Ooze: Immune to mind-influencing effects, poison, sleep,
paralysis, stunning, and polymorphing. Not subject to critical
Blindsight (Ex): An ooze's entire body is a primitive
sensory organ that can ascertain prey by scent and vibration
within 60 feet.
Engulf (Ex): Although it moves slowly, a gelatinous cube can
simply mow down Large or smaller creatures 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 opportunity
attacks against the cube, but if they do so they are not entitled
to a saving throw. Those who do not attempt opportunity attacks
must succeed at a Reflex save (DC 13) or be 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, and are considered to be grappled
and trapped within its body.
Paralysis (Ex): Gelatinous cubes secrete an anesthetizing
slime. A target hit by a cube's melee or engulf attack must
succeed at a Fortitude save (DC 16) or be paralyzed for 3d6
rounds. The cube can automatically engulf a paralyzed opponent.
Acid (Ex): A gelatinous cube's acid does not harm metal
Transparent (Ex): Gelatinous cubes are hard to see, even under
ideal conditions, and it takes a successful Spot check (DC 15) to
notice one. Creatures who fail to notice a cube and walk into it
are automatically engulfed.
