Physical Description

A sewer zombie appears as a seven foot tall humanoid creature. It has smooth, green skin with a segmented spider web pattern of what looks like green veins. The head has no visible eyes, nose or mouth. The entire creature is coated in a thick, yellow-green slime. Sewer zombies exude a very powerful stench. But their environment often masks this foul odor.


They absorb nutrients, food, etc. with a chemical reaction through their skin. This gives them acidic flesh/touch. They attack by touching prey and dissolving/absorbing nutrients. This can even dissolve metal and stone, but gain no nutrition that way. When attacking, the victim's armor will not help them. Zombies simply mindlessly attack the form in front of them. They will partially dissolve and weaken armor on every strike.

Because sewer zombies are mindless and aggressive, they are unaffected by charm magic or other mind-affecting spells.

Sewer zombies have excellent thermal vision. Probably for this reason, they dislike bright lights and large heat sources. Sewer zombies never venture out into daylight.

Once a zombie scores a hit, they grab hold and attempt to grapple the victim.  Remember, if the victim tries to grab the zombies hand and pry it off, their gloves will dissolve and they will burn their hands. If they try anyway, it’s a contest of strength. Sewer zombies are surprisingly strong. Once the zombie has grabbed hold of a victim, the zombie will continue to do damage, dissolving through armor, clothing and into flesh.

Sewer zombies are rampant with disease and each time they touch a victim's flesh, there is a chance that the victim will contract a disease.

Each time a character attacks a sewer zombie with their weapon and hits, the weapon is affected by the acid and weakened. Each weakening results in a 10% reduction in damage. cumulative chance of the weapon breaking or otherwise being destroyed. Likewise, each successful attack made by a sewer zombie against armor gradually eats the armor away.

Sewer zombies have no bones, only extensive cartilage and rubbery flesh. They have no blood or circulatory system at all. All internal systems are decentralized. No internal organs. Therefore precise attacks against specific internal organs (such as attempting to stab the heart) will not work against them. Their tough, rubbery flesh makes them extremely damage resistant. Cuts seem to seal up quickly and bludgeoning weapons seem to bounce off with little effect.

Because they have no respiratory system and breathe through their skin, they can’t drown and can stay submerged indefinitely.

Because these are creatures of filth, all forms of purification damage them. Healing magic and spells the purify in some way can be used to damage these things.

While in contact with their native environment (stagnant and polluted water), sewer zombies regenerate at a slow, but constant rate. Fire is only partially effective against them due to their slime coating.

Because of the creatures' feeding habits and diet, they are completely immune to disease, toxins and poisons of all sorts.

Geographic Distribution and Habitat

These disgusting creatures feed by absorbing filth, garbage and stagnant, polluted water. It is understandable, then, why they thrive in sewers. Sewer zombies can also be found in marshes and, occasionally, in rivers. But they seem to prefer the sewers of large cities.


No one knows where the first sewer zombies come from. Perhaps the creation of a wizard, a biological weapon from the Great War or maybe they are an aberrant spawn of Nature. In any case, little is known of these creatures, their life cycles or their biology. No one has taken the time to study them. They seem to have spread and can be found anywhere that has filth, garbage, stagnant water and such. They will always be found in places where they are protected from daylight (such as underground or in the heart of deep swamps).
