||This horrid mass of eyes, mouths, and formless flesh stares in all directions, its countless maws yammering ceaselessly. 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.
A gibbering mouther sees in all directions at once. It cannot be flanked.
A gibbering mouther’s body is malleable and shapeless. It is immune to sneak attacks, and can move through an area as small as one-eighth its SIZ.
On a successful grapple check after grabbing, several of the creature’s mouths attach to its target. Each new round it maintains its grapple, its mouths automatically deal 1 level of blood loss and 1 point of Constitution damage as it drains its victim’s blood, on top of any damage inflicted by the grapple.
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 resistance and AP still applies to those inside), the mouther simply flows together again and can still use its engulf attack.
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 an opposed WILL roll vs the mouthers influence skill or be confused for 1 round. As this is a insanity effect if the rules are used each unresisting gibber causes 1d3 sanity loss. The mouther can do this once every round.
Die Roll Effects
01-10 Act normally for 1 Round
11-20 Attack the caster or the caster’s allies for 1 Round
21-50 Stop in place and babble incoherently for 1 Round
51–65 Deal weapon damage + DAM modifier to self with item in hand (random location) then mew in pain for rest of round.
66-75 Meander away from the caster for Intensity in rounds (no resistance rolls allowed in this time)
76-00 Attack the nearest creature for 1 Round
As an 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.
Each round on its action but counted as a 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 an opposed END roll vs the spittle attack.
Lose of mouths reduced its attacks by 1 per 2 lost, and attacks that would strike a mouth that is missing strike the body instead. It never loses its body mouths, only its Pseudopod ones.
