Prerequisites: Strength of 19
When you score a critical hit with a weapon attack, you can spend a Maneuver Die to strike with legendary force, dealing bonus damage equal to three times your Maneuver Die.
If the damage of this Maneuver reduces the target’s remaining hit points to 50 or fewer, you cut off one of its heads. If the creature cannot survive without the lost head, it is killed.
Creatures can use a Legendary Resistance to avoid being beheaded. Creatures that don’t have or don’t need a head are immune to this Maneuver’s effects, but still take the damage.
