Special abilities

• Aberrant Ground. The ground within 10 feet of the mouther is dough-like difficult terrain. A creature that starts its turn in the area must succeed on a DC 13 STR save or its speed is halved until the start of its next turn.
• Aberrant Resilience. The mouther is resistant to the charmed, frightened, paralyzed, and stunned conditions, and it has advantage on saves against spells or effects that would alter its form.
• Gibbering. The mouther babbles incoherently while it can see any creature and isn't incapacitated. A creature that starts its turn within 20 feet of the mouther and that can hear the gibbering must succeed on a DC 13 WIS save or it can't take reactions until the start of its next turn and must roll 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 moves its full speed 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.
