The chest inside this hidden enclave contains another Ribbon accessory. Exit the secret enclave and head north to the next chest. It contains a Javelin for Cid. Make your way into the open doorway to the right at the north end of the screen.
Follow this pathway under the ice pathway and to the top of the hill inside the cave. At the top you will notice a small round boulder perched over the edge of the cliff. Walk over to it and give it a push. The rock will begin rolling down the pathway clearing a trail for you. Go back down to the ledge and work your way up the newly cleared pathway. Follow the pathway around and into the next room. This should put you back outside the mountain for more rock climbing.
The next cave starts you off in a large room. There’s a save point at the northern end. Go through the door at the top right side of the screen. It’ll lead you on a long looping pathway around the outside of the mountain.
In the next room there will be a chest on the right hand side containing a Fire Armlet. Make your way from the right side of the screen to the left along the platform, and each time you encounter an icicle you will have to fight it. Each time you defeat one you will be asked if you’d like to jump down choose no every time and work your way across to the other side.
The chest on the left gives you a Megalixir despite telling you that you get a “Last Elixir”. Walk back to the right side of the platform, near the chest you opened earlier, and you’ll be prompted to jump down to the lower platform. Choose “yes”.
You can now open the chest near the save point. The last icicle cleared the pathway for you. It contains a Speed Source. Save before making your way up the new path laid by the icicles. This time make your way around the left side of the mountain. The chest just in front of you contains the Enhance Sword. It’s a really nice weapon if you have a lot of Materia to equip, but if you are like me and like to use standard attacks, this probably isn’t the best sword for you considering it has a lower attack power than Organics. Follow the pathway to the outside of the mountain and start working your way up the mountain once more.
Save at the save point, there’s a boss in the next hallway that you should do some preparing for.
