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.
