The second Oz yelled for Luke to take cover, Jeff prepped his hand gauntlet, aimed, and then fired it upwards at the ceiling using a burst of wind to strengthen the trajectory. It then grabbed hold of it by using nanobots which had shifted the onto head of the grappling hook to transform it into a super magnet, thus increasing the grip in order to help him overcome the gravity that was trying to ground him and allowing the inventor to pull himself to the ceiling where he would be hopefully away from the worst of the gravity's pull. Either way, he knew he'd most likely be able to feel at least part of the vortex, regardless of location, and would have to rely on sage mode for any super swift movements beyond this point. 
[color=fff79a]"As expected... I knew this would be coming soon enough, but it's good to see just how exactly it works now."[/color], the inventor stated showing high interest in Oz and his powers. This was clearly one of the most unique of the group's powers and he couldn't help but take more and more interest in this sparing match as time went on.
In the meanwhile, the particles that were being forced back to where the vortex formed then began to merge together and formed into a small sentry gun which then magnetized itself to the ground to stop itself from being pulled any further away. The gun then proceed to beep a few times as it took aim and then fired a small barrage of arcane bullets at Oz from bellow. This gave Jeff the time to magnetize his boots so that he'd be able to run on the ceiling and keep more so out of range of Oz.
