Empty Cicada

You touch a dummy and prepare it to take your place, the dummy disappears. When you're hit by an attack, you can use your reaction to cause the dummy to reappear in a puff of smoke. It is hit by the attack instead, you can teleport up to 10 feet to an unoccupied space you can see, and the spell ends. If you don't cause the dummy to reappear before the spell ends, it reappears in your space.
