Obtaining all of the Al Bhed Primers enables you to understand the Al Bhed language spoken by various characters in the game. Unlike in the previous Final Fantasy, each specific primer is not always obtained at a certain location. Since the game is not as linear as other Final Fantasies you may receive them at different locations each time you play.

On subsequent times through the game after you complete it the first time, you will not receive any Primers if you have already collected them all.

To start the PR Campaign, visit any of the game locations in the Calm Lands. Speak to one or the other representative and choose to help them promote their company.

You must speak to various people through out Spira, using the [square] button to either promote the company you're supporting or convince them to give the bachelor a chance (ladies only). The PR Campaign must be started in Chapter 1 or you will not be able to get enough points to get Episode Complete. The Bride sidequest is completely optional as it does not contribute to your story percentage or towards the Episode Complete for the Calm Lands.

In Chapter 5, if you have obtained at least 400 points for one of the rival companies, by beaming down to the Calm Lands, you will get Episode Complete! If you have not gotten enough points by then, you can earn more by playing the mini-games. Your reward is that all prizes for the company you worked for become available for purchase with your credits. This is the only way to obtain the Disaster in Bloom (Open Air) or Flash of Steel (Argent). Also a new mini-game and more transit stations will become available for your pleasure.

For completing There Goes the Bride, if you got 0-29 points, the father gives you an Elixir. If you got 30 or more points, he gives you a Speed Bracer.

After obtaining the Besaid Key, you can find another site of ciphers that will open up a new passage in the Besaid cave. Open the locked chest in the temple to obtain the Search Sphere which will allow you to discover the ciphers.

Once you go outside the temple a blue orb will appear in the lower right. If you hold the [Circle] button, a meter will show up beside it. It will start pulsing if you are close to finding a special commsphere. The stronger the pulse the closer you are. When it flashes red, hit [X] to dig up the commsphere. Hit [X] again to use the commsphere to search for the number.

1. Village, in the small area behind the shop - look at the roof of the temple
2. Village Slope, at the far left - look at the top of the ridge above the trees
3. Waterfall Way, just to the left of the first bridge - look under the 2nd waterfall
4. Valley, in the upper left corner - look at the lone palm tree across the water

Go to the Cave and head right. Enter the code you just found to open up the new passageway. You can now reach the chests that you couldn't get to before, particularly the one at the top of the ridge that holds the Raging Giant grid.

After speaking to Gippal at Djose and obtaining the Letter of Introduction you can go to Bikanel and dig for treasure. To begin a dig, speak to the hover pilot and choose a destination.

Digging procedure involves chasing down the white and yellow "X"s that appear on the screen. When you reach one press [X] to dig. The goal to dig up the yellow "X" and return to the hover before time runs out. The white "X"s may turn out to be items or a fiend encounter. You may also find up to 6 Al Bhed Primers to fill out your collection.

For each successful dig, you will receive some compensation gil. You can return to the Djose Temple and take an evaluation test. Each answer is worth 0, 1, or 2 points. Generally, you just answer as if digging were the most important thing in the world. If you pass the test, your wages will go up. If you fail, you must go back to Bikanel and dig some more before you're allowed to retake it.

You can also gain ranks that will grant you a new digging title, but they have no effect on the game. Your rank will raise after completing 15, 30, 60, 90, 120, 150, and 180 digs if you have more successful digs than unsuccessful at the time. There are 4 ranks: Sandbox League, Beach Comber, Sand Blaster and Zen Master of Digging.

If you are trying to get 100% story completion, then it is best to avoid digging too much until Chapter 5 (see Masterpiece Theatre).

In Kilika, there is a woman on the right side of the Dock that wants Squatter Monkeys. You'll need to search the woods to find enough monkeys for her.

While you are in the woods, listen for the monkeys' noises and when you hear them press [X] to search. Once you have found all 13 of them, return to the woman who will give you the Chaos Maelstrom grid.

