Tenseiga (5e Equipment)
From D&D Wiki
Weapon (katana), legendary (requires attunement by a creature with a demonic ancestor)
This masterwork katana, which has the nickname of the "healing sword", is the brother of Tessaiga but appears as a beautiful new katana instead of the ancient appearance of its sibling. This sword encourages you to do good things for others.
Healing Blade. You can use this weapon to heal creatures instead of harming them. You may choose to heal a creature instead of dealing damage to them with this weapon. You may use this effect 3 times, and this weapon regains all expended uses at dawn.
Resurrection. Tenseiga could restore the life of the recently deceased by destroying the reapers who took the souls of the dead. You may cast the revivify spell through this weapon without material components. The weapon regains use of this effect at dawn.
Purification. As an action, each undead that can see or hear you within 30 feet of you must make a DC 16 Wisdom saving throw. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage. Also, if the undead was of CR 2 or less and failed its saving throw, it is destroyed instead.
A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, the creature can use the Dodge action.
The weapon regains use of this effect at dawn.
Protective Barrier. When you drop to 0 hit points, Tenseiga will teleport you to a unoccupied place of your choice within 40 feet and create a wall of force around you. Until the start of your next turn, only creatures of your choice may enter the barrier. The weapon regains use of this effect at dawn.
