The Last Story/Reptids' Cave

Reunite with Zael
Welcome to Lazulis Island. The game begins with you in control of Dagran, a close-range fighter, and with Syrenne, a fighter who wields two swords, in your party. Press to open the tutorial on movement and the camera (use  to move,  to move the camera, and  to reset the camera). Follow Syrenne through the cave. Time for your first taste of battle. Simply approach enemies to attack automatically (you can change this in Options to attack with instead). The Reptids here are fairly weak, though they'll try to run before you can get them. Give chase. Further up the cave system, a pillar will crumble, and you'll be shown a tutorial on hiding (press near an obstacle to hide behind it, and press  again while hiding to emerge) and vaulting (while hiding, hold  and press ; while moving, hold  while moving to vault automatically). Finish the enemies, and return to where Syrenne is. After a cutscene, a new tutorial will explain the battle system, guarding (hold ), and lock-on (press while guarding). Despite your best efforts, the Reptids will simply keep calling in reinforcements. After defeating a few waves of Reptids, control switches to Zael and Yurick.

Zael and Yurick are in a separate branch of the caves. Head straight ahead from where you start. Here, some Reptids are waiting ahead. They haven't seen you yet, giving you a chance to get the first strike. Hold to enter Seek Mode, and use  to look around. Look at one of the white targets, and tell Yurick to "Destroy it!". Yurick will throw some Fire magic at it, destroying the pillars in the area, and taking several Reptids with them. Finish off any that survive, and follow Yurick towards the source of the Reptids' horn. Follow the caves to find Dagran and Syrenne surrounded by Reptids. Look at the bridge above them, and have Yurick destroy it, while you go out and help Dagran and Syrenne take out the Reptids on the ground. With them all defeated, a massive Reptid Gladiator will smash through the wall, with several smaller Reptids. Protect Yurick from the smaller ones until he can get a shot in on the Gladiator, who is weak to Yurick's fire magic. Once Yurick can get a spell out, the Gladiator should be easily defeated, as Yurick's fire magic will spread to your weapon if you enter his fire Magic Circle.

Ambush the Reptids
After the cutscene, follow the rest of your party through the caves. Just after where they stop is a Save Point. Save your game here, and head further on. This area contains more Reptids, some of whom can use magic. You are to attack them from the right, while the others will attack from the front when you give the signal. Use the preparation screen to plan your ambush, and press when you're ready to engage battle. Head to the right as planned, where you receive a new tutorial on Zael's crossbow (use Seek Mode to aim, press to shoot, and use  to select arrow type). Head up the right, and up the spiral staircase to reach the Reptids. Slowly move around until you have a clear shot at either the mage or the healer, and kill them with a Wizard Slayer arrow. This also gives the signal to your allies, who will join the fight to help clear out the swordsmen. After all are defeated, stand over the triangular object in the centre, and press to move it. This causes some of the ceiling to collapse, creating a bridge. Cross it, and follow the caves to an apparent dead end. Press when prompted to kick the wall down, and enter.

Gathering
Look around the ruins a bit, and follow the others when they move. Dagran and Yurick will leave to look for an exit. After a conversation with Syrenne, the skeletons in the area will rise and begin attacking. Fight back. After fighting off a few of the skeletons, a secret path will open. Ignore the skeletons and run down the new path. At the end, check the altar-like structure on the back wall, and the square on the wall to the left. After these routes prove useless, a skeleton will attack Syrenne with an arrow, downing her. After a cutscene, you receive the power of Gathering, which draws the attention of your enemies to you, and away from your allies. Use it by pressing. The following tutorial will also explain your new Cure ability, which allows you to revive downed allies by walking near them while Gathering is active. Walk over to Syrenne to revive her, after which Dagran and Yurick return. Defeat the skeletons, and the door that was "sealed by the curse of the undead" will open.

Follow yet more caves to a chasm with a bridge crossing it. Step onto the bridge, and more skeletons will attack. Activate Gathering, then look at one of the broken bridges to the left and right, and have Yurick destroy it. Knock the skeletons off the bridge to defeat them. When Yurick informs you of reinforcements, have him destroy another broken bridge to your left or right. When all are down, cross the bridge to the door where your allies move to. To the right is a red circle called a Summon Circle; use Gathering while standing inside it to summon more enemies. Use this if you want to do some level grinding. When you're ready, go back to the save point across the bridge and save, open the door, head up the stairs, and enter the next door.

Boss: Cocoon
The Cocoon, as you might have guessed from its size, isn't going to go down in a conventional battle. As soon as the battle starts, you're given a tutorial on diving (press or  while moving), which is crucial to surviving this battle. Take aim at the Cocoon's head in Seek Mode, and have Yurick attack it with magic. Use Gathering to take its attention away from Yurick while he's casting. if you start running low on health, pick up a white bomb with or, and throw it to release a circle of healing magic. Walk through the circle (you don't need to remain in it) to begin recovering HP. Soon, some skeletons will join the battle. Keep them off Yurick's back while he's casting. Eventually the door will open, allowing you to lure the Cocoon to the bridge. Lure it out with Gathering, and run for the bridge. The Cocoon should follow. Outside, Yurick will destroy the bridge when the Cocoon tries to cross it, causing it to fall into the chasm to its death.
