A ring of spinning wind and eldritch magic appears around your forearm that you can fling towards a creature within range. Make a ranged spell attack against the target. On hit, the target takes 1d6 slashing damage. (If you have warlock invocations that effect Eldritch Blast, they will have the same effect on this spell) 

You produce more rings the higher in levels you progress: 2 rings at 5th level, 3 rings at 11th level, and 4 rings at 17th level. (These rings can be directed at the same target or different targets. Each ring requires its own attack role.)
