Special Traits

  • 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 attacks with its pseudopod.
  • Pseudopod. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage. If the target is Medium or smaller, it is grappled (escape DC 15) and restrained until the grapple ends. The livestone can grapple two targets.
  • 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 AC 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. A livestone must use an action to desolidify itself.


A large slab of moss-covered rock seems to ooze and move before you.

Livestone is a strange species of ooze that can solidify itself into a consistency that very closely resembles that of stone. In its solidified form, a livestone is indistinguishable from a normal boulder or slab of rock. No one is quite sure from where livestones originated, but ancient legends say that the dwarves accidentally unleashed these horrors on the surface world by digging into their subterranean lairs. Eventually, some livestones found their way to the surface. Livestones are incredibly long lived, solidifying and entering a form of hibernation and remaining that way indefinitely until a food source wanders too near. Livestones have a simple chameleon-like ability to mimic local stone by ingesting a small sample and adjusting its own color and texture to match. A hibernating livestone can become covered in moss and lichens to further the deception.

Livestones generally attack from ambush, waiting for a potential meal to pass before flowing into their ooze form and rushing up to engulf the prey. If the surprise attack fails, a livestone resorts to hammering with a hard-as-rock pseudopod.
