Tremorsense (Imprecise) 60 feet

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.

Viviparous Birth

When killed, an empress bore worm violently expels the young it carries. These young erupt as a Bore Worm Swarm in the empress bore worm's space.

In addition, every creature within 20 feet takes 5d10 acid damage (DC 25 basic reflex save) from the splatter of caustic viscera.

Borer

An empress bore worm can leave a tunnel behind itself when it burrows, and it usually does.

Corrosive Wake

The empress bore worm Strides, leaving behind dribbles of acid in every square that it passes through.

A creature that enters or begins its turn in such a square takes 3d6 acid damage (DC 22 basic fortitude save). The acid becomes inert after 1 minute.

Painful Bite

The bite of an empress bore worm causes excruciating pain. The target must succeed at a DC 25 fortitude save or become Sickened 1 from the pain (Sickened 2 on a critical failure).

When an area lacks sufficient food, the bore worms in a swarm become increasingly agitated and desperate. Eventually, at some chemical signal, the worms begin to cannibalize each other, devouring one other in a frenzy too gruesome to behold. A single worm emerges from this melee victorious; it rapidly grows larger and more voracious until it reaches an absolutely elephantine size.

This empress bore worm lives only briefly, as it sets out in search of a new feeding ground and eats everything in its path in an attempt to sustain itself. However, the empress bore worm's ravenous metabolism demands more from its body than what it can physically sustain, as it exists only as a vessel for the next generation. Most live only a few days, or weeks at best, traveling and eating nonstop before dying-and in so doing, giving birth to new swarms of bore worms.

These Darklands vermin produce corrosive, noxious slime and deliver agonizing bites, whether as a revolting, wriggling swarm of finger-length worms or a single massive, lurching beast. Among Darklands communities, most inhabitants regard bore worms much in the same way surface cultures speak of maggots or cockroaches-with general disdain and revulsion. Children consider catching a single bore worm and using it to torment others a rite of passage, albeit a dangerous one.

The humble bore worm is a small and simple creature, both biologically and magically. These qualities allow it to adapt rapidly to different environments, some of them quite extreme, and also makes it susceptible to magical radiation and experimentation. Many a Darklands apprentice takes their first steps in the school of transmutation by practicing on these worms, while variations-both natural and cultivated-are scattered about beneath Golarion's surface.
