The sandwyrm makes one Bite  attack , one Gore attack, and one Stinger attack. \n'b'  Bite .  Melee Weapon Attack : +8 to hit, reach 5 ft., one creature.  Hit : 12 (2d6 + 5) piercing damage. \n'b'  Gore .  Melee Weapon Attack : +8 to hit, reach 10 ft., one target.  Hit : 11 (1d12 + 5) piercing damage. \n'b'  Stinger .  Melee Weapon Attack : +8 to hit, reach 10 ft., one creature.  Hit : 9 (1d4 + 5) piercing damage, and the target must make a DC 15  Constitution  saving throw, taking 14 (4d6) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0  hp , the target is stable but  poisoned  for 1 hour, even after regaining  hp , and is  paralyzed  while  poisoned  in this way. \n'b'\n'b' REACTIONS \n'b'\n'b'  Spine Trap . When the sandwyrm is burrowed just below the surface of sand with its back spines exposed and a Medium or smaller creature enters the spines\xe2\x80\x99 space, the sandwyrm closes the spines on the creature. The creature must succeed on a DC 15  Dexterity  saving throw or be  restrained . When the sandwyrm moves, a restrained creature moves with it. The sandwyrm can have only one creature restrained at a time. A creature, including the restrained creature, can take an action to free the restrained creature by succeeding on a DC 15 Strength check. \n'b'\n'b' ABOUT \n'b' The large, bleached bones protruding from the desert sand suddenly shift and reveal themselves to be the boney spikes of a great reptile. \n'b'  Hidden by Sand . These lethargic, horned, yellow-scaled lizards spend most of their lives underground, lying in wait under the desert sand with their long-necked, spine-tailed bulk hidden below the surface. Only the long, jagged bones lining their backs are exposed. These bones resemble a sun-bleached ribcage so perfectly that it attracts carrion birds\xe2\x80\x94and curious travelers. When prey passes between the \xe2\x80\x9cribs,\xe2\x80\x9d the sandwyrm snaps the rows of bone tightly over its prey. Once its victim is restrained, the sandwyrm paralyzes its meal with repeated stings before carrying it away. \n'b'  Torpid and Slow . Sandwyrms sometimes wait for weeks in torpid hibernation before footsteps on the sand alert it to a fresh meal approaching. To guard against lean weeks, sandwyrms store excess prey in subterranean lairs. They\xe2\x80\x99re not above eating carrion if fresh meat isn\xe2\x80\x99t available. When outmatched in a fight, sandwyrms retreat to their lairs with their paralyzed prey. \n'b'  Peculiar Drakes . Sandwyrms evolved as an offshoot to drakes or wyverns rather than from true dragons; their anatomy suggests they were originally four-limbed creatures and that their forearms are recent additions to the animal\xe2\x80\x99s body. The bones on their backs may have once been wings, suggesting that sandwyrms are the remnants of some primordial, winged reptiles that migrated to the deep deserts.'
