Armor of Ghosts

While attuned to this armor, you can harness the power of the spirit planes to move in combat. When a creature you can see within 5 feet of you makes an attack against you, you can use your reaction to step into the ethereal plane, reappearing in the material plane in an unoccupied space within 30 feet of your starting location. Once you reappear you can make a weapon attack with the weapon you have equipped on the creature who attacked you. You do not provoke attacks of opportunity using this feature. Once you use this feature, you cannot use it again until you complete a long rest.

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.
