther's body is an amorphous mass of mouths and eyes that propels itself by oozing forward, fastening several mouths to the ground and pulling its bulk behind. Though it moves slowly, it swims through water, mud, and quicksand with ease. To blend in, particularly old and intelligent mouthers mold themselves into a humanoid shape, covering their various mouths and eyes under layers of clothing.

Mouths of Madness. When a gibbering mouther senses prey, its mouths begin to murmur and chatter, each with a different voice: deep or shrill, wailing or ululating, crying out in agony or ecstasy. This cacophonous gibbering overcomes the senses of any creature that hears it, causing most to flee in terror. Others are overcome with madness or stand paralyzed, fixated on the horrific creature as it oozes forward to consume them.

All-Consuming. Driven to devour any creature it can reach, a gibbering mouther flows over victims transfixed by its mad ranting, its multitudinous voices temporarily silenced as it gnaws and swallows living flesh. The monster liquefies stone with which it comes into contact, hindering creatures that overcome its gibbering and attempt to flee.
A gibbering mouther leaves nothing of its prey behind. However, even as the last of a victim's body is consumed, its eyes and mouth boil to the surface, ready to join the chorus of tormented gibbering that welcomes the monster's next meal.

Your gibbering mouther has the following traits.

Ability Score Increase

Your Constitution score increases by 2, and your Wisdom score increases by 1.

Age

Mouthers live as long as they can consume. If they haven't eaten in a certain amount of days equal to their CON modifier, they begin to consume themselves, collapse and rot away.

Alignment

The mouther knows nothing of good or evil. Only the drive to consume. Their maddening presence breeds chaos itself.

Speed

Your base walking speed is 10 feet. Using a humanoid form is extremely laborious. Your footsteps are heavy and slow.

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 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.
