Fast Swallow

Trigger The cave worm Grabs a creature.


Effect The worm uses Swallow Whole.

Regurgitate

The purple worm can violently regurgitate a creature or boulder it has swallowed to make a ranged Strike. The Strike deals bludgeoning damage depending on the size of the projectile:

  • Tiny (2d6+13)[bludgeoning]
  • Small (3d6+13)[bludgeoning]
  • Medium (4d6+13)[bludgeoning]
  • Large (5d6+13)[bludgeoning]
  • Huge (6d6+13)[bludgeoning]

A regurgitated creature takes falling damage from the height of the target or from 20 feet, whichever is greater.

Boulders occupy space in the worm's stoma

Rock Tunneler

A cave worm can burrow through solid stone at a Speed of 20 feet. It can leave a tunnel if it desires, and it usually does.

Swallow Whole

Huge, (3d6+9)[bludgeoning], Rupture 24


Thrash◆◆

The worm makes a Strike once against each creature in its reach. It can Strike up to once with its jaws, up to once with its stinger, and any number of times with its body. Each attack counts toward the worm's multiple attack penalty, but the multiple attack penalty doesn't increase until after it makes all the attacks.

Improved Grab

The most common and infamous of the cave worms gives its name to the entire family—a much-feared monster wandering the twisting tunnels of the Darklands that is capable of carving out entire cave systems. Tunnels bored by a cave worm don't always last long after these creature's passage, and areas where they nest are maddening mazes of passageways that lead nowhere, yet navigating the labyrinth to find the worm's central nest often yields amazing treasures left behind by the worm's prior victims.


Cave worms are gigantic scavengers that bore through the depths of the world, eating whatever material they find. Named for their distinctive habitats, these worms are ravenous and display overwhelming destructive capabilities. Cave worms of different types and abilities lurk in the more remote corners of the world—tales speak of arctic worms that dwell within immense glaciers or icebergs and grave worms that burrow through the boneyards of long-forgotten ruins, to name a few.
