SPECIAL TRAITS

  • False Appearance. While the stone creeper remains motionless, it is indistinguishable from an ordinary vine.
  • Mass of Vines. The stone creeper can move through a space as narrow as 1 foot wide without squeezing.
  • Spider Climb. The stone creeper can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

ACTIONS

  • Thorned Vine. Melee Weapon Attack: +4 to hit, reach 10 ft., one creature. Hit: 5 (1d6 + 2) piercing damage plus 5 (2d4) acid damage.
  • Acid-coated Thorn. Ranged Weapon Attack: +4 to hit, range 20/60 ft., one creature. Hit: 4 (1d4 + 2) piercing damage plus 2 (1d4) acid damage.
  • Weaken Stone. While climbing on a wall or ceiling made of worked stone, the stone creeper injects its acid into the mortar, weakening the structure. Each creature within 10 feet of the wall or in a 10-foot cube beneath the ceiling must make a DC 12 Dexterity saving throw, taking 7 (2d6) bludgeoning damage on a failed save, or half as much damage on a successful one. A creature that fails its saving throw when beneath a ceiling is also knocked prone and buried. The buried target is restrained and unable to breathe or stand up. A creature, including the target, can take its action to remove the rubble and free the buried target by succeeding on a DC 10 Strength check.

ABOUT

This plant looks like a cluster of vines with elongated tendrils and leaves. A clear fluid drips from its thorns and spatters on the floor around it.

Feed on Stone. Stone creepers are semi-intelligent plants that feed on the mortar that holds structures together. They are commonly found in abandoned castles, ruins, and underground locations where the tunnels and chambers were reinforced with stone or brick. The stone creepers secrete acid into the mortar holding the building materials together, breaking it down quickly for easy consumption.

Living Traps. Stone creepers are typically found deeply enmeshed within stone or bricks and hidden in walls. Most creatures that initially see them assume they are ordinary vines. If there is a threat below them, they hastily withdraw from their position, dislodging the bricks or rocks that fall down upon the intruders.

Semi-Social. Stone creepers tend to live in groups of three to five. Often, they nearly encompass an entire room and feed upon it, waiting for hapless victims to enter a room. After they have consumed all the mortar and caused a collapse, they move on to new areas where they begin the process again.
