Final Fantasy: Special Rule for Ballista

Special Rule
-------------
Previously, Ballista has used a single victory per series system. Now, each series will use a "best two of three" system. One match will take seven Vana'diel hours (19 minutes Earth time), and there will be a 1.5 Vana'diel hour (four minutes Earth time) intermission between matches. See the following table for a complete match schedule.

1st match 7 hours
Intermission 1.5 hours
2nd match 7 hours
Intermission 1.5 hours
3rd match 7 hours

In the event that each team wins one of the first two matches, whichever team wins the third match shall be the winner of that series.

However, if the same team wins the first and second matches, the following condition shall also apply: A team that wins the third match and has the top-scoring player shall be awarded two match points. This means that it is possible to force a draw even if your team loses the first two matches.

You can confirm this rule by talking to a Pursuivant. Be sure to confirm the entry period as well as allegiance and level restrictions before entering.
