Black Mage Unlocked!
I took THM to 30 and along the way learned Swiftcast for my White Mage. Now I can Raise other players instantly, a very handy skill indeed!
I would have stopped at 26 when I got Swiftcast, but I really wanted to know how the guild's story ended. The Black Mage one seems pretty exciting too, maybe I'll pick it up again some day!
