With the Earth Crystal restored, sail southwest from Melmond past the Cavern of Earth peninsula. Keep going west across the sea until you hit the eastern shore of the next continent. Dock at the port and walk southwest through the forest, around the crescent-shaped lake until you get to town.

Melmond to Crescent Lake

Crescent Lake

The town sits at the edge of a large forest. Cross the bridge in the northeast to find the Circle of Sages. Talk to the sage to the right of Lukahn and he gives you the Canoe, which lets you travel on rivers.

The magic shops sell Level 6 spells for 13,000 Gil each. Thundaga is your Black Mage's priority; Stun and Quake are solid picks too. For White Magic, grab Protera and Invisira for boss fights, but leave one slot open for Exit after class change. Don't spend too much on Mythril equipment here. Mount Gulg's chests have better gear for free.

River to Mount Gulg

Crescent Lake to Mount Gulg

Use your new Canoe on the rivers west of Crescent Lake.

  • Paddle west until you hit a fork, take a right.
  • At the second fork, take a right and then take a left.
  • At the final fork, take the left and follow the path until you reach Mount Gulg.

The river enemies give good EXP if you want to grind. Crocodiles and Hydras are weak to Thunder, so Thundara and Thundaga make quick work of them.

Mount Gulg Directions

B1. Walk to the northwest point of the map and head down the stairs.

B2. 18 chests on this floor, many grouped together.

  • Take the second door. There'll be a chest immediately in front of you but it contains monsters.
  • Follow the path north and grab the chests along the way. Walk to the top right corner and take a left; before the second-to-last path, head down and grab the two chests there too.
  • Head south into a room with 12 chests, a few of them have monsters. You can fight them if you want the experience.
  • Go north and take your first available right, head south through the door. On the corridor, take a left to go down to B3.

B3. Walk far east until you find some stairs.

B4. Go to the southeast corner of the room and up the stairs to another part of B3.

B3. Go to the southwest corner and walk down the stairs to B4.

B4. 15 chests on this floor.

  • Open the door in front and grab the two chests; both contain monsters.
  • Follow the path until you see another room. One chest in here with 1,760 Gil.
  • Head west to a room at the end with 5 chests, two of which contain monsters.
  • Go south and you'll find a room being guarded by a monster; take him out and get the two chests.
  • Take a right for a room with 3 chests. Then double back and go south this time. You'll spot another room with 2 chests, both containing monsters.
  • Keep going south until you reach the stairs taking you to B5.

B5. 4 chests on this floor (yes, only 4). Getting them completes the Mount Gulg set at 37 total.

  • Walk immediately west into the room. Chest guarded by a monster; the chest itself has a monster too.
  • Northeast room for a chest. Eastern room for a chest. Southeast room for a chest.
  • And in the southeast room, you'll find the second Fiend, Marilith.

Marilith

The Fiend of Fire hits harder than Lich. She gets six attacks per turn and throws Fira on top of that, so your whole party takes damage every round. But if you picked up the Ice Brand from B4, your Warrior's in good shape. Worst part? She can cast Hold and lock down a party member at the worst possible time.

Defeat Marilith and the Fire Crystal is restored. Step into the portal to exit Mount Gulg.

Take the canoe back to Crescent Lake.
