couple questions:
after final BC, if you want to fight again, do you need to do all 6 other fights again first?
No one knows, you can't re-accept the quest (yet).
if so, after final BC, can you enter to help someone else even if you completed the fight, even if you haven't fought the other avatars again yourself?
Haven't tried.
do carby cuffs have hidden effect -perpetuation for carby?
does carby pole have hidden effect -perpetuation for carby?
Only the pole is offered as a reward, and it has no hidden effects.
if you do the final BC and don't accept reward, and do it again, is it confirmed that you get cuffs, or still just a rumor?
There is no way to refuse a reward. Choosing "Not at this time..." just results in a different title and dialogue, but you still get the Faded Ruby key item, and still get the Pole when you talk to Carbuncle (no choice offered to refuse a reward).
is the time limit on repeating final BC daily, or weekly, or no time limit?
If you can repeat it, it'd be weekly, because no one has been able to re-accept the quest yet.
thanks
