Current of Force

Push a creature you can see with a dark current of force. Make a ranged spell attack against the target. On a hit, the target takes 1d6 force damage, and is pushed 15ft and knocked prone. If the target impacts a wall or some other type of barrier before the current finishes pushing it, takes 1d6 damage for every 5ft it would have been pushed further and is not knocked prone.

When cast at a higher level you can send out multiple currents, one more current for every spell level above 2nd level. (uncast at 3rd level you'd be able to cast two currents, 4th level would get you three currents)
