SPECIAL ABILITIES

Acid (Ex)

A gelatinous cube’s acid does not harm metal or stone.

Electric Pulse (Ex)

Once every 1d4 rounds, the ooze can generate an electric pulse in a 10-foot radius that deals 1d8 points of electricity damage and stuns creatures for 1 round. A DC 20 Fortitude save reduces the damage by half and negates the stunning effect.

Engulf (Ex)

Although it moves slowly, a gelatinous cube can simply engulf Large or smaller creatures in its path as a standard action. It cannot make a slam attack during a round in which it engulfs. The gelatinous cube merely has to move over the opponents, affecting as many as it can cover. Opponents can make attacks of opportunity against the cube, but if they do so they are not entitled to a saving throw. Those who do not attempt attacks of opportunity can attempt a DC 12 Reflex save to avoid being engulfed—on a success, they are pushed back or aside (opponent’s choice) as the cube moves forward. Engulfed creatures are subject to the cube’s paralysis and acid, gain the pinned condition, are in danger of suffocating, and are trapped within its body until they are no longer pinned. The save DC is Strength-based.

Paralysis (Ex)

A gelatinous cube secretes an anesthetizing slime. A target hit by a cube’s melee or engulf attack must succeed on a DC 20 Fortitude save or be paralyzed for 3d6 rounds. The cube can automatically engulf a paralyzed opponent. The save DC is Constitution-based.

Partially Transparent (Ex)

Unlike its more common transparent cousin, an electric gelatinous cube has a purplish sheen, making it somewhat easier to detect. A DC 10 Perception check is required to notice a motionless electric gelatinous cube. Any creature that fails to notice an electric gelatinous cube and walks into it is automatically engulfed.
