Naturally Psionic: Telepathic cubes gain 1 bonus power point at 1st level. This benefit does not grant them the ability to manifest powers unless they gain that ability through another source, such as levels in a psionic class.
Acid (Ex): A telepathic cube’s acid does not harm metal or stone.
Engulf (Ex): Although it moves slowly, a telepathic 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 attacks of opportunity must succeed on a Reflex save (DC11 + 1/2 HD + Strength modifier) 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): A telepathic cube secretes an anesthetizing slime. A target hit by a cube’s melee or engulf attack must succeed on a Fortitude save (DC10 +1/2 HD + Constitution modifier) or be paralyzed for 3d6 rounds. The cube can automatically engulf a paralyzed opponent.
Transparent (Ex): Telepathic cubes are hard to see, even under ideal conditions, and it takes a DC 15 Spot check to notice one. Creatures who fail to notice a cube and walk into it are automatically Engulfed.
Favored Class: Psion
Level Adjustment: +1
