SPECIAL TRAITS

  • Legendary Resistance (1/day). If the cauldron bloom fails a saving throw, it can choose to succeed instead.
  • Magic Resistance. The cauldron bloom has advantage on saving throws against spells and other magical effects.
  • Sanguine Centrifuge. A creature that enters or begins their turn within the cauldron bloom’s stomach is blinded and restrained, has total cover against attacks and other effects outside the worm, and takes 18 (2d8 + 9) bludgeoning damage and 10 (3d6) necrotic damage as spinning arcane currents force the blood from their bodies. A creature that begins its turn in the stomach must make a DC 18 Dexterity save; on a failure, the creature is incapacitated until the beginning of its next turn due to these forces. If the cauldron bloom takes 30 damage or more on a single turn from a creature inside it, the cauldron bloom must succeed on a DC 18 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 cauldron bloom. If the cauldron bloom dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement, exiting prone.

ACTIONS

  • Multiattack. The cauldron bloom uses Warping Field. Then it makes a slam attack.
  • Slam. Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 18 (2d8 + 9) bludgeoning damage.
  • Terraforming Teleport (1/day). The cauldron bloom teleports itself and its stomach contents up to 1 mile, to a destination within enough stone, soil, sand, or similar material to surround the cauldron bloom’s body. The material the cauldron bloom will occupy is in turn teleported to backfill the cavity left by the creature’s departure. If a cauldron bloom attempts to teleport to an invalid location, the ability fails with no effect.
  • Warping Field. A cauldron bloom draws prey close with invisible arcane strands. Each creature within 120 feet of the cauldron bloom must make a DC 18 Dexterity save. A creature that fails the save is teleported 60 feet toward the cauldron bloom; if this would bring a creature or object within 30 feet of the cauldron bloom, it is instead teleported into the cauldron bloom’s stomach.

LEGENDARY ACTIONS

The cauldron bloom can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The cauldron bloom regains spent legendary actions at the start of its turn.

  • Detect. The cauldron bloom makes a Wisdom (Perception) check.
  • Invisible Strand (Costs 2 Actions). One creature within 360 feet the cauldron bloom can see must make a DC 18 Constitution saving throw. If the creature fails, it is teleported into the cauldron bloom’s stomach.
  • Slam Attack. The cauldron bloom makes one slam attack.

ABOUT

Cauldron blooms are immense, slow-moving subterranean plants that maintain their arcane metabolisms by consuming massive quantities of blood. They dwell in cold environs, typically along the migration routes of herd animals, and slowly teleport to new locations in search of food. Feeding cauldron blooms generally erupt from the ground in the midst of such herds. The animals’ panicked cries are cut short when the terrified individuals wink out of existence, reappearing a moment later inside the cauldron bloom’s otherworldly guts. Arcane winds within the cauldron bloom’s stomach rapidly draw the blood from ingested prey, shred their bodies, and leave nothing behind. A particularly hungry cauldron bloom can systematically consume entire herds of animals or sequester one individual—such as an unlucky giant or megafauna—inside its stomach. The prey’s blood fuels the plant’s magical physiology, casting flickering arcane light as it distributes throughout the cauldron bloom’s body.

Nexus Digestion. Typically, cauldron blooms live for hundreds of years. Their bodies are around 15 feet in diameter and weigh upward of 80 tons. Cauldron blooms do not feed in a traditional sense. Instead, they wrap potential prey in invisible threads of magical energy.

Snared creatures are teleported directly into the blooms’ stomachs, where interior winds swirl in a roaring arcane centrifuge that forcibly extracts prey’s blood and quickly renders any mundane organic material to a fine powder.

Equipment and magical oddities are left behind, however, meaning clouds of manufactured shrapnel circulate within most older cauldron blooms.
