Requires Attunement

You gain a +3 bonus to Attack and Damage Rolls made with this Magic Weapon. In addition, the weapon ignores Resistance to slashing damage.

When you Attack a creature that has at least one head with this weapon and roll a 20 on the Attack roll, you cut off one of the creature's heads. The creature dies if it can't survive without The Lost head. A creature is immune to this Effect if it is immune to slashing damage, doesn't have or need a head, has legendary Actions, or the DM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 6d8 slashing damage from the hit.
