9th-level enchantment (Cleric,Sorcerer,Warlock,Wizard)
- Casting Time: 1 action
- Range: 5 feet
- Components: V, M (a slashing weapon)
- Duration: Concentration, up to 1 minute
As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails. The weapon attack ignores resistance to slashing damage. On a hit, the target suffers the attack's normal effects and takes an extra 6d8 slashing damage from the hit. On a miss, the spell ends. If the initial attack hits, the weapon retains its enchantment for the duration. Until the spell ends, the weapon ignores resistance to slashing damage, and once per turn, when you hit a creature with a weapon attack, you can use a bonus action to cause that creature to take an extra 6d8 slashing damage from the hit. In addition, while this spell is active (including during the initial attack), if you attack a creature that has at least one head with the 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.
