Ok. That is a lot closer to what my understanding of how the Prizes worked. Because I missed the Magic Comb once and I was confused and Pissed Off! The whole thing seems further complicated by the fact that sometimes you get "Tincture" and "Potions" that never appear in your inventory (or maybe the Tincture gives you an Ether or something) and there are series of battles that are impossible to be at Fort Condor for! Bottom line seems to be, if you want a certain item, make sure you're fighting the battles yourself at the appropriate times/sequences.
Its funny...they can drop to 0 gil and apparently fight battle after battle yet Fort Condor still stands! Should have the option of permitting Fort Condor to be completely obliterated if you offer no physical, tactical, or monetary assistance. For me, I just need that Magic Comb at the beginning, the Super Ball mid-game, the Imperial Guard off the Commander in last battle, and the Phoenix. Oh and Huge materia too...which huge is at Fort Condor anyway? The Green one?
