Arcane Aard

You shoot forth from your arcane focus, such as a staff, wand or ring etc, a wave of transparent, telekinetic force, ramming any targets off their feet within a 60 ft range. 

This can either be in the shape of a 30 ft cone in any direction you can see, or as a 30 ft sphere around yourself in the centre. 

Any creature within range must make a dexterity save. They suffer 4d10 force damage, suffering an additional 2d6 bludgeoning damage from any object or terrain they may collide with. On a successful save they only take half that damage. 

If you cast this spell at level 2 or higher , you do an  2d10 force damage and 2d6 bludgeoning damage, and creatures who fail their dexterity save are knocked prone.
