Inexorable The purple worm recovers from the paralyzed, slowed, and stunned conditions at the end of its turn. It's also immune to penalties to its Speeds and the immobilized condition, and it ignores difficult terrain and greater difficult terrain.
Shake It Off Frequency once per day; Trigger The purple worm would be affected by a condition or adverse effect (such as baleful polymorph). Effect The purple worm negates the triggering condition or effect. Effects from artifacts, deities, or a similarly powerful source can't be avoided in this way.

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 deals 2d6+13, Small 3d6+13, Medium 4d6+13, Large 5d6+13, and Huge 6d6+13. 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 stomach as a creature of equivalent size, and purple worms often have several boulders swallowed. A purple worm can use a single action to swallow a new boulder.
Rock Tunneler A purple 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.
The purple worm is the most common and infamous of the cave worms, a much-feared monster wandering the twisting tunnels that is capable of carving out entire cave systems. Tunnels bored by a purple 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.
