Ambush (Ex) The Contaminator is perfectly aware of the environment it inhabits, and as such it is able to use it to its advantage when hunting live prey to destroy. The creature gains a +4 racial bonus to Stealth as a result.
Create Spawn (Su) The toxic gas produced by the Contaminator will turn any corpse within the area of effect (see below), into a Slicer Xeno-necro in 1d4 rounds.
Death Detonation (Su) Upon its death, the Contaminator will explode. This will cause 3d6 acid damage, in a 15 foot radius and a Ref save (DC 15) for half damage. Furthermore, anyone caught in the area of effect will suffer 1d2 points of acid damage per round for 1d4 rounds after the creature detonates. Furthermore, the Penetrating Poison Gas is likewise released upon its death (see below), unless it has already used up its allotment of discharges for the day.
Energy Vulnerability (Ex) The Contaminator, like all Xeno-necro’s, are particularly susceptible to energy attacks, such as lasers, plasma weapons, and other similar weapons. They suffer an additional +1 point of damage per dice when facing this type of attack.
Penetrating Poison Gas (Su) As a full round action, the Contaminator is able to generate a cloud of noxious gas. This gas is able to get into even the most tightly enclosed suits, and will even work in the vacuum of space. Anyone struck by the gas must make a Fort save (DC 15) or suffer 1d4 points of temporary Constitution damage, and will become nauseated for 1d6 rounds. This gas attack will only affect living creatures. The gas covers an area of 30 feet, centered on the Contaminator. It can use this ability four times per day.
A specialized form of Xeno-necro, this particular creature serves a function very similar to that of the Desecrator. Its purpose is to contaminate the atmosphere with the same toxin which can not only kill living creatures, but cause them to rise as Slicers.
The Contaminator is created using a single medium-sized humanoid corpse. Anything the corpse was wearing is destroyed in the transformation. The hair falls out and the body turns a pale grey. The face and head remain relatively unchanged, except the mouth is open in a permanent look of surprise, from which a greenish vapor is constantly flowing. The back has become grotesquely engorged, and once the creature is killed, it explodes, filling the area with the toxin.
They are somewhat slow-moving, and always travel in packs of Slicers for protection, often staying in the aftermath of a battle to infect and change the corpses created by the slicers into new slicers.
Those who have encountered the Contaminators – and lived to speak about it – tell tales on how the gas they produce will penetrate even the best vacuum suits and armor, and the only way to avoid the effects is to stay out of the area of effect. They also warn to make sure to stay well clear of the creatures, as when they are finally destroyed, they will explode, potentially inflicting terrible casualties with the final act of defiance.
