Description

Disgusting, loathsome, and hungry—these are the only words that properly describe the gibbering mouther. A foul beast that lurks in underground caves, sewers, and nightmares, mouthers have no societal, ecological or religious significance other than their ability to drive those that listen to them mad. Some scholars believe that gibbering mouthers are a lesser variant of the much more dangerous shoggoth, while others theorize they are a punishment by some powerful being or deity inflicted on those who have offended it.

Special Attacks

Blood Drain — On a successful grapple check after grabbing, several of the creature's mouths attach to its target. Each round it maintains its grapple, its mouths automatically deal 1d4 points of bite damage and 1 point of Constitution damage as it drains its victim's blood.

Engulf — This ability functions as swallow whole, except for the following changes. An engulfed creature is trapped in the gibbering mouther's body, where several of its mouths continue to feed and drain blood. A gibbering mouther can engulf only one foe of its size or smaller at a time. If an engulfed creature cuts its way free (the mouther's damage reduction still applies to those inside), the mouther simply flows together again and can still use its engulf attack.

Gibbering — As a free action, a gibbering mouther can emit a cacophony of maddening sound. All creatures other than gibbering mouthers within 60 feet must succeed on a DC 13 Will save or be confused for 1 round. This is a mind-affecting compulsion insanity effect. A creature that saves cannot be affected by the same mouther's gibbering for 24 hours. The save DC is Constitution-based.

Ground Manipulation — At will as a standard action, a gibbering mouther can cause stone and earth under its body to grow soft and muddy. The ground remains muddy for 1 minute after the mouther moves off of the location. A gibbering mouther can move through these areas with ease, but other creatures treat them as difficult terrain.

Spittle — Each round as a free action, a gibbering mouther can emit a stream of acidic spittle at one target within 30 feet. On a successful attack, the target is blinded for 1d4 rounds unless he succeeds on a DC 18 Fortitude save. The save DC is Constitution-based.

Special Abilities

Universal Monster Rules

Amorphous Ex from Universal Monster Rule

The creature's body is malleable and shapeless. It is immune to precision damage (like sneak attacks) and critical hits.

Blood Drain Ex from Universal Monster Rule

The creature drains blood at the end of its turn if it grapples a foe, inflicting Constitution damage.

Engulf Ex from Universal Monster Rule

The creature can engulf creatures in its path as part of a standard action. It cannot make other attacks during a round in which it engulfs. The creature merely has to move over its opponents, affecting as many as it can cover. Targeted creatures can make attacks of opportunity against the creature, but if they do so, they are not entitled to a saving throw against the engulf attack. Those who do not attempt attacks of opportunity can attempt a Reflex save to avoid being engulfed—on a success, they are pushed back or aside (target's choice) as the creature moves forward. Engulfed opponents gain the pinned condition, are in danger of suffocating, are trapped within the creature's body until they are no longer pinned, and may be subject to other special attacks from the creature. The save DC is Strength-based.

Grab (bites) Ex from Universal Monster Rule

If a creature with this special attack hits with the indicated attack (usually a claw or bite attack), it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply to use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its combat maneuver check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature's descriptive text). Creatures with grab receive a +4 bonus on combat maneuver checks made to start and maintain a grapple. Unless otherwise noted, grab works only against opponents no larger than the same size category as the creature. If the creature can use grab on sizes other than the default, this is noted in the creature's Special Attacks line.
