Prerequisites: 17th-level, Strength or Dexterity of 19
When you hit a creature with a melee weapon attack, you can expend one Exploit Die to strike with legendary force, dealing bonus damage equal to four Exploit Dice.
If this attack reduces the creature’s remaining hit points to 50 or less, 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 Exploit’s effects, but still take the damage.
