SPECIAL TRAITS

  • Ground Manipulation. The Stone Eater can use an action to cause stone and earth within its space to grow soft and muddy in a radius of 100 ft, centerd on itself. The ground remains muddy for 1 minute after the Stone Eater moves off from the location. The Stone Eater can move through these areas with ease, but other creatures treat them as difficult terrain. If the Stone Eater has buried itself and uses the ability, the muddy ground forms a slippery funnel to its mouth. This muddy funnel requires a DC 18 Dexterity saving throw to avoid sliding to its center where the creature’s mouth awaits. Any creature sliding to its mouth is immediately subjected to a free bite attack and a swallow whole attack. Attempts to climb out of the slippery funnel require a DC 16 Strength (Athletics) check.
  • Regeneration. The stone eater regains 10 hit points at the start of its turn if it has at least 1 hit point.
  • Seige Monster. The stone eater deals double damage to objects and structures.

ACTIONS

  • Multiattack. The stone eater makes two attacks: one with its bite, and one with its claws.
  • Bite. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 19 (2d8 + 10) piercing damage. If the target is a Huge or smaller creature, it must succeed on a DC 19 Strength saving throw or be swallowed by the stone eater. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the stone eater, and it takes 17 (5d6) acid damage at the start of each of the stone eater’s turns. If the stone eater takes 20 damage or more on a single turn from a creature inside it, the stone eater must succeed on a DC 19 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the stone eater. If stone eater dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 10 feet of movement, exiting prone.
  • Claws. Melee Weapon Attack: +15 to hit, reach 30 ft., one target. Hit: 21 (2d10 + 10) piercing damage.
  • Barrage (Recharge 5-6). The Stone Eater releases a swarm of rock in a 30-foot-radius spread. Those within the area of effect must make a DC 18 Dexterity saving throw, taking 45 (10d8) bludgeoning damage on a failure, or half as much on a success.

LEGENDARY ACTIONS

The stone eater can take 2 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The stone eater regains spent legendary actions at the start of its turn.

  • Claws. The stone eater makes one attack with its claws.
  • Burrow. The stone eater moves at its full burrow speed and does not provoke oppourtunity attacks.
