Gray Worm

Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

The gray worm can smell blood in the air from up to 1 mile away, or in the earth from up to 1,000 feet away.

The gray 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.

Frequency once per day Trigger The gray worm would be affected by a condition or adverse effect (such as Cursed Metamorphosis) Effect The gray worm negates the triggering condition or effect. Effects from artifacts, deities, or a similarly powerful source can't be avoided in this way.

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Any living creature hit by a gray worm's stinger Strike must succeed at a DC 27 fortitude save or become Paralyzed. It can attempt a new save at the end of each of its turns, and the DC cumulatively decreases by 1 on each such save.

The worm makes a Strike once against each creature in its reach. It can Strike up to once with its jaws 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.
