Bahamut Lagoon - Quick Walkthrough

Chapter 9
Mahal, the Continent of Miracles
The Resistance is headed for another lagoon that was taken over by the Empire - Mahal. Taicho used to be the captain of the army of Mahal, but thanks to Lestat, that's all old history. Now it's time to give Lestat what's been coming to him.

After seeing a flashback sequence, you'll find yourself outside, standing in the rain. Do your normal dragon feeding stuff now.

Talk to Truce. He'll let you see a plan he's been working on. The plan is to open the floodgate upstream of where Lestat's forces will be and then let the flood of water take them out.

You're gonna need to get to the floodgate as quickly as possible, or the flood plan will be virtually useless. Unfortunately it's quite a bit away from your starting position. So for this scenario, it's a good idea to put 3 black magic users who can use Thunder Gale and Lukia in a party. Lukia is a Light Armor knight, so she can move a lot quicker around the map. Having her in the party lets that party move around faster. See, it pays to change your formation intelligently.

There are three enemy parties guarding the floodgate. Have most of your dragons on the "Go" command. That way a couple of these parties in your way will get wiped out. When you get to the floodgate, try standing in the same position as in this pic, and use Thunder Gale on the spot where you're standing. It's hard to get the dam to break but this seems to be the most reliable way of doing it.

Once you've done this, head for Lestat ASAP. There are probably still lots of enemies around him. Take them on if you can - they should be quite low on HP. Otherwise go straight for Lestat, and watch out for his petrification and poison attacks.
