Invoking an ancient, forbidden ritual, you transform a humanoid you touch into a lycanthrope. If the target is not illuminated by the light of the full moon when the spell takes effect, the spell fails and the target suffers four levels of exhaustion.   Choose a Beast with a Challenge Rating of 1 or lower. The target is cursed with a form of lycanthropy associated with that creature. This curse cannot be removed by any means short of the wish spell or the remove curse spell cast at 9th level. The target gains the following traits:   Lycanthropy. The target can use its action to polymorph into the chosen beast, into a hybrid of the beast and its humanoid form, or back into its true form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies. While in beast form, it is limited in the actions it can perform by the nature of its true form; it can’t speak, cast spells, or take any other action that requires hands or speech unless its new form is capable of those actions. While in hybrid form, the target maintains all its statistics, but also gains access to the actions and traits found in the statistics of the chosen Beast.   When transformed into its hybrid or bestial shape, it has resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons that are not silvered. If the target starts its turn in contact with silver or is damaged by a silvered weapon, it is poisoned until the start of its next turn.   Mooncursed. While under the full moon, the target is forced into a feral version of its hybrid form. It loses the ability to speak in its hybrid form, its Intelligence, Wisdom, and Charisma scores become those of the chosen Beast, and it cannot return to its humanoid form. In this state, the target loses its sense of self and actively hunts other creatures, slaughtering them violently before moving on to its next target.   Any creature bitten by the target in this state must make a DC 12 Constitution saving throw. On a failure, it is afflicted with the same kind of lycanthropy.
