Elemental Illusion

You must be able to touch the ground, and once you do, you create three illusionary duplicates in the element or your choice(fire, bludgeoning, cold, acid, poison, necrotic, thunder, radiant, force). Roll a d20 to determine when the enemy attacks you, his attack is diverted to a duplicate. 

You must roll  6 or higher to hit one of the three duplicates, 9 or higher for two, and a 12 or higher for one.

The duplicates only have 1 HP, and once they are attacked they explode into elemental detonation, dealing 2d6, with an additional d6 per level of spellcasting slot.
