Mount Gulg — Marilith
- From Crescent Lake, canoe the rivers to the volcano Mount Gulg.
- Lava dungeon: bring Ice magic, Fire-resistant planning, many healing items.
- Explore every floor. Chests hide weapons and gil; some paths loop — use the map.
- Heal before the summit / crystal chamber.
Boss: Marilith (Kary)
- Element: Fire Fiend.
- Weak to: Blizzard / Ice family every turn from Black Mage.
- Threat: Multi-hit physical attacks can delete a mage. Protect + high HP frontliners matter.
- Open: Haste fighter, Protect party, Ice spam, Cure on whoever she focuses.
- After: Fire Crystal lit. Restock immediately.
Ice Cavern → Airship
- Travel to the Ice Cavern (northern icy overworld; airship not required yet — ship/canoe/walk as map allows).
- Slippery ice puzzles / pits: fall intentionally when the path demands; watch for undead and mages.
- Loot all chests. The prize is the Levistone (Levistone / Floater).
- Exit; take Levistone to the desert where the airship sleeps (Ryukahn Desert region). Use the stone to raise the Airship.
- Airship controls: land only on grass / clear terrain. Now the entire overworld is in reach.
First flights: Touch down near Cardia (dragon isles), Gaia, Onrac coast for later, and the Citadel of Trials. Do not rush Flying Fortress without Class Change and Oxyale story.
Citadel of Trials & Bahamut
- Airship to the Citadel of Trials (isolated castle).
- Inside: teleporter / throne puzzle floors. Read each room: sit on correct thrones, follow warp order until you claim the Rat’s Tail.
- Loot side treasures while warping.
- Fly to the Cardia Islands (dragon archipelago). Enter Bahamut’s throne room deep in the caves.
- Present the Rat’s Tail. Class Change upgrades all four heroes at once.

Re-shop the world
- Land in major towns (Gaia, Lefein later, older capitals) and buy every piece of armor your new classes can wear.
- Knights: fill heavy armor slots. Ninjas: best blades. Wizards: robes + ribbons later if available.
- Learn remaining mid-tier spells now that charge pools and levels support them.
- Next story: mermaids of Onrac and the Sea Shrine — Chapter 5.
