I was finishing a zone today, and got my 5th ever Power Shot from a rare supply cache. And it made me realize that I have never gotten an ammo can from a supply cache. I know in Blood Brothers that you can get both Ghorns and Mandrakes from their chests. But here in FF, after 5 months of play I have not seen a single one. Even power shots seem exceedingly rare. Has anyone ever gotten an ammo can from a supply cache after finishing a map?
