Memoria can be accessed by traveling to the Iifa Tree, but there are some preparations that you may want to make before entering. For starters, equip your characters with any Wind-resistant equipment they may have as a primary means of defense for an upcoming fight. Secondary to Wind-resistance, focus on Water-resistant items and equipment.

Ribbons work very well as they absorb both Water and Wind Elem-Atk (and you should have three at this point if you have been following the strategy guide all the way through). Protect Rings also work fairly well as they reduce all elemental damage by 50%. Also make sure that Zidane has the Master Thief Ability equipped.

Fly the Invincible straight into the purple orb when you are ready to proceed.

There is a short cutscene at the entrance to Memoria where Zidane will speak to Garland. Choose your party members and then proceed up the steps towards the large castle.

Save your game and use a Tent at the strange looking multi-colored orb at the top of the steps. Search the right side of the screen for a hidden treasure chest that contains Kain’s Lance.

This is a fairly strong weapon for Freya but it is not stronger than Dragon’s Hair. Either way though, you may wish to equip is though so that Freya can learn the Dragon’s Crest and Cherry Blossom Abilities. Continue along the pathway and out the back of the room.

Stairs of Time

There is an invisible character called the Master Phantom on the left side of the entrance that you can interact with by pressing the or button and challenging him to a game of Tetra Master. Master Phantom has a number of high level Tetra Master cards that you can win by challenging him to a match. Follow the stairs around and into the next room.

Recollection

Follow the pathway up the stairs to the left. There is a small platform that extends outwards towards the screen. Examine near the edge of it until a Field Icon appears.

Open it to obtain The Tower which is a relatively strong weapon for Zidane but certainly not stronger than Ultima Weapon if you managed to obtain it during the Chocograph side quest.

There is a boss in the next area that you are about to face that has a number of Fire-based attacks. Equip items that absorb or resist Fire-based attacks such as Rosetta Ring and equip the Body Temp in order to prevent the Heat negative status effect.

Proceed to the next screen and along the Outer Path when you are ready and the boss battle will automatically initiate when you reach a certain point along the pathway.

Continue forward into the next room.

The Past

Move to the right side of the room and a cutscene will start once Zidane walks past the center pillar. The team will comment on how Memoria looks very similar to Alexandria and a short cinematic will take place as they observe out the window.

Walk up onto the platform at the end of the cutscene and inspect the right side to find a hidden Save/Tent point. Inspect the left side to obtain an Angel Flute for Eiko.

Oblivion / Recollection

Continue up the stairs and into the next area where Zidane will comment on the rain. There is another hidden Tetra Master player known as the Defense Phantom on the left side of the screen at the top of the stairs.

Proceed across the bridge and another short cutscene will take place involving Zidane and Dagger discussing one of her memories. Go up the stairs and into the next area.

Time Interval

The next area contains a large set of stairs leading up to an eye in the sky. Search the left side of the screen to find the Rune Claws hidden behind the pillar. The Rune Claws are Amarant’s Ultimate Weapon.

Equip your characters with equipment that protects against Fire-based damage similar to before and Wind-based damage as well in preparation for an upcoming boss fight and that they all have the Body Temp ability equipped.

Make sure that Zidane has the Master Thief ability equipped to help him Steal some valuable items. Climb the stairs when you are ready.

Ruins / Lost Memory / Familiar Past / World Fusion

Continue down the pathway through the ruins and into the next area (“Lost Memory”). There is another hidden card player here called Strong Phantom that you can challenge to a game of Tetra Master.

Go straight through the next room (with the bells) and follow the bridge up the left side of the screen. Another short cutscene will take place with Zidane observing Terra and Gaia smashing into one another. Follow the pathway into the castle on the far side of the screen.

Portal

There is another colored orb that you can use to save your game and heal your characters with using a Tent. Note that this is the furthest you can go while still intending to complete the Nero Family side quest. Click on the link for more information.

Continue forward in to the next area.

Birth / Ocean

There is an optional boss named Hades that you can find in this ocean area. Defeating it will reveal the Master Synthesist which you can then use to synthesize high level items for you.

Begin by equipping any Water absorbing or resistant equipment. Check out the Master Synthesist side quest section for more information:

You may wish to go back and save afterwards if you did battle and defeat Hades. Continue through the ocean room and into the next room for a short cutscene where the team discusses how Gaia used to be fully covered in water.

There is an upcoming boss fight at the top of the stairs. You should prepare by equipping each of your characters with armor and accessories that absorb or resist Water-based magic attacks. The Ribbon accessory works exceptionally well here again with the Protect Ring working as a half decent substitute for those not equipped with a Ribbon.

Equip each of your characters with the Body Temp and Bright Eyes Abilities if they have them and then continue up the stairs.

Continue up the stairs and enter the next area.

Time Warp

This room has a large broken clock with a pathway leading around it. At the bottom of the stairs on the right side of the screen is a hidden Save Point / Tent Point that you can access.

There is also another hidden Rare Phantom at the top of the stairs in the area towards the back of the screen. You can challenge “the ghost of Card Master Empress…” to a game of Tetra Master to win some rare cards. Proceed west into the next room when you are ready.

Gaia’s Birth

Enter the large room and another short cutscene will take place showing the birth of Gaia. Climb the ladder up and into the next area. Search the left side of the platform to find the Mace of Zeus. This is Vivi’s strongest weapon which can teach him the Doomsday spell.

There is another Dark Phantom on the right side of the platform that you can challenge to a game of Tetra Master if you wish. Some preparation is required before you proceed up the ladder towards the next boss fight.

The next boss will cast a spell called LV5 Death which will instantly kill any character who is currently a level divisible by 5. You may want to engage in a couple more battles in order to level your characters until they are a level that is not divisible by 5, especially if you have more than 1 character who would be impacted by the LV5 Death spell.

Equip each of your characters with the Antibody and Locomotion Abilities and equip your characters with equipment and accessories that can either absorb or resist Earth-based attacks. Feather Boots, Circlets and Gaia Gear work extremely well.

Climb up the second ladder and go through the door at the top. Walk towards the doorways to initiate the next fight.

Gate to Space

The game continues in a large room with some archways in space. Search the left side of the room to find a hidden Save/Tent space. This is also where you would obtain Excalibur II if you managed to complete that side quest.

Go through the gateway and into the next room when you are ready. There is another short cutscene before you reach the final area of the game.
