Inexorable The cave 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.

Slough Skin ⟲ Frequency once per day

Trigger The cave worm would be affected by a condition or adverse effect (such as Cursed Metamorphosis)

Effect The cave worm negates the triggering condition or effect by sloughing an outer layer of its skin. Effects from artifacts, deities, or a similarly powerful source can't be avoided in this way.

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

• Small 3d6+13

• Medium 4d6+13

• Large 5d6+13

• 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 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 ◆ (attack) 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.
