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\xe2\x80\x99s 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. \n'b'  Regeneration . The stone eater regains 10  hit points  at the start of its turn if it has at least 1 hit point. \n'b'  Seige Monster . The stone eater deals double damage to objects and structures. \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The stone eater makes two attacks: one with its bite, and one with its claws. \n'b'  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\xe2\x80\x99s 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 . \n'b'  Claws .  Melee Weapon Attack : +15 to hit, reach 30 ft., one target.  Hit : 21 (2d10 + 10) piercing damage. \n'b'  Barrage (Recharge 5-6) . The Stone Eater releases a swarm of rock in a 30-foot-radius spread.
