Anyone who dared go into the Via Infinito without using Cat Nip naturally hit the brick wall of Chac. Without the right setups, she is impossible. I would've voted for her except Major Numerus is pure insanity. Remember how much HP you had when you played X-2? Well Numerus hits your entire party for 19000 damage after you've taken a maximum of two turns per character (and only if you're REALLY fast).
