SPECIAL TRAITS

• Acidic Bite. If a bloodsucking wyrm misses on an attack, but would strike on a touch attack, it latches on to an otherwise armored part of a character and begins to secrete acid which dissolves the armor. On the next round the wyrm breaks through and begins to deal bloodsucking damage to the mouth and no face of which to speak. Its brow is flat, with a broad flat scale covering the brain pan. The mouth is filled with broad triangular teeth that run the length of the top and lower jaw. The scaj are made of thousands of scales, and have no guts, blood or any other earthly component. When struck only dust follows the arc of a blade, or rises from the shattered blow of a hammer.

ABOUT

The larger cousin of the blood worm, bloodsucking wyrms are medium-sized, snake-like wyrms generated from the filth, corruption and blood of evil dragons. As the corruption and filth of these dragons’ bodily secretions falls upon mud and muck, the worms spawn from the mystical corruption generated. Once a single one is born, it quickly propagates, spreading over swamps and morass until it becomes a small army of deadly parasites.

They cough constantly, hacking up ash and clouds of dust. The hacking seems a warning, but as with their other actions, it possesses no purpose.

These wyrms lie in wait within swamps and muck, mindlessly waiting and driven by instinct to feed whenever the opportunity presents itself.

They are long and thick, and can grow from several feet up to 12 feet long or more-easily the size of a python. They are black, squamous, scaly creatures, reptilian in nature, and possessed of a leech-like mouth lined with thousands of tiny teeth. They look a bit like a cross between a black python and a lamprey.

Mindless Parasites. Bloodsucking wyrms are instinct-driven parasites, largely mindless and waiting for victims to pass by.

As soon as a potential meal passes within range, the parasite lashes out, latching on with impossible strength and draining the victim of blood. They are able to secrete an acid from their mouth which will eat through armor, clothing and other forms of protection, damaging the armor in the process of attacking.

Metabolic Reproduction. Bloodsucking wyrms reproduce from the act of feeding. The more they feed, the more larvae they produce. A single victim drained to death is enough to produce several dozen larvae; as such, these creatures can grow to plague-levels very quickly. Larvae mature within 1d4 weeks to full size, though as many as 50% of the larvae may be consumed and re-absorbed by the parents to sustain their ongoing metabolism. Larvae consumed in this manner do not result in additional spawn.
