It looks a bit like the Blades spell from Fable to me. They used to skewer the enemy too. And able 1 had the Ghost sword, which was ghostly swords that followed you around and autonomously attacked enemies that got close to you.

So yeah, I can imagine it rather easily, and that is an impressive ability. If he really did have that, I'd be scared for the RWBY girls.
