Don't crucify me for going pre-VII on you all, but VI introduced the Limit Break, and they were the best. Sure they are not 15 critical hits and all that jazz, but if you kept a person in near fatal status long enough to pull one off, you do something like 3K damage. At Level 8. Sorry everyone, but Terra's Riot Blade is my favorite. Freakish damage and unblockable poison...like Kefka says."W00T W00T W00T w00t w00t...".^.^
But yeah, Climhazzard is awesome too. The first time I saw it, it was on a land worm. Nothing beats stabbing something with a HUGE sword/pillar and dissecting it.
