Painful Bite (Ex)

Living creatures damaged by a bore worm are racked with panic-inducing pain, gaining the frightened condition (Fortitude DC 15 negates) for 1d6 rounds. The save DC is Constitution-based.

Vulnerable to Water (Ex)

Water is lethal to bore worms, which shrivel when exposed to either fresh or salt water.

Bore worms take half again as much damage (+50%) from spells and abilities with the water descriptor, and take a –2 penalty on saving throws against spells and abilities with the water descriptor that do not deal hit point damage.

Bore worms are a vile breed of subterranean burrowing worm, attacking prey both in their home and, more rarely, on the planet’s surface. Three major variants of the worms exist, each representing a different stage in the creature’s long life cycle—the swarm, monarch, and empress stages.
