* CK, feel free to toss out the Divine Weapon if you want. I know some people assume Accelerator is just an action that can be used and the boss AI is super-stupid and thus DW is unbeatable given a turn, but I definitely think that there's no in-game difference between "random chance of activating" and "random chance of the AI using the move." FF6 enemy AI will pick "Critical" 20% of the time and "Fight" 80% of the time for some scripts, for example, but clearly it's not really an AI choice; it's implementing a percentage activation via AI script. And we don't even know if it's an AI script issue or not in WA4 anyway. Go with Violetta (G3) if you toss DW.
