Special Abilities
Glow (Ex): Because of the radiation emanating from the creature. This produces dim illumination for up to 30 feet around the creature. It also causes the creature to suffer a -4 to its stealth roll, although this does not matter when the creature is moving through solid matter.
Phase (Su): As a standard action, the Phase rat is able to become insubstantial and it can move into the surrounding terrain. It can move through any type of material, even metal, although it cannot use this ability to pass through energy fields. It is fully able to move while hidden, and cannot be detected (except through vibration sense, or life-sense). The creature will eventually breach the surface, and typically in the same square as an enemy. The enemy is allowed a perception check vs. the creature’s stealth. If it fails, the target is considered to be flat-footed.
Radiation Field (Ex): The Glowing Phase Rat generates a field of low radiation. This covers only the square it is in, but anyone physically attacking the creature must make a fort save (DC 13), or contract radiation sickness.

Special Abilities
Defensive Phase (Su): The creature can choose, as a standard action, to become insubstantial. While it is in this state, it becomes immune to all physical attacks, although it still suffers regular damage from energy weapons. While in this state, the creature cannot use its natural attacks, and often uses this ability as a purely defensive measure. It is a swift action to turn off this ability.
Diseased (Ex): Whenever they bite a target, there is a flat 20% chance the target will become infected by Bubonic plague. This will become 100% if the creature succeeds with a critical hit with the bite or claw.
Phase (Su): As a standard action, the Phase rat is able to become insubstantial and it can move into the surrounding terrain. It can move through any type of material, even metal, although it cannot use this ability to pass through energy fields. It is fully able to move while hidden, and cannot be detected (except through vibration sense, or life-sense). The creature will eventually breach the surface, and typically in the same square as an enemy. The enemy is allowed a perception check vs. the creature’s stealth. If it fails, the target is considered to be flat-footed.
Phase rats are mutated rats, which have developed a strange and very dangerous ability. They appear to be related to the naked mole rat subspecies, and have pink, slightly wrinkled skin. They have huge whiskers located on the side of their faces, which constantly drag on the ground. This allows them to sense movement from up to 120 feet away. They have large, black eyes and powerful claws, which help them move through the ground with ease. They have large rodent teeth, which can inflict painful bites.
Most of the Phase rats encountered are less than two feet in length and weigh about 10 pounds, although there are two other types which are often encountered. There are the glowing Phase Rats, which are slightly radioactive and are a little larger.
The last type is the brood alphas, which can grow up to five feet in length and weigh around a hundred pounds. They are highly aggressive and quite vicious, and are typically infected with disease.
The Glowing Phase Rats are always encountered alone, as the radiation they produce will kill all other types of Phase rat. Brood Alpha’s are always found accompanied by large packs of Phase Rats.
