Paralysis (Ex): The attack of a ghaunadan in ooze form can paralyze its opponent. The victim must make a Fortitude save (DC 13) or be paralyzed for 2d6x10 minutes.

Charming Gaze (Su): In humanoid form, a ghaunadan has a gaze attack: Characters who meet the ghaunadan's gaze must make a Will save (DC 15). Those who fail this saving throw regard the ghaunadan as if its Charisma were 2d4 points higher This ability is useless in combat, but allows the ghaunadan to make excellent use of its Charisma-based skills (Bluff, Diplomacy, and Disguise). The effect lasts as long as the ghaunadan is in sight and remains in humanoid form.

Resist Blunt Weapons (Ex): A ghaunadan's semi-liquid body takes only half damage from bludgeoning weapons.

Disarm (Ex): In its ooze form, a ghaunadan can forego all attacks in a round and choose to mold itself around an opponent's weapon; when a successful attack hits the ghaunadan, the weapon sinks into its mass, but the ghaunadan then firms its skin around the weapon, trapping it. A character can make a Strength check (DC 20) to free the weapon.

Blindsight (Ex): As an ooze-like creature, a ghaunadan has no eyes, but its whole body acts as a sensory organ, allowing it to perceive its environment out to a range of 60 feet.

Immunities (Ex): Ghaunadans share many of the immunities of oozes, though they do have minds and Intelligence scores. They are immune to poison, sleep, paralysis, stunning, and polymorphing. They are not subject to critical hits, and cannot be flanked. These immunities apply in both humanoid and ooze form.

In ooze form, a ghaunadan lashes out with two pseudopods, dealing bludgeoning damage and coating its victim with paralytic slime. In humanoid form, the creature prefers to use weapons, but it can use a move-equivalent action to form its hands into pseudopods and then attack normally.
