  • False Appearance. While the livestone is solidified and remains motionless, it is indistinguishable from a typical stone.
  • Stone Camouflage. The livestone has advantage on Dexterity (Stealth) checks made to hide in rocky terrain.


  • Multiattack. The livestone makes two Slam attacks.
  • Slam. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage, and the target is grappled (escape DC 15).
  • Engulf. The livestone engulfs a Medium or smaller creature grappled by it. The engulfed target is blinded, restrained, and unable to breathe, and it must succeed on a DC 15 Constitution saving throw at the start of each of the livestone’s turns or take 14 (2d8 + 5) bludgeoning damage. If the livestone moves, the engulfed target moves with it. The livestone can have only one creature engulfed at a time.


  • Solidify. As a reaction, the livestone can solidify all or part of itself into material with the same consistency of solid rock. The livestone adds 4 to its Armor Class against one melee attack that would hit it. The livestone does not have to see the attack to use this ability. A livestone cannot take attack or move actions if its entire form is solidified.


Looking all the world like a boulder or chunk of rock, livestone is an ooze from deep in the earth that has, sadly, been brought to the surface. It can solidify itself and mimic the color and texture of nearby stone, granting it a near-perfect camouflage. In this state, it can hibernate for years between meals. Once roused, it moves to roll over prey and engulf them, slowly digesting the struggling victims even as they suffocate inside the ooze.
