Amulet of Armor

At the end of a long rest you can attune this amulet to a single suit of worn armor. As an action, you may banish this armor to, or summon it from, the ethereal plane. The armor may only be summoned if you are not currently wearing armor.  When the armor is summoned, it appears on you as if you had donned it normally.

Creatures or spells that allow sight into the ethereal plane will easily see the suit of armor surrounding the wearer's form.
