Vorpal Longsword (A)

Legendary

You gain a +3 bonus to Attack and Damage Rolls made with this Magic Weapon. In addition, the weapon ignores Resistance to slashing damage. When you Attack a creature that has at least one head with this 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. Such a creature instead takes an extra 6d8 slashing damage from the hit.

Ring of Invisibility

Legendary

This cold steel ring is invisible when unworn but becomes visible when slipped onto the wearer’s finger. While wearing this ring, you can turn invisible as an action. Anything you are wearing or carrying – apart from this ring – is invisible with you. You remain invisible until the ring is removed, until you attack or cast a spell, or until you use a bonus action to become visible again. To avoid being spotted while invisible, you must cover the ring with a glove.