The Thunder Plains Lightning Rod Towers are in need of calibration. In order to calibrate them, you will have to enter a series of commands in the form of button presses. You will be allowed 2 misses per try, upon the 3rd miss you will have to start over. In general, the southern towers are easier than the northern ones. There are 10 towers with 3 types to deal with: 3 for Rikku, 3 for Paine and 4 for Yuna.

Speak to the Al Bhed in the Travel Agency to check on your progress. Once you have attempted every tower and perfectly calibrated at least 5 of them, he'll give you the Samurai's Honor grid.

This sidequest is only available in Chapter 2 and Chapter 3. The prizes that are obtained in Chapter 5 during A Fallen Genius? are dependant on how well you do in this sidequest, so try to calibrate as much as you can.

The object is to pair up all the monkeys. For each monkey there is another with a name that "matches" in some way. Grab one of the monkeys and pair it with its match.

Once all monkeys have been paired up, you'll receive Soul of Thamasa.

In Guadosalam go to the Data Dealer (formerly the Inn) and speak to the man behind the counter. Ask "Got any data?" and then answer "Sounds good, I'll take it." to buy some bogus data for 10000. The Data Dealer will give you a clue about who to sell it to. You can ask him for more data and he'll give you a second clue if you like.

Approach the person you wish to sell the data to and press [square] to try and get them to buy. You get three tries to find the correct person, however the profit amount drops for every wrong person you try. You only get one shot at this, you cannot try again.

To start, you'll receive a set of 5 Reptile, 5 Bird, 5 Wasp and 5 Ahriman coins. Your goal is to win against 3 opponents without losing more than twice.

You can get the White Signet grid from the girl and dog sitting in the square, but only after you have 2 wins already. During the game, if one of the border coins has an Item attribute and you use it to get a Core Break, there's a good chance you'll obtain the grid. If you do manage to get it, deliberately lose the game so that you can save, otherwise you'll be catapulted into the final round immediately.

During the final round, you may get the Treasure Hunt grid if you manage to use an Item coin in a Core Break. If you win, you receive the Lady Luck dressphere.

If you do not win, you'll have another chance to win the dressphere later, but it will be much more difficult.

You must have collected all 10 of the Crimson Spheres to be able to unlock the door to the Den of Woe.

Ignore the side paths and follow the curving corridor forward until you reach the large square room. There, after a lengthy scene, Yuna must battle alone against Rikku then Paine. After those two battles, the girls will join together to take on Baralai then Gippal and finally, Nooj. There are no breaks between any of the battles.

Winning the battles nets you the Supreme Light grid and another Episode Complete!

Go forward to find Pacce and Hana and to find out a little more about this dungeon. Afterward pick up the Crimson Sphere 6 on the ground, select "I can't wait" to watch it now.

There are 100 more floors to this dungeon, with a boss on every 20th floor.

When you first enter, you'll find a chest with an S-Bomb and also get some instructions on how to navigate this dungeon. Weak walls need 5 S-Bombs (or 1 M-Bomb or L-Bomb) to destroy, medium walls need 5 M-Bombs (or 1 L-Bomb) and strong walls need 9 L-Bombs. You can check to see if a wall can be destroyed by standing next to it. If Yuna's skirt sways as if in a wind, the wall can be blasted.

After blasting through the first two walls (using 5 S-Bombs apiece), you'll come to a cross. Down the right corridor is a weak wall with an Epitaph behind it. Go forward and blast through 2 more weak walls to find a Mega Phoenix.

Go back to the cross and go left. Blast through one weak wall and turn right. On the left side, check for a weak wall that can be blasted. Behind it is a Black Tome.

Go back and forward again. Turn right at the fork (you can see some chests on the right, but ignore them for now). Check for a weak wall on the left that can be blasted. Go through and blast the weak wall in the center of the passageway to find a White Tome.

Go back and keep going right. Blast through a weak wall and then follow a jog to the left. Blast through a medium wall to find an Elixir.

