### Decapitation On a successful attack, the target may be decapitated. - Against a target of stone or metal, a decapitation only occurs on a critical hit (regardless of size). - Against a target of size large or bigger, a decapitation only occurs on a natural 19 or 20. - Against a medium-sized or smaller target, a decapitation occurs on a natural 18, 19, or 20 - Some creatures may either be immune to or unaffected by decapitation (ex: creatures without a head, elementals).
