Out of the dark and into the light, a shimmering of scintillating colors appear on a creature of immense size and formed like a cube, its moves sway and shift like jello as it moves towards you.
This creature was a by-product of a horrible experiment from a wizard, it still retains its gelatinous effects and movement, however, it is infused with a prismatic effect. A creature with immense defense and attack.
Combat: Still retaining its previous gelatinous cube forms and attacks, but in its new form of prismatic effects its more a confident cube.
Acid: A gelatinous cube's acid does not harm metal or stone.
Engulf: 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 a saving throw. Those who do not attempt opportunity attacks, must succeed on a DC 13 reflex save or be engulfed; on a successful save they are pushed back or aside as the cube moves forward. Engulfed creatures are subject to the cubes paralysis and acid, and are considered to be grappled and trapped within its body. The save DC is strength based and includes a +1 racial bonus.
Paralysis: A gelatinous cube secretes an anesthetizing slime. A target hit by a cubes 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 DC is constitution based.
Prismatic Attack: In addition to the paralysis, any creature that is hit by the prismatic gelatinous cubes melee attack is subject to a prismatic spray effect attack. (The effects are explained in the PHB 264).
Prismatic Defense: A prismatic gelatinous cube is encased or rather made of prismatic colors, and is treated to have the Prismatic Spray spell feature. Any creature attempting to attack the prismatic gelatinous cube is subjected to the prismatic Spray spell. (PHB 264)
Blindness: Any creature coming within 20ft of the cube that is 8HD or less is automatically blinded for 2D4 rounds.
