When a creature with an  Intelligence  of 4 or higher starts its turn within 30 feet of the chaos raptor, the creature must make a DC 18  Charisma  saving throw. On a failure, the creature can\xe2\x80\x99t take  reactions  until the start of its next turn and must roll a d8 to determine what it does during that turn. On a 1 to 4, the creature does nothing. On a 5 or 6, the creature takes no action but uses all its movement to move in a random direction. On a 7 or 8, the creature makes one  melee attack  against a randomly determined creature within its reach, or it does nothing if no creature is within its reach. At the start of the chaos raptor\xe2\x80\x99s turn, it chooses whether this aura is active. \n'b'  Earth Glide . The chaos raptor can burrow through nonmagical, unworked earth and stone.

It slumbers within mountains, awakening when hungry, at which time it flies to a nearby settlement, driving the residents mad. While the townsfolk scatter, incapable of controlling their random urges, the creature absconds with enough locals to sate its hunger. \n'b'  Born of Stone . While not made of stone, chaos raptors have an affinity for it. They can easily travel through stone and hide inside it, rejuvenating their bodies. Some scholars believe they originate from the Elemental Plane of Earth and arrived on the Material Plane through a massive portal deep within the mountains. \n'b'  Harbinger of Chaos . Chaos raptors cause chaos wherever they go, and indeed, they enjoy disorder. They do not delight in cruelty so much as reckless abandon and disruption. \n'b'  Worshiped and Appeased . It is common for a chaos raptor to nest inside a mountain near a particular town. The locals often worship the chaos raptor as a deity, bringing sacrificial offerings of livestock or even people to appease its hunger. This meets with varying results, for the chaos raptor is temperamental and sometimes attacks even when it is not hungry.'
