Deny gravity.

Select a target that you can see in range. This target must succeed on a Dex spell save or immediately be lifted up to 20 ft into the air. Their movement speed is reduced to zero while in the air. All attacks made on this target while in the air work as if the target is prone. At the end of the round the target is slammed down  and takes 1D8 Force Damage per 5 ft they fall. 

When cast at higher levels, the upper limit of how high the target rises increases by 10 for every spell slot level over 2nd level.
