How do you get meteo? I rarely play the blm so never bother to look for it.
I think we need to get an ancient spell book in the late game. I cannot remember that book's name.
Take that book to an ancient library. That one house with 2 bridges close by.
The only one guy inside will ask you to choose only one spell between Meteo and Ultima for Oalston.
Meteo is a single target fire spell. With 2,000 Magic, it constantly deals 50k-60k to any bosses. Imagine hitting one weak to fire. lol
Ultima is an AoE non-elemental spell.
In my last save file, I got 19 before beating the game. :/ And I deleted that save file during the confusion of the gysahl green. lol
In my current game, I got 6 of them at the Nideen village where Leonardo asks us to retrieve Pandemonium from Gilgamesh.
Going forward, I will take note of where I found each one of them. It won't be quick as my job is quite demanding these days. ^^"
