Bright red and coated in an opaque yellow slime, this monstrous worm has a menacing pair of barbed mandibles.
Bore Worm Monarch CR 7
Corrosive Wake (Ex)
When a bore worm monarch burrows, it can move through solid material, including stone and metal, as easily as a fish swims through water. It leaves behind a 5-foot-diameter, smooth-sided tunnel coated in acid that deals 1d3 points of acid damage to creatures coming into contact with its surface. This acid lasts a number of rounds equal to the hardness of material it burrowed through.
Environment any underground
Organization solitary, pair, or tremor (1 plus 1d6 bore worm swarms)
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.
