I made a team of 5 female Ninjas (no Chantage/Ribbon, I don't like those things anymore, no challenge). Three have Steal, one has Elemental, and one has Math Skills and 80 Faith. The Math Skills are still good if the enemies have good Faith. I got that Calculator battle again, and the Math Ninja calc'd Haste and the enemy Calcs where owned badly yet again.
Unlike that Ninja battle at Araguay, they killed Orlandu once! Not completely killed, fortunately...