Go back all the way to where you saw the chests. They're all empty, but you can blast the weak wall behind them. Go to the end and blast the weak wall on the left. Turn right to find yourself looking down a long hallway.

Check the right-hand wall for a medium wall to blast through. Blast through a weak wall at the end of the revealed tunnel to find a Elixir.

Back in the long hallway, a short ways forward there's a weak wall on the left. The chest behind it just contains fiends. A little ways further is a medium wall with a weak wall behind which is hiding another Epitaph.

Back to the hallway and just a few steps forward on the left is another weak wall. Behind it is a Mega Phoenix.

Continue further down the hallway and blast a medium wall on the left to find a Elixir. At the very end of the hallway, blast a weak wall on the right and another weak wall to find another Epitaph.

Backtrack a little down the hallway checking the right side for a medium wall. At the end of this passage is a strong wall. Blast through it to come to another 4-way cross. Before going forward, blast the weak wall on the right side before you reach the cross to find a Sword Tome. Blast the walls around this area to obtain gil or random items of which one may be a Bushido Tome or a Nature's Lore.

Turn left at the cross and then right. Blast through a weak wall to find a Turbo Ether. Go straight through the cross and blast a weak wall to find a Epitaph.

Turn right at the cross, go past a left-hand passage and take the next. Blast the weak wall there and continue on. Go forward, jump over a pit and blast a weak wall to face another Epitaph.

Backtrack and jump over the pit on the left. Blast the weak wall on the right for an Arcane Tome.

Jump across another pit and then blast through a weak wall then a strong wall. Behind it is King VERMIN!. Defeating it nets you the Font of Power grid and teleports you back outside.

The first time you enter, your primary goal is to find Cid. Follow the red arrow on the mini-map to locate him. When you find him, you'll have to defeat Machina Panzer. Your reward is an Al Bhed Primer and Episode Complete!

There's more to do in the cave: Still to do...

Once you have discovered the secret dungeon at the chocobo ranch, it will appear marked in green on the mini-map.

Take the first right as you enter to reach Turbo Ether x2. Take the first left to find Poison Fang x2.

Go back to the middle and go forward. Jump down and search for a hidden chest on the left with Wizard Bracelet. Go forward some more and take the next left. Continue until you come to a pit then turn left again. Jump down to find a Cat's Bell.

Now go back and jump across the pit. Just on the other side is Mana Spring x2. Go right from here and make another right. Jump down to the chest to get Mega Phoenix x2.

Keep going forward and then circle around to the right until you are back to where you jumped down to the chest. Don't jump down this time, but instead jump on the platforms to get to the ledge on the left. Go forward until you must turn right then jump up to the floating platform with the chest to get AP Egg.

Jump down and continue all the way forward then turn left. Jog to the right and continue on. Turn right and go forward. Jump down to find a chest with Stamina Spring x2.

Since you cannot go forward anymore, go back and retrace your steps until you come to where you jogged to the right. Go forward instead of right this time and follow the wall around until you can turn left. Jump across the pit here and then jump down to find a chest with Blessed Gem x2.

Climb up the other side and turn right. Jump across the pit and turn left to find a chest with Mega-Potion x2.

Go back across the pit and forward this time. Jump down where the next to last chest was and circle back around again. This time instead of jumping across the pit on the left, go right and then left. Jump across a very long pit. Turn left and jump down to get a chest with a Mythril Bangle.

Upon finding the amazing chocobo, you receive the Higher Power grid. Episode Complete!

In order to obtain the final garment grid: The End you must oversoul every enemy in the game that is capable of being oversouled. The game will keep track of which ones you have done in the fiend section when talking to Shinra on the Celcius. Once every blank has been filled, speak to Shinra to receive The End.

Each fiend that can be oversouled belongs to a certain type. After defeating a certain number of that type, the next one you meet will oversoul. As long as you do not defeat the oversoul fiend, the next fiend of that type that you meet will still oversoul. (Of course by not defeating the fiend, it means you've run away and thereby eliminated the incentive for obtaining this grid in the first place.)
