thanks for the full revival tip. Great, you beat the robot.
as for FATE, he/she was pretty easy for me (they said FATE is female, but during battle it says FATE'S male). anyway, since FATE casts Diminish right away, that will half all element damage, so go for physical attacks. Occassionally cast a few non-black elements to keep from letting FATE turn teh field black. She will use her countdown attack, and when she reaches zero, she will use...was it DarkEnergy? i dont remember, but keep your health up when she gets close to zero. i recommend using only white elements, and green (since green is the number 2 healing color).
and by the way, i used Fargo to steal from FATE, and he stole a HolyHealing, which heals your whole party by about 600-700. It's a level 6 element that can be put at least to level 4.
