Glassmaw Burrower, Mother-of-Teeth - AI-generated fantasy Monster

Glassmaw Burrower, Mother-of-Teeth

Vask, Shardjaw, the Salt Widow, and Mother-of-Teeth are names used by different wasteland communities for the same species. Scavengers disagree about whether the creature's chimes predict storms, magic surges, or death. All three claims are sometimes true. The Order of the Source has hunted several Glassmaw Burrowers because they can detect Source pulses through salt and stone. Their discarded equipment suggests the cult once tried to train them, but the torn harnesses and punctured cages indicate that no alliance survived contact with a hungry parent.

Vibration Hunter. The burrower has advantage on Wisdom (Perception) checks that rely on hearing or vibration. While touching the ground, it knows the location of every other creature touching the same ground within 120 feet, even through solid material. This sense does not reveal creatures that are motionless and isolated from the ground.
Saltglass Burrower. The burrower can move through saltglass, sand, and packed earth without squeezing. It leaves behind unstable cavities. The first time each round that a creature other than the burrower enters a space above one of its burrows, that creature must succeed on a Dexterity saving throw or fall prone and become restrained until it escapes with a Strength (Athletics) or Dexterity (Acrobatics) check.
Mineral Resonance. The burrower has advantage on saving throws against spells and other magical effects that would charm, frighten, or control it. It has disadvantage on saving throws against thunder damage while its chimeback nodules are exposed, such as after it uses Resonant Chime.
Chimeback Pulse. The burrower has three charges of Resonant Chime. It regains one expended charge whenever it takes thunder damage and regains all expended charges after finishing a long rest. If it has no charges, it cannot use Resonant Chime.
Territorial Warning. The burrower does not attack creatures that remain at least 80 feet from the nesting shelf, make no attempt to approach its eggs, and create no sharp vibration. If confronted at that distance, it clicks, displays its mouth, and waits. A creature that succeeds on a Wisdom (Animal Handling) or Intelligence (Nature) check can recognize this as a warning rather than an attack.
Mother-of-Teeth. When reduced to 63 hit points or fewer, the burrower gains advantage on attack rolls made against creatures within 10 feet of an egg. It also gains resistance to all damage except psychic damage while it is directly covering at least one egg.
Multiattack. The burrower makes one Bite attack and one Claw attack, or uses Saltglass Surge if available.
Bite. Melee Weapon Attack: to hit, reach 10 ft., one target. Hit: 27 () piercing damage. If the target is Huge or smaller, it is grappled, escape . Until this grapple ends, the target is restrained, and the burrower cannot use its Bite against another target.
Claw. Melee Weapon Attack: to hit, reach 15 ft., one target. Hit: 16 () slashing damage. If the target is Large or smaller, it must succeed on a Strength saving throw or be knocked prone.
Saltglass Surge. The burrower erupts from a point on the ground it can sense within 60 feet. Each creature within 15 feet of that point must make a Dexterity saving throw, taking 22 () bludgeoning damage and falling prone on a failed save, or half as much damage on a successful one. The area becomes difficult terrain until cleared. The burrower can then move up to half its burrowing speed without provoking opportunity attacks.
Resonant Chime. The burrower releases a pulse through its mineral growths. Each creature of the burrower's choice within 30 feet that can hear the chime must make a Constitution saving throw. On a failed save, a creature takes 18 () thunder damage and is deafened until the end of its next turn. On a successful save, it takes half damage and is not deafened. A creature concentrating on a spell has disadvantage on the saving throw to maintain concentration caused by this damage.
Whisker Snare. The burrower lashes out with sensory whiskers at a creature within 20 feet. The target must succeed on a Dexterity saving throw or be pulled up to 15 feet toward the burrower and blinded until the end of its next turn. A creature wearing or carrying a loud machine component has disadvantage on this saving throw.
Guard the Clutch. When a creature the burrower can sense moves within 15 feet of an egg or damages the nesting shelf, the burrower makes one Claw attack against that creature, if the creature is within reach. On a hit, the attack deals an extra 7 () slashing damage.
Burrowing Advance. The burrower moves up to half its speed without provoking opportunity attacks. It can burrow during this movement.
Raking Claw. The burrower makes one Claw attack.
Reverberating Lunge (Costs 2 Actions). The burrower uses Whisker Snare or moves up to its burrowing speed without provoking opportunity attacks.
Basin-Shaking Chime (Costs 3 Actions). The burrower uses Resonant Chime, if available, or uses Saltglass Surge if available.
