Each time a creature targets you with an attack during the spell’s duration, roll a d20 to determine whether the attack instead targets one of your duplicates. If you have three duplicates, you must roll a 6 or higher to change the attack’s target to a duplicate. With two duplicates, you must roll an 8 or higher. With one duplicate, you must roll an 11 or higher.   A duplicate’s AC equals 13 + your Dexterity modifier. If an attack hits a duplicate, the duplicate is destroyed. A duplicate can also be destroyed by area effects. The spell ends when all three duplicates are destroyed.   A creature is unaffected by this spell if it can’t see or if it relies on senses other than sight, such as blindsight, or if it can perceive illusions as false, as with truesight.
