Advanced
• Perfect Poison: as Lupus Gift "Venom", except that the victim suffers one Health Level of damage per minute and the wounds are aggravated. In addition, the Ratkin may lick a blade to coat the weapon in this toxin, to the same effect. A weapon thus treated retains the toxin for up to an hour.
• Plague Bite: as Lupus Gift "Venom", except that the disease inflicted causes aggravated wounds.
Rites
In addition to some of the common Rites used by Garou, Ratkin have access to a few rituals unique to them.
Basic
• Birthing Plague (Accord) : This Rite allows a prospective Ratkin Kinfolk to attempt their First Change by summoning the Rat Totem to bite the subject. It is entirely up to the Storyteller whether this Rite will be successful, or if the victim will die of the plague.
• Purified Body (Accord) : By spending a Gnosis Trait, the Ratkin may cleanse a target of all toxins. A variant of this Rite is thought to exist which instead cures all normal diseases (though the Birthing Plague is unaffacted).
• Bolt-Hole (Mystical) : as Glass Walker (Advanced) Gift "Long Running", except that the amount of reduction is determined by an Extended Static Mental Test. The Ratkin (and other others who travel with her) pass through secret Umbral tunnels and thus avoid all other Umbral traffic.
• Pain Dagger (Mystical) : This enables the Ratkin to enchant a specially prepared bladed weapon (sword, dagger, etc). Once enchanted the weapon oozes minute amounts of poison at all times, inflicting aggravated wounds. This Rite costs two Gnosis Trait to perform: one to enchant the blade and another to attune it to a particular Ratkin, who is thereafter not affected by the poison on that weapon

Breeds

Homid: a Ratkin born of a human parent.
Beginning Gnosis: 1

Metis: a Ratkin born of Ratkin parents.
Beginning Gnosis: 5
Ratkin can mate freely with whomever they choose. It is well known that a metis Ratkin has less of a chance to survive the Birthing Plague, and so there are fewer of this breed than others. Their natural form is Crinos, like other metis. Rodens: a Ratkin born of a rat parent.
Beginning Gnosis: 3
Rodens Ratkin can instantly shape-change into rats and speak in squeaky voices when in human shape.
The Ratkin have three basic forms: Homid, a Crinos half form, and a Rodens shape.
Homid: their human body. Basic stats as in Werewolf. Many of them have pinched features. They are all very short in this form.

Crinos: the Ratkin Crinos form is a lithe, extremely quick amalgam of rat and man. The Crinos' eyes are blood-red, and glow slightly in the dark.
Str. +1, Sta. +1, Dex. +4, Cha. -2, App. O, Per. +1; Diff. 6.
The bite of the Crinos form causes aggravated wounds (Str. +i ), but the claws cause normal damage. The Ratkin's pink tail becomes totally prehensile in this form, and may even wield weapons at +2 to the attack difficulty, the strength of the tail being roughly half the Strength attribute. Some Ratkin have been trained to untie knots with their tails. Rodens: the form favored by most Ratkin, it is that of a normal-looking wharf rat.
Str. -1, Sta. +2, Dex. +2, Cha. -3, Per. +3; Diff. 6.
Both the claws and the teeth of the Rodens form cause aggravated damage (Strength as damage).
Aspects

Ratkin choose a specific career within the Ratkin community based on their talents and abilities, and
hallucinations they experience during their Rite of the Birthing Plague. They often have an apprenticeship with one of their Aspect to help them learn their Way. The Ratkin's Aspect defines what rites he knows and what his starting Rage is.

Warrior: Ratkin Warriors are the defenders of their kind, well-versed in combat. They usually they learn guerrilla tactics at the hands of their masters and learn to utilize the environment of the underground world to aid them in hunt and battle. They originated the Rite of the Pain-Dagger. A Ratkin is not considered an adult
Warrior until she makes her own such dagger.
Beginning Rage: 5

Gifts

Cloak of Shadows (Level One) -- By spending a Gnosis point and rolling a Manipulation + Stealth versus any viewer's Perception + Alertness, the Ratkin can cloak himself, and anything he touches, in shadow. The success of the cloaking depends on the number of successes generated by the roll, as below:
Successes..........Area Cloaked
1......................Just the Ratkin
2 ....................One other human-sized person or an object roughly the same size.
3.................Three other human-sized people or a small car.
4................Eight or mote humans or a step van
5................12 or more humans or a tractor-trailer truck.

Darksight (Level One) -- By spending a Willpower point, the Ratkin can see in the dark as if it were light. This Gift gathers ambient light and uses the dim light of the Umbra to aid sight.

Shadow Throw (Level One) -- By spending a point of Rage, the Ratkin can cause a dagger to be surrounded with a shadowy field of force. He can then target a single person with a Perception + Athletics attack roll and throw the dagger. It will be propelled by the shadowy force, and if it hits its target, will do aggravated damage.

