Special Abilities

All-Around Vision (Ex) A mythic gibbering mouther sees in all directions at once. It cannot be flanked.

Amorphous (Ex) A mythic gibbering mouther’s body is malleable and shapeless. It is immune to precision damage (like sneak attacks) and critical hits, and can move through an area as small as one-quarter its space without squeezing or one-eighth its space when squeezing.

Beckoning Gibber (Su) Creatures beginning their turn within 120 feet of a mythic gibbering mouther while it is gibbering are must succeed on a DC 13 Will save each round or be compelled to spend a move action moving toward it. Confused creatures that are compelled to take no action or to attack themselves automatically fail their save against this effect during that round.

Blood Drain (Ex) 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+4 points of bite damage and 1 point of Constitution damage as it drains its victim’s blood.

Caustic Spittle (Ex) Each round as a free action, a mythic 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 19 Fortitude save and takes 1d6 acid damage this round and the next round. The save DC is Constitution-based. This ability replaces the spittle ability of a normal gibbering mouther.

Enduring Insanity (Su) When a creature is confused by a mythic gibbering mouther’s gibbering ability, the mouther may expend one use of its mythic power to extend the duration of that creature’s confusion to 1 minute instead of 1 round. A creature targeted with this ability cannot be affected by this ability more than once per day by the same mythic gibbering mouther.

Engulf (Ex) 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 (Su) 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 Charisma-based.

Ground Manipulation (Su) 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.
