The Full Moon

During the full moon the beast becomes to powerful for any Lycanthrope to control or contain. The Lycanthrope is forced to shift to Hybrid form and loses control of themselves.

Losing Control to the Beast

Whenever the Lycanthrope loses control, the DM can take control of the player character. While the beast is in control, it remains intelligent and will flee if the beast feels it’s losing the fight. The beast desires to stay in control, some may even try to make deals and bargain if they’re in a poor position. The beast has access to all of the characters class and racial abilities, including feats, attuned items, and even magic. Until the character knows they’re a lycanthrope they don’t remember the actions of the beast, but relive them as bloody nightmares.

Regaining Control

Characters that lose control from a failed Control Shape check regain control when knocked unconscious, reverting back to their human form. However during the full moon (From Midnight to dawn), they only regain control at dawn, remaining shifted while unconscious.

Shift Action

The Lycanthrope takes an action to change shape, this is referred to as a shift. When a Lycanthrope shifts, they make a Wisdom (Control Shape) check DC 15. If they succeed their items and equipment do not transform with them, restrictive clothing and armor is likely to tear and break, requiring repair before it’s useful again. If they fail, they do not change shape, but if they fail by 5 or more (A total of 10 or lower on the check), the Lycanthrope assumes Hybrid form and loses control. When a Lycanthrope shifts, they can spend up to half their level worth of hit dice, rounded up, to regain hit points. If they lose control, the beast will always use as many hit dice as needed to regain full health.

Embracing or Fighting the Curse

Once a Lycanthrope is aware of their condition, they have two options. They can Fight the curse, refusing to give into their animal instincts. At any time while fighting the curse, the Lycanthrope can make the choice to give in and embrace the curse. Embracing the curse grants the Lycanthrope the ability to use the Control Shape Skill, but they start moving towards the Lycanthropes Alignment and mind set. Once one has given in, it takes the removal of the curse before they return to normal alignment and mind set.

Control Shape Skill

Only Lycanthropes who embrace the curse can gain proficiency in Control Shape, or willingly try to Shift. Characters have Disadvantage on Wisdom (Control Shape) checks if they’re under half health, or are emotional or unfocused. Characters have Advantage on Wisdom (Control Shape) checks if they take 10 minutes and are emotionally calm and collected before making the check.


Alter Self: Allows both those fighting and embracing Lycanthropy to make a Wisdom (Control Shape) check with advantage to shift.
Calm Emotions: Calming a Lycanthrope who’s lost control, gives them a Wisdom (Control Shape) to revert back to normal. This doesn’t work during a full moon (Midnight to dawn).
Command: Add option, Shift: The target spends their next turn attempting to change shape. Target can be fighting or embracing the curse.
Shape Change: Shift without a Wisdom (Control Shape) check.

Removing the Curse

Magic: Remove Curse and Greater Restoration can end one Curse. If the target has embraced the curse, they can make a Wisdom Save against the spell.
Wish: A wish can remove the curse without the target getting a save.
Belladonna: Fresh Belladonna, or Wolfsbane, can be given to the afflicted once a day until their first full moon, to allow them to reroll the Constitution save for the curse. Belladonna however is poisonous, when ingested willingly make a DC 14 constitution save or take 4d6 poison damage and be poisoned for 4 hours, a successful save results in half the poison damage.

Easily Unleashed (Active in: Age of Orion, Strahd)

Virulent Curse

A Lycanthropes claws can also cause the curse. When a target is struck by a claw attack, they must make the Constitution Save or contract Lycanthropy.

Extreme Silver Allergy (Active in: Age of Orion, Strahd)
