Gi Cave
Item:
"Added Effect" Materia, Black M-phone, Ether, Fairy Ring, X-Potion, Turbo Ether, "Gravity" Materia
Note:
You may want to equip your characters with items that prevent death. Most creatures in the Gi Cave can cast Death Sentence.
There are lots of holes. In the walls of the first cave and inside each is a rock. Breaking a rock normally starts a fight, but one opens a secret door. Check the map for its exact location.
The next area is a small maze composed of several twisting paths. Walk down the stairs to collect several items or take the path on the bottom left to get the "Added Effect" Materia (you may remember this from the first map).
Warning:
Beware of the gold-colored liquid on the floor. If you run on it, it will cause you to slide out of control and into a wall of spikes.
Now you have decision to make. There are five tunnels and you need to decide which way to go. Here's the way things breack down: the first tunnel (count from left) connects to the fifth tunnel; the second and forth tunnels take you to fights against creatures known as Stingers.
Note:
There's one path that you must travel through - the second tunnel. You can skip the fourth path and avoid a tough fight, but keep in mind that skipping the fourth path means passing up an item.
Note:
There are two secret passages in this chamber. Follow the arrows on the map to find the hidden chests.
Before you approach the troll-like face in the wall, equip yourself with something that grants protection from fire. You'll need it because when you walk up to the face, it comes to life and attacks the party.
Boss Fight: Gi Nattack and Soul Fires
Warning:
Gi Nattak can steal your MP and HP, so you may need to use several Ethers.
This boss can be real pain, mainly because its Soul Fire henchmen have the ability to posses your characters. once inside a character's body, it will occasionally cause fire damage. They can also heal themselves using their own Fire magic.
You can equip your team with gear that helps protect from fire to make this an easy fight. Gi Nattak's main weakness is Holy magic. This may seem odd, but the undead take damage from Cure spells - just avoid using Fire spells.
Also, make sure you use your Summon Materia, either "Chocobo/Mog" or "Shiva". Only use your normal attacks when you are out of MP. Defeating this Boss gets you a Phoenix Down and a Wizer Staff.
Follow Bugenhagen and the others out of the cave, and pick up the "Gravity" Materia on the way out.
Because of these actions, Red XIII finally sees his father's true fate - he was a hero after all. Now Red XIII can speak with pride when talking about his father. Bugenhagen asks Red XIII to continue on with the party so that they can make a difference. Red XIII meets up with you as you leave town.
Continue southwest out of Cosmo Canyon, and then head north along the coastline to reach your next destination, Nibelheim.
