Animated Arrow

You touch an arrow and upon touch the arrow becomes attuned to you and is now in your control. The arrow has a 30 flying speed and levitates 1 foot off the ground. This arrow can pierce right threw monsters and still keep going and requires no bow to fire. Once the arrow hits the target it deals 1d6 piercing damage and +4 to hit. The arrow turns back into a regular arrow once the caster catches it, takes a short or long rest, stops concentrating or when the time limit is reached.
