The Gauntlet of Protection

Divine Aegis. You can use a bonus action to make a spectral shield appear in your hand. While wielding the shield, you gain a +2 bonus to your AC and have resistance to non-magical Bludgeoning, Piercing, and Slashing damage. When you drop the shield, it fades from existence until you summon it again.
  Savior’s Touch. While attuned to this gauntlet, you can cast the cantrip Spare the Dying at will. Once per long rest, instead of stabilizing a creature, you can choose to restore an amount of hit points equal to three times your Constitution modifier to the creature you cast Spare the Dying on.
