Blade of Eldritch

Through the focusing the crackling energy you refine it and form a magical blade. The arcane blade's shape is determined by the user's imagination but will not affect the damage nor range.  You can choose to dissipate the blade whenever you want as a bonus action, but to reform it must be an action. As an action you may slice an object, or make a melee spell attack against a target. On hit the target takes 2d6 force damage. The blade sheds a bright light for 5 feet. 

At Higher Levels: When casting at 5th level or higher the component is no longer necessary to create the blade
