DM's Workshop: Petra's Prepwork

The Handmaiden Petra took a bit more time to cobble together, since W.O.I.N. doesn't have full stats for a wide range of lycanthropes.

The system does, however, have race- and monster-building guidelines in the core rulebook. Also, some supplemental material has been written for the game's Patreon-backed magazine, EONS (Monsters in #68, Races in #70). The Baseline Monster Stat Generator can also be found on the system's website, woinrpg.com, under the "Resources" tab.

Wererat

Where there are men and cities and sewers, so too are there rats. It is unknown whether the rat strain of lycanthropy sprang up naturally, was the result of some magical mishap, or diabolical design. Some say the affliction affects rats, and allows them to change into Men, rather than the other way around. Whatever the case, be wary when engaging packs of giant rats, for their bite may carry more than just filth fever….

Statistics:

Size: Medium (Small, in giant rat form)

Attributes: AGI+3, INT+2, END+1

Skill Choices: climbing, running, swimming, scent, stealth, thieving

Exploits:

• Direction Sense. You always know which way is true North, and instinctively know the best/quickest route to take through urban areas. Furthermore, once you have navigated a building or city, you can recall its layout with near perfect accuracy.
• Evasion. Wererats are nimble and adept at dodging. They gain a +2 bonus to either their Melee Defense or their Ranged Defense. This bonus does not stack with other exploits which increase your Defense scores. 
• Regeneration. Young wererat whelps have not yet grown into their full immunity to normal weapons. When in their giant rat form, they can regenerate 1d6 Health at the beginning of their turn from any damage except that inflicted by slivered, holy or psychic attacks.
• Shapechange. You must transform into a giant rat when under the light of the full moon. You cannot speak to humans while in this form, but normal and giant rats will understand you. On nights when the moon is visible but not yet full, you can assume your giant rat form. The duration is a medium countdown of your WIL dice pool in hours. Changing back before the countdown expires, or resisting the change to stay in were-form after the countdown has expired requires a Difficult [16]WIL check. You retain your own mental attributes, but otherwise use those of a giant rat. 

Upon reaching adulthood, the wererat’s Regeneration becomes immunity to non-silver or non-holy weapons while Shapechanged. 

Their Shapechange ability gains a hybrid form, wherein they take the head, clawed hands and feet, and tail of a rat, but stand and walk upright. While in this form, they gain a bite attack that deals 2d6 piercing damage. An opponent brought to 0 HEALTH by a wererat's bite contracts the curse of Lycanthropy. A wererat can use their claws if unarmed, dealing 1d6 slashing damage. Their tail grants a bonus +1d6 to resist attempts to knock them prone or off balance. 

Adult wererats can assume their hybrid or giant rat form day or night, at will, and have a chance to resist the full moon’s forced change, with a successful Strenuous[25] WIL check. However, it is taxing, and they are persistently SICK while resisting the change. This reverts to temporary FATIGUE once the moon sets.

At old age, they retain their immunity while in human form. It is a Demanding[21] WIL check to resist the lunar compulsion to change.

Ranging in size from that of a large house cat to a medium-sized hound, these scavengers find homes in abandoned warehouses, sewers, and swamps throughout the world.

Pack attack. Rats work together well. Any rats adjacent to the victim count as flanking, gaining the +1d6 bonus to attack. When 3 or more rats are adjacent to the victim, the victim becomes overwhelmed, and is rendered Fatigued at the start of its turn. 

Filth fever. On a critical hit, or if reduced to 0 HEALTH, the victim contracts Filth fever, which causes waves of nausea, fever, and chills the next morning. The victim is persistently SICK and FATIGUED until the disease runs its course (a slow END countdown). A Demanding [21] END check is required daily.
