Alexandria

Steiner and Marcus are trapped in a suspended cage. Move it back and forth until it hits the railing on the right and you can escape. Now run to the left side of the balcony and climb the ladder and go left.

You’ll now have ½ hour to rescue Dagger, but dialogue takes up a lot of that time. After the conversation with Marcus go down, left, and then run up the courtyard to the main castle all while avoiding the guards.

Run up the stairs and go out the far center exit and up the stairs here. At the top go left through the double doors and through to another set of doors at the back.

Examine the purple glowing candle on the back wall and try to move it. Go through the secret opening. Here you’ll have to hop onto the rotating slab and jump off on the other side. The two chests contain an Ice Brand and a Tent. Once across run all the way down the stairs and enter the door at the top of the area.

During this battle there will be notifications that one of the two twins has been given “Meteor Power” or "Flare Power." Make sure to attack this twin physically to stop the attack. Other than that, steal with Zidane and have Vivi use Blizzara. Keep in mind that if you kill one twin the other is defeated too.

After the battle you can save with Mosh the moogle. Then head back upstairs. Back in the Queen’s room you’ll have one final battle with Beatrix.

Once again Beatrix will finish this battle with one of her powerful attacks (Climhazzard this time) so use Vivi’s Slow spell to buy yourself more time for stealing. Use Vivi’s Blizzara and Steiner’s Blizzara sword to attack.

After Beatrix sees the error of her ways Brahne will turn on her and unleash Bandersnatches on the group. After the battles you’ll get control of Zidane again and you’ll need to run back to the bottom fighting Bandersnatches and Black Mages along the way. At the bottom head back into the chapel and pick up a letter from Mosh to Monty. You might also want to save. Now go out the bottom exit. You’ll get caught briefly, but saved by Blank and Marcus. Go down and board the gargant.

This time round the serpent has learned some new spells and tricks. Have Dagger Shell and Protect as needed. When the serpent is coiled up you can’t physically hurt it so only use magic. Have Zidane steal every round and once you’ve got everything have Vivi Blizzara it until it runs off again. The worm also has an attack that will cast Mini on your characters, which lowers your attack and defense. While you're stealing this doesn't really matter. The only way you have to remove mini is if the boss casts it twice on the same person or by using remedies - don't use your remedies unless you're ready to kill the boss. Also, it seemed like Shell sometimes protected against Mini so it might be worth keeping on the party.

Once you’re back in the gargant carriage the serpent gets back up and chases you until the gargant crashes at Pinnacle Rocks.
