Sunken Shrine
This dungeon spans five floors with 32 treasure chests scattered everywhere. You'll arrive on the third floor. Thunder-based magic is essential here; most enemies are vulnerable to electricity, so Thundara and Thundaga will clear encounters quickly. Check the bestiary for full enemy weaknesses.
Sunken Shrine Directions
3F. Start by exploring the small room on the east side (connected to the large C-shaped room) and the west room for their chests. There are two staircases on this floor. Take the stairs in the northeastern area first; they lead to the treasure-filled upper floors.
4F. Walk south, take the first left, then south again, left again, go up and take the first right into a room with a chest containing 1,300 Gil. Exit the room, go north, take a left and follow the path north in a zigzag pattern. The room at the top has Diamond Armor. Exit and go down the zigzag but take a left this time, following the path south to the bottom of the map. The room here contains a Light Axe. Exit, go right, and at the fork you'll see a room to the north containing a Mage's Staff. Go south at the fork this time and continue heading right until you reach a room with 12,350 Gil. Exit and take the stairs on the right up to 5F.
5F. As soon as you enter, go into the room directly north and open the three chests. Exit, go north and take a left. Follow the path around until the intersection and go north. This path takes you westbound to the other side of the map. Take the first path down and you'll come across a room with three chests. The one on the far right contains the Rosetta Stone, the key item you came here for.
This floor has mermaids who share lore about the crystals and Mirage Tower. Open your map and visit all the remaining treasure rooms around the edges; they contain Diamond Shield, Diamond Helm, Diamond Gloves, Diamond Armlet, and plenty of Gil. The full Diamond set gives your Knight excellent defense. Once you've collected everything, head back downstairs to 4F and go northeast to take the stairs back down to 3F.
Lower Depths
3F. Head south, left (skip the southern route with the pillars), and take the second southern path. Take a left and in this room you'll find a chest with 9,900 Gil. Exit the room and go north, take a left and north again to the stairs that take you to 2F.
2F. Walk north along the damaged walkway until you hit a wall. Take a right and go north again up the stairs. Continue until you reach 4F. Go around the room and take the stairs down to 3F. Open the door and collect both chests. Exit the room and take the stairs down to 2F.
Take the first southern path and there's a room with two chests; the left one contains monsters. Exit and head west until you reach a room with three chests, two of which contain monsters. Exit and take the second path going north. Take a right at the wall, go north through the pillars, and there's a room with four chests and an enemy. One of these contains a Ribbon. Exit the room and go far west to find a room with a second Light Axe. Key treasure on this floor: Giant's Gloves (casts Saber when used as an item) from the southwest room. Head east and north until you hit a wall, then take a left to the stairs leading down to 1F.
1F. Go north and follow the path through the door and out again. Go to the wall on the far west and follow the path. Enter the room and continue going north. Take the first left, walk south through the door, then north until you reach the Water Crystal chamber.
Kraken
The Fiend of Water guards the crystal. Kraken only uses physical attacks but gets eight of them per turn, so the damage adds up fast.
Defeat Kraken and the Water Crystal is restored. Use the portal to exit the Sunken Shrine.
