FInal Fantasy VI Advance N-S-C-W! TonberrIES

Abilities, Stats and actual battle in-video. There is Tonberry in the same cave, but he acts differently (Uses Traveler and Knife as counter attacks). That's why I told you not to be mistaken. Since they do NOT use Traveler, Phantom is the way to go. After that, anything but Magic command will work. See? You are completely invincible. Unless you USE Magic, which will make them use Holy.
