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. \n'b'  Gibbering . The mouther babbles incoherently while it can see any creature and isn\xe2\x80\x99t  incapacitated . Each creature that starts its turn within 20 feet of the mouther and can hear the gibbering must succeed on a DC 12  Wisdom  saving throw. On a failure, the creature can\xe2\x80\x99t 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\xe2\x80\x99t make such an  attack . \n'b'  Magic Resistance . The mouther has advantage on saving throws against spells and other magical effects. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The gibbering mouther makes three bite attacks and, if it can, uses its Blinding Spittle. \n'b'  Bite .  Melee Weapon Attack : +7 to hit, reach 5 ft., one creature.  Hit : 21 (5d6 + 4) necrotic damage. If the target is Medium or smaller, it must succeed on a DC 15  Strength  saving throw or be forced  prone . If the target is killed by this damage, it is absorbed into the mouther. \n'b'  Blinding Spittle (Recharge 5-6) . The mouther spits a chemical glob at a point it can see within 25 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 14  Dexterity  saving throw or be  blinded  until the end of the mouther\xe2\x80\x99s next turn. \n'b'  Engulf . The mouther moves up to its speed. While doing so, it can enter Large or smaller creatures\xe2\x80\x99 spaces. Whenever the mouther enters a creature\xe2\x80\x99s space, the creature must make a DC 14  Dexterity  saving throw. On a successful save, the creature can choose to be pushed 5 feet back or to the side of the mouther. A creature that chooses not to be pushed suffers the consequences of a failed saving throw. On a failed save, the mouther enters the creature\xe2\x80\x99s space, and the creature takes 10 (3d6) necrotic damage and is engulfed. The engulfed creature can\xe2\x80\x99t breathe, is  restrained , and takes 21 (6d6) necrotic damage at the start of each of the mouther\xe2\x80\x99s turns. When the mouther moves, the engulfed creature moves with it.'
