Lycanthropes — Were-Creatures, Curses & Rules
The beast may be someone the village knows. A lycanthrope can live much of its life as an ordinary person, even while possessing the power—or suffering the curse—of an animal shape.
Some were-creatures inherit controlled transformation. Others are afflicted without knowing it and discover the truth only after a lost night. Neither condition alone determines an individual’s character. The hunter might be a murderer, a protector, a terrified neighbour or a person who has learned to profit from a frightening secret.
This family guide explains the different rules, useful clues and encounter choices. The individual lycanthropes below have their own statistics and habitats.
Lycanthropy Rules by Edition
There is no single generic lycanthrope stat block. The notes below identify how each edition handles the family; use the linked individual creature for attacks, saves and challenge. Do not import a full-moon, silver or cure rule from another edition.
D&D 5.5e / 2024
Example creature: The 2024 werewolf is a Medium or Small Monstrosity (Lycanthrope), CR 3. Its Shape-Shift uses a Bonus Action; this is not a family-wide template.
Curse: A target of the werewolf’s Bite makes a DC 12 Constitution saving throw. On failure it becomes cursed; if the cursed target drops to 0 Hit Points, it becomes a werewolf under the DM’s control with 10 Hit Points. Success gives that creature immunity to that werewolf’s curse for 24 hours. Other were-creatures require their own wording.
Treatment: The 2024 DM’s Toolbox leaves it to the DM how Remove Curse affects a creature with cursed origins. A recent bite, hereditary lycanthropy and a plot-driven transformation need not have the same remedy.
D&D 5e / 2014
Example creature: The 2014 werewolf is a Medium humanoid (human, shapechanger), CR 3. It uses an Action to shift into wolf or hybrid form or return to humanoid form.
Curse: Its bite in wolf or hybrid form requires a DC 12 Constitution saving throw from a humanoid, or the target is cursed with werewolf lycanthropy. Its printed immunities protect it from nonmagical bludgeoning, piercing and slashing attacks that aren’t silvered. Apply the actual defences on the selected creature, not an assumed universal template.
In play: Resolve loss of control and a player character’s lasting curse using this edition’s lycanthrope guidance, rather than Pathfinder’s Fortitude and Will saves.
Pathfinder 1e
Template: The inherited or acquired lycanthrope template applies to a humanoid. Its CR equals the higher of the base creature or base animal’s CR, plus 1. Natural lycanthropes receive DR 10/silver in animal or hybrid form; afflicted ones receive DR 5/silver.
Transmission: A natural lycanthrope’s bite in animal or hybrid form can infect an eligible humanoid (Fortitude DC 15 negates, subject to size limits). A scratch or the bite of an afflicted lycanthrope does not automatically transmit the template’s curse.
Onset and recovery: An infected creature first transforms at the next full moon. It usually forgets the episode unless it succeeds on a DC 20 Will save. Remove disease or heal from a cleric of at least 12th level works within three days; the template also gives a Fortitude-save route involving wolfsbane. Wolfsbane is poisonous and should never be treated as safe real-world medicine.
D&D 3.5e
Template: A humanoid or giant gains a compatible animal form, hybrid form and related animal Hit Dice. Natural and afflicted lycanthropes have different damage reduction: DR 10/silver and DR 5/silver, respectively, in animal or hybrid form.
Transmission: The bite of a natural lycanthrope in animal or hybrid form passes the curse on a failed DC 15 Fortitude save if size requirements are met. Afflicted lycanthropes do not pass the curse onward using this template.
Control and recovery: First symptoms emerge at the next full moon. An aware afflicted creature may learn Control Shape; checks for voluntary and forced transformation differ. Remove disease or heal can work early, whereas remove curse or break enchantment at the full moon uses special conditions and a Will save. This edition also has level-adjustment and animal-Hit-Dice consequences for player characters.
Natural and Afflicted Lycanthropes
A natural lycanthrope grows up with its transformation as an ordinary part of life, even if the surrounding community views that life with fear. Such a creature might conceal its nature, take steps to protect neighbours or exploit powers that others do not possess. It does not automatically become a killer when it changes form.
