Seems like RamsHead has it more or less nailed down with the exception of Niefelhiem winning.
Seriously, high level evocation or not, I'm kinda doubting anyone can stand up to Helhiem. I haven't fought anything but their PD so far, but from what everyone says about them (in the main board about them being overpowered, not here), things are grim. I just have to find out how much 10 thunderstrikes can do to their forces.
