Uncanny Reflection

You create 3 replicas of yourself that move independantly from each other (they have the same speed as the caster). The caster can then choose which image is the real one right after the casting. It is almost impossible to distinguish the real one of the fakes ones (Investigation dc 25). When attacking, the caster can choose from which image the attack real attack will come. The replicas share the caster's AC, but only have 1 HP. They are immune to zone targetting spells. Each turn, as a bonus action, the caster can choose to trade place with a replica.
