Cosmo's Momentary Duplicate

Choose a willing creature within range. For an instant, the creature vanishes. It then reappears along with an exact illusory duplicate of itself occupying the same space. For the spell's duration, the duplicate mimics the actions and movements of the creature exactly. Any attack rolls made against the target have disadvantage and all of its melee attacks have advantage.

If an attack hits the creature while the duplicate persists, roll a d20. On a 10 or higher, the attack hits the duplicate instead of the target and it is destroyed, ending the spell.

At higher levels. When you cast this spell using a spell slot of 3rd level or higher, you may choose one additional target for every two slot levels above 2nd.
