Omenbringer's Mantle

This raven-feathered mantle is almost iridescent. While wearing this mantle, you have resistance to necrotic damage and descend 60 feet per round when you fall, taking no damage from falling.

In addition, while wearing the mantle, you can use an action to cast the find familiar spell from it. When you do, the familiar takes the form of a raven. If the familiar falls to 0 hit points, it can’t be summoned again until the next dusk. Otherwise, the familiar remains so long as you are attuned to the mantle.
