Special Traits

  • Spine Trap. When underground with its spines exposed, the sandwyrm can snap its spines closed on one Large, two Medium, or four Small or Tiny creatures above it. Each creature must make a successful DC 15 Dexterity saving throw or be restrained. A restrained creature can use its action to make a DC 15 Strength check to free itself or another restrained creature, ending the effect on a success. Creatures restrained by this trait move with the sandwyrm. The sandwyrm’s stinger attack has advantage against creatures restrained by this trait.

Actions

  • Multiattack. The sandwyrm makes one bite attack and one stinger attack. It can gore in place of the bite attack.
  • Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 12 (2d6 + 5) piercing damage.
  • Gore. Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 11 (1d12 + 5) piercing damage.
  • Stinger. Melee Weapon Attack: +8 to hit, reach 10 ft., one creature. Hit: 12 (2d6 + 5) piercing damage plus 24 (7d6) poison damage, or half as much poison damage with a successful DC 15 Constitution saving throw. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned and paralyzed for 1 hour. Regaining hit points doesn’t end the poisoning or paralysis.
  • Season’s Change. If a sap demon (or its host) takes at least 10 fire damage, it also gains the effect of a haste spell until the end of its next turn. If it takes at least 10 cold damage, it gains the effect of a slow spell until the end of its next turn.

Actions

  • Multiattack. The sap demon makes two slam attacks.
  • Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 11 (2d8 + 2) bludgeoning damage. If both attacks hit a Medium or smaller target, the target is grappled (escape DC 12), and the sap demon uses Soul Sap on it as a bonus action.
  • Soul Sap. The sap demon slides down the throat of a sleeping, helpless, or grappled living creature of Medium size or smaller. Once inside, the sap demon takes control of its host, as per the dominate monster spell (Wisdom DC 12 negates). While dominated, the host gains blindsight 90 feet. The host drips blood from its ears, nose, eyes, or from a wound that resembles the injury done to the sap demon’s tree (1 damage/ hour). Damage inflicted on the host has no effect on the sap demon. If the host dies or is reduced to 0 hit points, the sap demon must leave the body within one hour.

Appearance

While they mimic the bleached bones of a desert creature, the bony adornments atop along their backs are part of their peculiar melding of bone and scale.

About

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 and only the long, jagged bones lining their backs exposed. These bones resemble a sun-bleached ribcage so perfectly that it attracts carrion birds-and curious travelers. When prey passes between the “ribs,” 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.

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’re not above eating carrion if fresh meat isn’t available. When outmatched in a fight, sandwyrms retreat to their lairs with their paralyzed prey.

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’s body. The bones on their backs may have once been wings, so that sandwyrms are the remnants of some primordial, winged reptiles that migrated to the deep deserts.
