If you choose Equipment menu you will see some different types of missiles.  But if you hold triangle and square and up, you will see Galbadian Elite Soldier doing a weird dance!  But that's not all!  If you hold down instead of up, you will see a normal soldier doing another weird dance!!  Great stuff, er?

Autopilot Function

Did you know the Ragnarok has an Autopilot function?  If you're in the Ragnarok and use the full size map and choose a city, the Ragnarok will be CPU controlled and go to the city.  No more hassles or steering problems.

Mod-Win-Back-Card trick
This only works in disk 4, provided you have finished the CC Group mini-quest in previous disks.  In the Ragnarok, mod any card you wish.  After modding, challenge a CC Group member to a game of cards.  Sooner of later the player will have the modded card in their deck.  Win the card back, and you will still keep the items you have modded earlier (easy to get 100 Holy Wars with the Gilgamesh card!).  Note that this might not work with the Pupu card or the ones you picked up during the Queen of Cards Quest.

Free Rosetta Stones

Esthar - If you visit Cheryl's store during the Lunatic Pandora Event in Esthar when you control Zell, you will recieve a Rosetta Stone as a present.

Ultimecia's Castle - Play the large organ in the chapel, room north of the fountain.  Play all the keys at once to reveal another Rosetta Stone.

Free items in Dollet

In Dollet, in the area where the hotel and the fountain is, examine the dog on the right-hand side and Squall will find a bone.  Inspect it and you will recieve a X-Potion.  Now go to the Card Queen's house (One scene down from the pub).  Her father will complain about the boy drawing a bone on his painting.  Examine the painting.  Now go to that area and you will find the dog and the bone.  Now you get an Elixir!  Repeat the process again, except in the different area.  Your last item is a Megalixir.

Fountain - X-Potion
Pub area - Elixir
Outside Card Queen's House - Megalixir

Good amount of EXP & AP

For a good amount of EXP, visit the Islands closest to Heaven and Hell (See World Map) and you will find monsters Level 100!  By defeating them, you could get heaps of EXP up to 2500!  Having Odin is handy too.  Also, you can find Draw Points of good spells on these islands.  They are hidden, but junction Diablos Enc-None and run around the coastal areas, pressing X.

For a good amount of AP, visit Cactus Island (See World Map).  The Cactuars who live gives you 20 AP each!  In one battle you could receive up to 80 AP!  You'll learn those 250 AP Abilities in no time!  Note that the Cactuars are very afraid of you and can run away easily, so use water spells and  physical attacks if your characters have high hit rate. 

Queen of Cards in Disk 4

The Queen of Cards in Disk 4 is on the tip of the Southern Esthar Peninsula.  You can't see her normally, but if you walk on the right place you will be automatically transferred to her.

Finding the Ragnarok in Disk 4

From Ultimecia's castle, enter the portal closest to the castle and you will be transported to Grandidi Forest Beach.  Look for the large Chocobo Forest deep in the forest and get the chocobo. 

Go south through the narrow area through the mountains.  Then go to the nearby beach and travel through the shallow water to the beach near Edea's House. Then travel East from Edea's house and go  through the small strip of flat land. 

You should arrive at the Kashkabald Desert.  Look on the World Map for a Red Dot and go towards it.  There, you can go back in the Ragnarok, and surprise, surprise!  The CC Card Group are now in the air ship, once again challenging you to card games. (Note: If you didn't finish the CC Group sub Quest, the card players won't be on the Ragnarok.)

Finding an Elnoyle easy

In Esthar city, go to the middle part of the city, where a path goes right  (with steps) on the screen from the main path, south of the Presidental Residence.  A little dark man is leaning over.  Talk to him, and he'll laugh, and he transforms into a Elnoyle.  Once you beat him, walk away, and come back to the screen.  He is once more alive, back to its original place.
