Duplicity

On a successful hit with the Metal Vessel of Memnor, you may create a perfect illusion of yourself that lasts for 2 rounds at the cost of 1 charge. Each successful hit thereafter renews the illusion. The illusion appears in an unoccupied space that you can see within 30 feet of you. As a bonus action on your turn, you can move the illusion up to 30 feet to a space you can see, but it must remain within 60 feet of you.

when both you and your illusion are within 5 feet of a creature that can see the illusion, you have advantage on attack rolls against that creature, given how distracting the illusion is to the target.
