I forget specifically, I was certainly using fire storm when i could - by the stage of my devils getting decimated i was fairly chewed up, earlier on my armies of devils + infantry + fire evocs did very well against Pangaean hordes.

Fire storm generally isn't effective quickly enough to save that situation though, the devils get chewed up very fast late game with storm. If I still had a decent earth caster with my army at the time i should have tried some earthquaking, i forget exactly when my father illearth died
