Aquatic Ooze
CREATURE 4Variant gray ooze
These dangerous oozes are the bane of any who travel through swamps, marshes, or damp caves. Easily masquerading as pools of clear water or patches of wet stone, gray oozes lie in wait for unwary victims to reach down for a drink or step into what appears to be a puddle, then lash out with whiplike pseudopods to ensnare and consume their hapless prey.
A gray ooze can sense nearby creatures through vibration and air or water movement.
1d6 bludgeoning plus 1d6 acid, DC 21 basic Fortitude
The monster deals the listed amount of damage to any number of creatures Grabbed or Restrained by it. Each of those creatures can attempt a basic Fortitude save with the listed DC.
A gray ooze's acid damages only metal and organic materials, not stone.
A creature hit by the ooze's pseudopod is Paralyzed unless it succeeds at a DC 19 Fortitude save. A victim can attempt a new save to recover at the end of each of its turns.
The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
