Duskstep Volley

You loose a volley of phantom violet arrows that fans out in a 60-foot cone from you before dissolving into shadow-mist. Each creature of your choice in the cone must make a Dexterity saving throw, taking 4d8 Force damage on a failed save, or half as much damage on a successful one. Immediately after the volley strikes, you teleport up to 30 feet to an unoccupied space you can see that is in Dim Light or Darkness.At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the Force damage increases by 1d8 for each slot level above 3rd.
