He beat the brutes while also tampering with the spell towers' efforts to cast spells. He would rip apart her spell matrixes before they formed by using his own divine sense to disrupt their connection with the law matrix. They have about the same spiritual power but she is the one that needs order to cast the spells. All he has to do is sow discord and Chaos. That is easy to do because destruction is easier than creation.
Again, that's the best he can do to her. The immortal link will redistribute the threads and boost the spell tower so that she can form more shields if he tries to do more. It is frustrating him to no end. He isn't fighting 3 paragons. He is fighting 4 of them at once and he can't do anything to hinder the 4th one.
