A cerberus worm is rarely encountered unless it wishes to be. As a full-round action while in water, a cerberus worm can move up to its run speed (300 feet) without leaving any sign of its passing, as though affected by a pass without trace spell. An elusive cerberus worm gains a +40 circumstance bonus on its Stealth check. In addition, except when in combat, a cerberus worm is considered to be under the effects of a nondetection spell.
Both of these spell effects function at caster level 20th and cannot be dispelled.
Once per day, as a standard action that does not provoke attacks of opportunity, a cerberus worm can wreathe itself in a poisonous mist that resembles black, licking flames for 3 minutes. This poisonous cloud surrounds the cerberus worm in a 30-foot radius, and creatures inside the radius are exposed to the cerberus worm’s poison. A creature that successfully saves against the poison once need not attempt additional saving throws while it remains in the poison. If a creature leaves the wreath and reenters it, however, the creature is again exposed to the poison and must attempt another saving throw.
Environment any oceans
Believed to be the only beast of its kind, the cerberus worm is known for smashing them and eating ship crew members alive.
Because of the cerberus worm’s flame-like poison wreath, and because all reports of sightings have occurred in the past few decades, most believe the creature is some sort of infernal monstrosity.
A cerberus worm is approximately 45 feet long and weighs 3,200 pounds.
