Final Fantasy Tactics - Apoplexy 2 (Not on OST)
There are a few other versions of this hard-to-find track on YouTube, but I uploaded anyway because:
1 - This version is a minute longer than others.
2 - None of the other versions have very many views. As one of my favorite tracks from this game, I wanted to help spread the love.
3 - It has a white mage slideshow. White mage slideshows make everything better.
Pictures can all be found on various boorus, except the one at 1:50 where the white mage has a Protect spell up - that's from DeviantArt.
