Sergei sent A Real Life on an unsteady rampage through the illusions, trying to dispel as many of them as possible by clawing and punching at whatever it could reach. He couldn't tell the real thing from the fakes, and he didn't exactly have the precision control he needed for that anyway, so he figured this all-over-the-place approach might just work. He listened for the scream of pain that would mean he had hit something real.
Somewhere in the fog, he heard the sharp report of Jayce's pistol ring out, then watched as thick streams of fog followed his movement. Good, that meant the raccoon was still up and fighting. Glancing behind him back towards the fire, Sergei saw Ray fiddling around with....a stone? He didn't know what the other raccoon was doing, but at least he was still up and kicking.
Doing a mental inventory of the team, Sergei realized that three of their number were still unaccounted for: Daryl, Shivali, and that strange masked fur. They might have been stumbling around somewhere, unseen in the fog, but he started worrying that one or more of them had suffered the fate that Red was almost a victim to, being dragged down into a hole in the ground. He thought he might call out to them, but then realized that might not be smart. Their group and the enemy stand user were both listening for each other, trying to gauge the other one's position.
He settled for doubling down on A Real Life's wild attacks. The metal golem's iron claws scored deep marks in several trees as it lashed out in rage at the illusory dopplegangers.
