Vorpal Sword 5e
He took his vorpal sword in hand:–Jabberwocky, by Lewis Carroll
Long time the manxome foe he sought–
So rested he by the Tumtum tree,
And stood awhile in thought.
Taken from the famous Jabberwocky poem by Lewis Carroll, the Vorpal Sword can go snicker-snack in the hands of your very own adventurer!
The Vorpal Sword is a legendary magic item from the Basic Rules that you likely won’t have access to until very high levels. It gives you a +3 bonus to attack and damage rolls, counts as a magical weapon, and its damage ignores resistance to slashing damage.
The best part is that if you roll a natural 20, you automatically behead your foe. If the DM rules that you can’t behead it (if it doesn’t have a head, for example), it takes an additional 6d8 slashing damage. That extra damage is also multiplied by 2 because a natural 20 is a critical hit, so you’re actually doing 12d8 slashing damage.
