I hope you like this giant worm, and I'll be back next Friday with a new monster. Thanks for reading!
This massive brown worm has a considerable array of stinging bristles along its body. It also has an unusually powerful set of jaws for a worm.

Many Stingers (Ex) While a polychaete terror can only bring 12 of its bristly stingers to bear in an attack, if it successfully uses its Improved Impaling Critical it does not lose any sting attacks while maintaining any impalements.
Polychaete Numbing Poison (Ex) String—injury; save Fort DC 29; frequency 1/round 6 rounds; effect 2d4 Dex (2 points of which are Dex drain); cure 2 consecutive saves. The save DC is Constitution-based.
Powerful Lunge (Ex) A polychaete terror can rapidly stretch its body out, giving it a 60-ft. reach until the beginning of its next turn. This imposes a -4 penalty to its AC. Due to the suddenness of this lunge, a character must succeed at a DC 20 Perception check to avoid being flatfooted against the polychaete.
Another baleful creation of the dread kraken, a polychaete terror is a giant sea worm grown to extraordinary size and gifted with a number of defensive capabilities. The creature's countless paralytic bristles are augmented so its poison has incredible potency. Finally, the segmented creature has a near rubbery quality, allowing it to instantly expand itself to make surprising attacks against its foes. A polychaete terror measures 35 feet in length and weighs 3 tons.
A dread kraken typically unleashes the mindless creature on a major population center, where the creature's incredible appetite drives it to a frenzy of destruction. After it causes some carnage, it fights until nothing else attacks it, at which point it stops and feasts on the victims it has impaled on its bristles. Usually left unsatisfied with that meal, it hunts for more prey. Characters who dispatch a polychaete terror are reward not only with whatever treasure survives in the creature's gullet, but also with easily obtained poison (requiring a DC 10 Heal check for one dose + one dose per 5 points over 15). A dose of polychaete terror poison has a price of 7,000 gp.
Variant Polychaete Terrors
Dread krakens did not stop with the base polychaete terror, especially since the creature's annelid nature renders it magically manipulable. A GM can apply the following changes to a polychaete terror to create a variety of encounters (or multiple different polychaete terrors in a single encounter).
Acidic Bristles This version of the polychaete replaces its sting's poison for an additional 1d6 acid damage when it hits with a sting. If it successfully impales a foe with a bristle, it deals this acid damage each round the foe remains impaled.
Breath Weapon This variant polychaete can breathe its digestive fluids in a 60-ft. line that deals 6d6 acid damage to each target in the line (DC 29 Reflex save for half). The save DC is Constitution-based. The polychaete requires 1d6 rounds between uses of its breath weapon.
Flight One fourth of the polychaete's bristles have the ability to levitate the creature. This allows the polychaete to crawl through the air, giving it a fly speed of 40 feet (clumsy).
Split Replace the polychaete's DR with this ability. Slashing and piercing weapons deal no damage, but the polychaete instead divides into two identical versions with half the original's current hit points. A polychaete with 20 or fewer hit points can no longer split.
