These mutants are a far deadlier version of the mutants known as the feral Undying. These creatures share many of the same traits, and were created in the same manner as the other versions. The difference between these creatures and the other Undying is that they are typically deadly to any other creatures to even be near them.

These mutants are a far deadlier version of the mutants known as the feral Undying. These creatures share many of the same traits, and were created in the same manner as the other versions. The difference between these creatures and the other Undying is that they are typically deadly to any other creatures to even be near them.

They constantly radiate a powerful field of deadly radiation at a range of 5’ from their bodies. This radiation is so powerful that it kills most creatures that encounter it, and cause flammable materials to burst into flame. Any item coming within the radiation field emitted by the creature must save versus energy (using the victim’s saving throw) or save versus thermal (if the Mutant Lord is using the saving throw tables included in Wisdom from the Wastelands issue 1). The heat is so intense that it also does 3d6 points of damage per round to anyone who is in close physical proximity to the creature.

Due to the radiation and thermal emissions of the creature, attacking them with melee weapons or any sort of physical attack or natural weapon is a very dangerous proposition at the best of times.  The best way to deal with these monsters is from a distance.

Unfortunately these creatures are as mindless as the feral Undying creatures, their minds having been long since destroyed by the radiation that keeps them alive –if you could call this state of existence living.

Physically these mutants appear to be feral Undying with one major exception. The feral creatures do not possess the same powerful greenish glow that these monsters possess. That in of itself should be an indication of just how dangerous these creatures can be. This hellish glow can be clearly seen for miles in any direction and provide the same illumination as a torch would. What makes it even more unsettling is that the bones and circulatory system is clearly visible.

It has been discovered that these creatures cannot survive without hard radiation for very long. As a result, they are typically found only in locations where there is a source of high intensity radiation. They are most commonly found in or near the ground zero inside ruined cities or other locations that had been targeted by conventional nuclear weapons during the Ancient’s final wars.  

When they are forced to move away from intense radiation, these creatures will suffer 2d12 hit-points of damage for every 12 hours they cannot bathe in the glowing energies. Even class 1 radiation will sustain them but they prefer the more intense radiation zones.

In fact, these mutants can’t heal any damage they sustain without radiation. Instead of having a healing rate, these mutants will restore 1 hit point per level of radiation that they are exposed to every 24 hours.

Also, these creatures are able to store hard radiation in their bodies, which they can release as powerful bursts. This costs the creatures hit points and they suffer 3d6 points of damage each time they use the attack. The bursts are radiation class 10 (which is deadly in on its own) and on top of that they cause 6d6 heat damage to anything within 30’ of the creature.

When the Glowers engage in combat they like to close and engage any targets they can find. Like the feral Undying, they attempt to bite and eat their targets, despite the fact that they gain no nutritional value from the consumption of flesh.

Unlike the feral Undying, victim’s exposed to the toxins that these mutants carry will not have to worry about the possibility of being transformed into one of these creatures. Scholars theorized that because of this, the population of these horrific mutants would diminish over time. Sadly, that isn’t the case. It is speculated that these creatures cannot be killed unless they are physically removed from a radiation zone. Even if reduced to below zero hit points it is speculated that the monsters are regenerated by the radiation over time.

Another reason that the population has not diminished is because they are still coming into existence as a result of pure humans, humans (see Wisdom from the Wastelands issue 4) or mutant humans being exposed to the toxins and the high levels of hard radiation that is found commonly in the ruins of the Ancients.

Sometimes these mutants are found with the feral Undying and they will use their radiation burst to heal their brethren.  This sudden burst of intense radiation will instantly heal any undying for 10 hit points.

Mutations: Bizarre appearance(d), extended life span, immunity to radiation and all toxins, toxic weapon (radiation burst).
