Here are the results from the final four:

1. Black Mage (Vivi) - 6
4. White Mage / Summoner (Eiko) - 4
In the battle of the pint sized, Eiko summoned Carbuncle for reflect effect. Unfortunately she forgot she had a Diamond equipped and it did vanish instead. Not the best status to have when Vivi is powering up a death spell...

2. Thief (Zidane) - 8
3. Knight / Sword Mage (Steiner) - 2
Zidane tried to steal Steiner's armor but missed. Steiner then hit him with a powerful shock attack, sending Zidane into trance mode. Unfortunately for Steiner he didn't have any more mp to use Shock again, so he went for a regular attack. Trance Zidane laughed at this puny attempt and took him out with a few Dyne moves.

Final match:

1. Black Mage (Vivi) vs. 2. Thief (Zidane)
