Transparent A gelatinous cube is so clear that it's difficult to spot. A successful DC 23 Perception check is required to notice a stationary cube, and a creature must be Searching to attempt this check. A creature that walks into the cube is automatically Engulfed (this usually causes the GM to call for initiative).

Paralysis (incapacitation) A creature Engulfed by the cube or hit by its attack is paralyzed unless it succeeds at a DC 20 Fortitude save. A victim can attempt a new save to recover at the end of each of its turns.
Weak Acid A gelatinous cube's acid damages only organic material—not metal, stone, or other inorganic substances.
Found underground or in dungeons, these quivering cubes of slime continuously scour their domain for food. The acid in their bodies is weak enough that many gelatinous cubes still contain the gear of their victims, as they're unable to break them down.
