Special Abilities

Acid (Ex) A gelatinous cube’s acid does not harm metal or stone.

Adherence (Ex) Weapons that strike a mythic gelatinous cube become stuck to it if the wielder fails a DC 20 Reflex save. Creatures attacking the cube with natural weapons, unarmed strikes, or melee touch attacks must likewise save or become stuck fast. Creatures stuck to the cube take a -4 penalty to saving throws against its engulf attack. The save DC is Constitution-based.

Silent Slider (Ex) The DC to notice a mythic gelatinous cube is increased by 5 (see its transparent ability), and this DC is not reduced by the cube’s movement. In addition, a mythic gelatinous cube takes no penalties for squeezing into or through spaces at least 5 feet wide.

Transparent (Ex) Due to its lack of coloration, a mythic gelatinous cube is difficult to discern. A DC 20 Perception check is required to notice a motionless mythic gelatinous cube. Any creature that fails to notice a mythic gelatinous cube and walks into it is automatically engulfed.
