Echoes

You target a creature within range, creating up to 7 identical illusions of them. Each illusion appears in an empty space of your choice within 60ft of the target. Illusions have 1AC and 1HP, automatically fail any saving throw, and are destroyed after being the target of any spell. A creature can use an action to make an Wisdom (Investigation) check against your spell save DC to determine the true location of the target.

• The target can attack or cast spells as if they were occupying the space of one of the illusions.
• If the target has the multiattack feature the attacks can originate from separate illusions.
• The target can make an attack of opportunity from any trigger among the illusions.
• As a bonus action the target can teleport to the space of one of the illusions, destroying it. 
• On the target's turn they can move each illusion a distance up to their own speed.
