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

Abilities

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 mage-eater worm violently expels the young it carries. These young erupt as a Mage-Eater Worm Swarm in the empress bore worm's space.

In addition, every creature within 20-foot emanation{20 feet} takes 5d10 acid damage (DC 25 Reflex save) from the splatter of caustic viscera.
Borer — An empress mage-eater worm can leave a tunnel behind itself when it burrows, and it usually does.
Corrosive Wake — The empress mage-eater 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 Fortitude save). The acid becomes inert after 1 minute.
Painful Bite — The bite of an empress mage-eater 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).

Additionally, the worm also attempts a counteract check against a single spell affecting the creature (counteract rank 3, counteract modifier +12).

WORKS WELL WITH

AnvilLAND / SUBTERRANEANA durable frontline body can absorb the worm's reach bite so squishier allies stay clear of both the mouth and the acid trail.
SniperLAND / SUBTERRANEANA ranged attacker can whittle down the worm from outside its generous reach and avoid the corrosive terrain it leaves behind.
WeaverLAND / SUBTERRANEANA caster applying persistent damage or debuffs stacks well against a foe already vulnerable to sustained pressure rather than single burst hits.

PUNISHES

✖ clumping✖ melee reliance✖ standing still
Its death triggers a reinforcement brood, so pairing with another creature that adds reinforcements on defeat can chain encounters beyond what the party expected.
