Boomerang Blade

2-point conjuration (creation)
Casting time:	action
Range:	60 feet
Components:	V, S
Duration:	1 round

You form a boomerang-like blade which flies to a space in range that you designate. The blade travels through any space occupied by a creature or object; the blade passes through objects harmlessly, but not creatures. Any creature in a 5-foot line between you and the chosen space must succeed on a Dexterity save or take 3d6 slashing damage. A creature in the chosen space has disadvantage on this save.
 The blade continues to hover and spin at that point until the start of your next turn. Any creature which would enter the same space as the blade must make the same save or take the same slashing damage.
 At the start of your next turn, the blade flies back to you in a straight line, then vanishes immediately before it would touch you. Any creature in a 5-foot line between that point and you must succeed on a Dexterity save or (again) take 3d6 slashing damage. If you are not within 300 feet of the point, the blade instead falls to the ground harmlessly, then vanishes.
 Upcast. You can upcast this spell by expending extra spell points when you cast it. For each extra point, increase every damage roll by 1d6.
