After maintaining the shield for a moment an uncanny thought occurred to Oz. He had been standing over her as the shield went down. She wasn't trapped yet, her spikes had made sure of that. Even then she attacked Oz with a spike but it missed. Oz didn't even need to dodge it. Could she actually tell where he was with part of the shield over her? Maybe he didn't need the shield at all for anything other than to contain her. It was a gamble but it brought to mind what Ada herself did to her goop earlier. She turned it into gaseous form to give her more cover on the field.
Oz, still standing atop the formed barrier, flexed his good hand. It didn't need to be much, just enough that it would leave Ada nearly helpless. He summoned a mote of energy into his hand, focusing on making it do what he wanted. It flipped, flexed, spun and twisted until he grasped the thought he was looking for. The mote broke up into tiny bits but maintained a mist-like consistency. Oz grinned. It wasn't wet, nor was it a gas. That sure as hell didn't mean he couldn't mimic it.
The disc rose up away from the shield at Oz's will. It wouldn't do if he got impaled from a raging Ada after this. He extended his hand over the edge and pushed against the power inside him. A haze of blue energy poured out of his hand. It drifted downward toward the dome and settled in a thick, glowing fog. It wasn't that the energy was wet but being in its presence felt thick and heavy nonetheless. Plus it was made out of veil and Ada hated that stuff! It was no solid shield but he imagined that being surrounded by this would make Ada feel like she were seeing through viscous mud.
