Thunder Plains: Dungeon Raid

Begin by noting the information in the top-left ("No Data") and bottom-right ("\_\_ -> ##") of the screen. This information is crucial for unlocking walls.

Press Square to review this information up to three times between unlocking walls. The top-left displays the current wall number, and the bottom-right displays the next wall number. Note these down every time.

When examining a wall to open, input a number that is the sum of the current and previous wall numbers you noted.

After opening a wall, two chests will appear. One contains a clue, and the other is empty.

Examine the initial message seen upon entering the cave by pressing Square. This serves as an explanation by example.

The number in the bottom-right is the "next wall" number. The key number is six, and the wall number is 3.

The map in the top-left shows your next number. Yuna will automatically head to Wall 3, but you must learn to navigate yourself.

Examine the wall with X.

The second number in the top-left corner is the first Key Number for Wall 3. (2 in this example.) The second Key Number for Wall 3 was 6. The input is 2 + 6 = 8.

After proceeding, note that the Key Number in the lower-right changes (here, to 20 for Wall 10). Record this.

Open the chests that appear.

Wall 3: This should have been completed during the tutorial. The numbers are random but derived from previous walls' clues.

Wall 10: Go south from Wall 3, then along the path. Go west and north at the intersections; it will be on the west side. Before going north, go west for Diamond Gloves. The numbers are random but derived from previous walls' clues.

Wall 11: Grab the Hyper Wrist in front of you, then go south. Grab the Battle Compendium to the west at the intersection, then go far east for the Code Compendium. Go north and east at the intersection for a Mystery Veil, then west to the door. The numbers are two random ones.

Wall 5: Go south, then east for a Talisman. Go west past the two-way, then north to the wall. One number is random, and one number was previously used.

Wall 1: Go west and you will find it. One number was previously used. The second was the number of battles fought between entering the cave and opening any walls (0 with a Charm Bangle).

Wall 8: Go south from Wall 1 to a two-way. Go east, then south, then west and along the path to find a Nature’s Lore. Return to the intersection south of Wall 1 and go west, then south, then east to find it. The first number is an already-used number plus the number of battles since entering the cave. The second number is random.

Wall 12: Go due south from Wall 8 and head east at the second intersection; it will appear to the south. The first number is random. The second is the sum of two old numbers.

Wall 13: Go east in the hall after Wall 12; it will appear to the north. Both numbers are random.

Wall 9: Go east from Wall 13 in the hall north of it, then go north for a while when first possible. The first number is an old number. The second is the number of battles fought between this wall and Wall 12.

Wall 6: Go west and north. The first number is an old number plus a random number. The second is the sum of two old numbers.

Wall 7: Go east a bit. Grabbing the Gil Compendium is recommended. The first number is the amount of Gil earned since entering the cave (0 with a Charm Bangle). The second is the sum of an old number and the battles fought since opening a wall.

Wall 14: Go west, south, and east from Wall 7 to find the Corpus Invictus. This wall is in the south-central portion of the area, between where Wall 12 and Wall 13 were. The first number is an old number, and the second is the sum of two old numbers.

Wall 2: East of where Wall 1 was. The first number is the number of battles fought between opening this and the last wall. The second number is random.

Wall 15: Head north from where Wall 14 was. The first number is the sum of two random numbers given plus the Gil earned since the last wall. The second is the sum of an old number, the battles fought since the last wall, and the Gil earned since entering the cave.

Wall 16: Keep going north. Grab the Salvation Promised Garment Grid on the way. The numbers are two random ones.
