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).
Empress Bore Worm
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.
