What's this for? Wouldn't that be... *explodes*

So what is all the stuff you can loot in the game for? Not regular loot, of course, but all those things like Arcana, High Arcana, Soul of Thamasa and the like. I tried browsing some loot FAQ's , but they only told about how to get them, not what to do with them. Any help will be greatly appreciated! Linking to a guide is also OK! Thanks!

Second question: how do you use the bombs you can get at the Bazar? Do you need to have some particular weapon equipped? They don't seem to be related to the Hand Bombs license.

You use arcana and stuff for making items later in the game.

Just sell'em and they can open bazaar goods.

Bazaar - The Final Fantasy Wiki has more Final Fantasy information than Cid could research

bombs are used with hand bombs, like bows and arrows

Thanks Renmiri! It was just what I was looking for.
