Lycan Maul

Made from the claws, teeth, and bones of lycanthropes, these weapons are particularly effective against other lycanthropes or vampires. You gain a +2 bonus to attack and damage rolls made with this weapon. Additionally, on a successful attack against a lycanthrope, the target is forced back into its human form unless it succeeds on a DC 10 Charisma saving throw. Also, damage done to vampires with lycan weapons cannot be regenerated until the creature finishes a short rest.

Heavy: Creatures that are Small or Tiny have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small or Tiny creature to use effectively.

Two-Handed: This weapon requires two hands when you attack with it.
