It was tricky when you have to fight a mind controller, not to mention the skillful one. But, for the note this was not the first time Lou had a face off with a mind controller.
Yes, they were pain in the ass, but there was a way to take them down if you were careful enough.
Red light came chasing down Gedam when Lou started attacked him, it destroyed a stone when the light hit it. The damage was unthinkable if it really hit you.
But, Gedam was agile enough to dodge everything, he moved around and got two beasts to attack Lou, which made the merchant had to kill one of them and restrain the other. It was not a good feeling to kill your comrade, but then it was either he had to kill them or he was the one, who would be killed.
They danced in this fight for a while, until Lou had enough of it and put fire around him, trapped him in this circle of flames, which ready to burn him down.
