What Shy said, Beth saw James unwittingly restraining himself by impaling Iava with his spikes, then she decided to capitalize on that by freezing his hands so he can't pull those spikes out of Iava's body for a brief moment, practically shackling him in place.

I think he'd eventually tire himself out since casting spells exhausts you just as any other strenous activities would.