An afflicted lycanthrope has to cope with a change it may not understand. Missing time, damaged clothing and a door barred from the inside may be signs; none alone proves guilt. The precise role of moonlight and memory depends on the chosen edition and the particular curse.
Bites spread lycanthropy in several game systems, but folklore also speaks of inheritance, sorcery and skins or belts that change their wearer. The site’s Curse of Lycanthropy spell is a separate legacy-d20 effect, not an ability belonging to every were-creature.
Where Lycanthropes Are Found
Their animal shapes suggest habitats; their human lives complicate the picture. A wereboar may work a farm near the woodland it defends. A wererat can find shelter beneath a crowded town. A wereshark can hide its identity in a port where crews change with the tide. None of these examples establishes a species-wide campaign population.
The setting preserves Peter Stumpp of Bedburg and Gilles Garnier in French tradition as routes into local werewolf stories. An accusation in a chronicle is not proof that a supernatural predator lived there. When locating an actual encounter, first choose a named Bestiary creature and verify its local context.
Behaviour and Warning Signs
Ask what exposure would cost the person beneath the fur. A frightened household may hide a relative through the full moon; a natural predator might deliberately leave false tracks to direct hunters toward an innocent suspect. A cautious were-creature learns where silver weapons are stored, who watches the road and which neighbours will protect its secret.
Evidence should be something players can investigate, not a verdict from a single ominous birthmark. A lock opened from the inside, tracks that change on firm ground, an eyewitness whose timing fails to match the moon, or a wounded suspect who can account for the injury can move an investigation forward. Ordinary animals, other monsters and deliberate lies remain possible explanations.
If Violence Starts
A lycanthrope who values secrecy may escape rather than fight in front of witnesses. One that attacks chooses favourable terrain, isolates a vulnerable target and tests whether its opponents can bypass its defences. Use the species-specific senses and movement: a wererat can exploit tight passages; a wereboar can hold ground and charge; a wereshark would rather pull the fight towards water.
Silver is not mechanically interchangeable between editions. It overcomes particular damage immunities in 2014 D&D, damage reduction in Pathfinder and 3.5e, and has no automatic extra effect unless a 2024 creature’s own statistics say so. Similarly, do not grant an animal form an extra attack or free transformation unless the stat block permits it.
When wounded, decide whether the creature protects family, bargains, flees through a prepared exit or fights because it genuinely has nowhere left to go. A chase, capture or confession may tell a stronger story than a fight to the death.
Using Lycanthropes in Play
The Locked Room
Every few weeks a respectable household takes food into a locked outbuilding. A frightened relative wants the party to leave it alone; the neighbours insist someone is being held prisoner. Who holds the key, who consented to confinement, and what will happen if the lock is opened after dark?
The Wrong Beast
Livestock is killed and a local outcast is accused. The tracks do not agree with the wounds. Following both trails can uncover a genuine shapechanger, an ordinary predator or a staged attack—without treating the accusation as a foregone conclusion.
The Calculated Hunt
A natural lycanthrope uses a daytime profession to learn which travellers are isolated. Its first defence is an alibi, its second an escape route. Confronting it in public may endanger bystanders; taking away its secret gives the players a negotiating advantage.
For less experienced adventurers, the mystery may be the whole encounter. For a stronger party, companions, terrain and conflicting objectives matter more than a larger pile of Hit Points. Judge encounter difficulty from the actual named creature’s CR and edition.
Player Characters and the Curse
Before a player character contracts lycanthropy, decide together who controls the character during an involuntary change and whether treatment, suppression or acceptance is possible. Losing control should never be introduced as an unexplained punishment after the fact. The character’s relationships, obligations and fears can be compelling without handing out a monster’s full attacks and defences as free player benefits.

Folklore and Transformation
European tales have attributed wolf-changing to curses, inherited fates, forbidden magic and enchanted skins or belts. Full-moon transformation is familiar in modern fiction, but older traditions varied considerably. Historical trials and frightening stories also preserve human fear and accusation, not reliable testimony of supernatural events. A campaign can play with that uncertainty while keeping the actual game mechanics clear.
