Albrecht's Ethereal Spears

You create 3 ethereal spears that float around you.  On the turn you cast this spell and as an action from there on, you may throw one spear in a 60ft line originating from you.  Each creature within range must make a Dexterity saving throw or take 5d8 force damage and be moved 10 feet away on a fail, or half as much on a success, and is not moved.  Each spear that is thrown disappears after being used, or until the spell ends.

At Higher Levels:  When you cast this spell at 4th level or higher, each spear's damage increases by 1d8 force damage for each level above 3rd.
