Compelled Backflip

You target a creature within 60ft of you that you can see. The spell ends if the target is immune to being charmed. Both you and the target are forced to make Dexterity (Acrobatics) check (You can use your spellcasting modifier instead of dexterity). The one with the lower result is dealt the difference between the rolls x2.  The one with the higher result is healed for the same amount.
