Final Fantasy V/The Water Crystal

Town of Walz
Once you have the dragon, fly south from Kerwin to the town of Walz. There are two islands, the west one has Walz castle and the east has the town. Land nearby and enter the town first.

Enter the inn near the entrance to rest for 20GP, the price has gone up but at this point 20GP is nominal. The item shop is here but it sells exactly the same things as in Kerwin. The weapon and armor shops are behind the inn. There is a new weapon, Battle Ax, but you don't have any jobs (other than Bare) which can equip it yet so you might as well come back for it later. The armor shop has Iron type armor that replaces the Bronze armor from Kerwin. To reach the magic shop, go east starting at the entrance of the inn and follow the path. It has new spells but for jobs you don't have yet, so come back for them later unless you have plenty of cash on hand. South of the magic shop, through a gap in the trees, there is a little girl playing with a Garula, a hint for thinge to come. There are stairs leading to the moat where you can talk to the frogs and access a private home on the left with treasure.

Some of the townspeople mention the king is using the Water crystal. So the next place to go is the castle to talk to the king. Exit the town, cross the bridge and enter the castle.

Walz Castle
Enter the castle, but before going in to speak to the king, take a bit of time to explore a bit. To the right is a double door and a stairway leading down. First go through the door with leads to the 2nd floor. From there is a stairway to the 3rd floor. Talk the scholars here for hints on things to come; press the switch on the floor to open the secret door. Back on the 2nd floor, follow the passage on the right and take the stair down to reach the Storehouse. As you might guess, there are goodies to find here if you search. The guard here as a big hint on something that will be covered later.

Go back to the anteroom and down the stairs to the 1st floor. There are actually four ways out of this room, but some of them are dangerous so proceed carefully. To the west is a stairway down to the dungeon. Two of the prisoners here will beg you to let them out if you talk to them; do not listen to them. In fact it's not a total disaster if you do; the one on the left gets so excited he knocks himself out, and the one on the right, who looks like a wolf, will cause an unpleasant surprise later on if he escapes. There is an urn inside his cell with nothing inside and if you go in to check the door closes behind you and you're trapped inside. Don't reset too quickly though as the door will open again after a few seconds. Back on the 1st floor, press the button on the floor to open a hidden door. This leads to the moat which is large but a dead end. The other two doors on the 1st floor, leading north and south from the east half of the room, are best left until later since they lead to tough battles.

Go back to the anteroom and up the carpeted stairs to start a cutscene. The King recognizes Reina and they greet each other. Note, this is the king of Walz, not the king of Tycoon who is Reina's dad. Reina asks the king to stop using the Water crystal, who is unwilling because the crystal is too important to Walz. The king starts rationalizing his decision, but just then the earth is struck by another meteor, similar to the one that landed near Tycoon. A soldier runs in and tells the king about the meteor and the king leaves to take charge of the situation. There is nothing more to do in the castle, unless you want to snoop around in the kings bedchamber, so exit.

The tower
When the king heads to the tower, it will be open for you; however, the meteor is still closed for now. Fly to the tower and enter.

The tower doesn't contain wondering monsters, but there are a few secrets. On the fourth floor, you can enter the water on the left and climb the vines to get a Silk Robe.

The fifth floor has a savepoint, before you encounter any monsters.

The eighth floor appears to be a dead-end, but had three climbable vines. The center is a dead-end path, The left leads to a silver ring, and the right leads to the next floor and an Ether.

The water crystal
Once you pass the ninth floor and enter the crystal room you will see Galura approach the crystal.

Galura has 1200 HP, and mainly uses physical attacks. From time to time, he will use the Rush attack to inflict extra damage and HP down status.

The crystal will shatter after Galura is defeated. You will be able to collect new jobs from the shards: Berserker, Mystic Knight, Red Mage, Summoner, and Time Mage. The Tower will begin to sink as soon as you collect the last reachable shard.

You will now be able to use the meteor to reach Karnak.

Worus Castle Items
There are a few items to collect within Worus castle, however, it is guarded by a dangerous monster. As such, you should save your game before entering, especially if you have low-level characters.

From the main castle forum before the throne room, head to the right and take the stairs down. Take the north-east exit and head down the stairs. Go down the path; you can head to the right to collect 2000 Gil and the Drag spell, and down the left path to get an Elf cape.
