After long reserches the greatests magicians of the world have create a new spell (or if we want to specify, a variation of levitate).You can choose an object or creature that you can see,  it is immune to the gravity and the air friction. The spell can only be used to an object that weighs less to 500 pounds. An unwilling creature that succeeds on a Constitution saving throw is unaffected. The target can move only by pushing or pull against a obgect or surface it can reach. It can also be moved by other creatures.

When the spell ends, the target falls down and takes damege equal to the radicall square of 2h/g, where h is the height and g is the gravity accelleration.

The spell is effective only if you can see the target (also after you cast it).
