Final Fantasy V/Water Lithograph

Easterly Falls
Take the airship to the northwest corner of the world map, submerge, then pilot to the point of interest on the north side of the large bay in the western continent. When you reach a glowing cave, the ship docks itself; exit the sub and go through a small cave to a desert area. Follow the desert northwest until you reach Easterly Falls. Continue into the falls to find an small cave with the two usual guardians. Defeat them as before, and approach the door to have a page of the book open the door as before.

You enter a large room with ledges and waterfalls. There are stairs scattered around for you get to the higher ledges. One monster to look out for here is Dinglberry. It slowly approaches your party without doing anything, but when it gets close enough it will attack three times with enough strength to K.O. one of your characters with each blow. Cast Blink to avoid these attacks since the monster has a high enough HP that you probably wont be able to defeat it in the short time it takes to reach you. Another monster to watch out for is Alcumia, similar to Zefa Zone in the Pyramids only this time she changes a toad into a monster to fight for her.

Go up the center and ride down the falls on the right to grab some treasure on the way. Now go to the left side and get the treasure there. Go back, up the center again and exit at the top. This takes you to a small area with two exits; take the one on the right first to B. 2 Floor.

Wade south then up to a ledge for treasure. Continue to the southeast corner and follow the dark tunnel to another chest. Follow the ledge west to the other side of the room; the pool here is where you land if you take the left exit in the previous room. There is chest on the north ledge here. To get it, change a character to Thief, or equip the Dash ability. Now press the button on the left side of the ledge to stop the flow of water blocking the way, then Dash over to the right and open the chest before the water starts again. Exit in the southwest corner to B. 3 Floor.

Follow the path over the water. Get treasure at two dead ends, then exit south to a room with a save point. From here it's a good idea to have a Geomancer or equip one of your characters with the Findhole ability. Continue to B. 4 Floor. Get the treasure in the small room in the center. Exit the small room and circle to the west of it, avoiding the trap door near the start of a passage leading north. Exit in the northwest corner to a small ledge on the previous floor with treasure. Go back to the the B. 4 Floor and get the treasure in the southwext corner, then exit south to B. 5 Floor.

There are buttons here which don't do anything but make crystals pop out of the floor and disappear again. Grab the other chests in the room, then press the button near the chest in the southwest corner to reveal two holes and reach that chest. Get the final treasure and drop down the hole.

Circle to the north, the get the lithograph in the center of the room. When you attempt to leave with the lithograph one of the monsters from the N-zone appears and orders you stop. He calls forth the monster Leviathan to stop you. Leviathan defeats the monster that summoned it, which is nice, and it's now time to defeat Leviathan. But not necessarily; if you want you can just exit the room without fighting so this battle is optional, even if you get the lithograph. But assuming you don't chicken out, check the monster to begin the battle.

When the battle is over you get Leviathan as a Summon spell. Exit the dungeon using Telepo or by sliding down the waterfall to the south.