Smell Poison (Level One) -- By spending a point of Gnosis, the wererat can sense any kind of poisonous or toxic material in the area. Rolling on Perception + Medicine may give clues to the nature of the poison involved.

Attunement (Level Two) -- By standing in a particular area, the character can commune
with the spirits of the area, thus getting an overview of what exists or has happened in the area -- rough population, secret tunnels, places of note and so on. This Gift is taught by a Rat-spirit.
System: The Ratkin spends one Gnosis point and rolls Perception + Streetwise (difficulty
6). The amount of information gained depends on the number of successes; on a botch, the spirits lie. This Gift may only be used in urban areas, as the Ratkin have become desensitized to the wilderness.

Fly-Feet (Level Two) --This allows a Ratkin to climb vertical surfaces as if she were an insect. Roll Dexterity + Athletics. The difficulty depends on the surface. Wood and rough stone would be five, glass and smooth marble would be nine. Upside down movement adds plus one or two to the difficulty. The ability lasts for one scene. Movement rate is halved unless five or more successes are rolled.

Backbite (Level Three) -- The wererat can disappear and instantly reappear behind an opponent. The Ratkin then has an open shot at an opponent's back. This trick involves instantly traversing the Umbra. The Ratkin must spend two points of Rage to use this Gift.

Squeeze (Level Three) -- By spending a Gnosis point and rolling Dexterity + Enigmas, a Ratkin may pass through a wall, door, or other obstacle by squeezing through the Umbra. Three or more successes allows the Ratkin to pull another person along with him.

Call Kinfolk (Level Four) -- Using this Gift, the wererat can summon a horde of rats out of the Umbra to his area who will attack according to the wishes of the Ratkin. This costs one Gnosis point. A Manipulation + Animal Ken roll shows the number of rats who respond to the call.
Successes.......Number of Rats
1...........................5
2 ..........................20
3...........................50
4...........................100
5...........................150
When the rats attack as a swarm, they can take up to five wound levels per success on the summons; they have an attack dice pool equal to the number of summons successes +2 and can dodge at the same rating. The damage ranges from two to four dice.

Gnaw (Level Four) -- The Ratkin may strengthen her jaws to the point that, given time,
she can chew through just about anything. In addition, her jaws do more damage in
combat. This Gift is taught by a Rat-spirit.
System: The Ratkin spends one Willpower point and rolls Stamina + 4 against a variable
difficulty (3 for wood, 6 for steel cables, 9 for a titanium door). The length of time it
takes to gnaw through something is up to the Storyteller. When employing this power in
combat, the Ratkin's bite does an extra die of damage.

Mind of the Tunnels (Level Four)-- By spending a Willpower point and rolling Intelligence + Empathy,
difficulty seven, a Ratkin can open a rapport with any other Ratkin he knows. Since most Ratkin know each other, this allows access to many other wererats. Rapport is complete: emotional, mental, and physical information can be shared. It is possible for one Ratkin to borrow another Ratkin's senses -- even at a great distance.
With every success beyond the first, another Ratkin may be brought into the rapport. The wererat who initiates the contact serves as the central point for all information flowing through the network and can control what each wererat receives from the others. The information shared by each Ratkin is up to the initiating Ratkin -- no information can be
gained by force.

Plague Bite (Level Five) -- By spending a Gnosis point, the wererat causes his incisors to transmit a foul plague that instantly attacks the victim's central nervous system. The victim lose ones aggravated health level an hour and cannot stop shaking -- he is plus three to all attack difficulties during this time. Ooze pours from his mucous membranes, and he drools continuously.
A successful Bite attack must be made in order for this Gift to work. Unless the victim is immediately taken to the hospital, it is likely he will die. The plague can be treated by modem science. If ordinary rats eat the flesh of a corpse who died of this plague, they will become contagious. Ratkin (and their Ratkin folk) are automatically immune to this Plague.
The Garou Gift: Resist Toxin will heal this plague. Otherwise, the Garou takes aggravated health level damage until she is Incapacitated, but she will not die. Her supernatural healing ability will eventually destroy the disease. Needless to say, Ratkin are often killed on sight by Garou on the grounds the Ratkin are "disease-ridden vermin."

Perfect Poison (Level Five) -- By spending three Gnosis points, the Ratkin's spittle becomes odorless, colorless, fastacting, and nearly undetectable poison. Victims lose two aggravated wound levels per round when infected, and may only resist with a Stamina + 2 (or Primal-Urge for shapeshifters) roll --for each success the victim gets, he resists a wound level of damage.
If a Garou victim can continue to resist damage for 10 rounds, the poison is effectively jettisoned from his body. Spending Rage will give an automatic success to the resistance roll per point spent, but the Garou must make a frenzy roll. The Garou Gift Resist Toxin is proof against this Gift, but Mother's Touch is not. Sometimes a Ratkin will lick a blade with this Gift, coating it with the poison, which lasts for three hours while exposed to air.
