Blasting Shot

You shoot with the weapon that is the material component of the spell. On a hit, your target takes damage from the weapon and then is surrounded by a field of psychic energy until your turn starts. If the target moves willingly before then, it takes additional 1d8 psychic damage and the spell ends. 

At 5th level, your ranged attack deals an extra 1d8 psychic and the damage for moving goes to 2d8 psychic. These numbers go up by 1d8 each at 11th level and 17th level.
