This magical belt is covered with fur, scales, or leather. While you wear it, you have advantage on saving throws against being charmed or frightened, and you gain the benefits of being cursed with lycanthropy, following the rules described on page 207 of the Monster Manual and page 155 of The Impermissicon, although you are not actually cursed with true lycanthropy. The specific type of lycanthropy you benefit from is determined by the materials used in the belt's creation. You gain all the benefits described for that type of lycanthrope, except you don't gain damage immunities or the shapechanger trait, your alignment doesn't change, and you can't pass on the curse of lycanthropy.

The DM chooses the specific type of lycanthrope or determines it randomly from the options below by rolling a d20 and rerolling any result of 17–20. The type of lycanthrope determines the rarity of the belt.

Curse. The belt is cursed, a fact that is revealed only when you attune to it. The identify spell is deceived by the curse and falsely reveals the item to be a Belt of Giant Strength — either a hill giant or frost giant belt, depending on the rarity of the belt. Attuning to the belt curses you until you are targeted by the remove curse spell or similar magic; if the curse is removed, your attunement to the belt also ends. While cursed, you cannot remove the belt, and you refuse to wear any other belt. You also have vulnerability to bludgeoning, piercing, and slashing damage dealt by attacks using silvered weapons. Finally, during nights when the full moon is out, you experience all the effects of the curse of lycanthropy, including gaining damage immunities, the shapechanger trait (which absorbs this belt into any forms where it doesn't fit), and the change to your alignment. Your DM is free to decide that this places your character under DM control until the sun rises again. During this period, you are able to pass on the curse of lycanthropy just like a true lycanthrope.
