Telekinetic Explosion

You choose a space within range and cause an erruption of telekinetic energy that pushes away creatures and objects. A creature that occupies the space you choose must make a Constitution Saving Throw or be knocked prone. An object (that isn't worn or carried) that occupies that space takes 2d4 force damage. Any other creature within 5 feet of the explosion must make a Constitution Saving Throw or be pushed away 10 feet from the center of the explosion. Any other (that isn't worn or carried) object within 5 feet of the explosion takes 1d4 force damage.
A "large" or larger creature has advantage on the Saving Throw

At higher Levels: If you cast this spell at 4th Level or higher, you can impose disadvantage on the Saving Throws of any creature that is affected by the spell (or cancel out the advantage of a "large" or larger creature). Also at 4th Level or higher the force damage for objects that are affected by the spell increases by 2d4.
