Oz ducked under the first blade able to see it coming clearly, the second two were a bit more of a challenge. Jeff was clearly a faster opponent but he wasn't using anything with enough potency to cause real damage. With his free hand he projected a shield in front of himself that splashed the wind out to either side as it connected. He allowed the projected shield to drop as he brought his free hand down to the developed sphere of energy. [color=violet]"Luke, you might want to brace yourself."[/color] He warned.

Oz chanted. The orb burst in his hands as the energy spread around Jeff's direct area and drew him toward the floor at his feet. Even the air in the large area was unsettled, drawing the unnoticed particles back to Jeff. The spinning force would pummel him as it slammed him toward the ground. It would either suppress him or he would need a way to overcome it, some technique - at least until Oz dropped the vortex.
