Final Fantasy III/Cave of Shadows

''Using the power of Noah's Lute, the Warriors of Light can awaken Unei, Master of Dreams. She joins the party and helps restoring an old and powerful airship, the Invincible. With this new airship many new areas can be accessed and explored. The Fang of Earth is almost in your hands, and it is key to get the Earth Crystal.''

Suggested team for this chapter (from Falgabard):
 * Dark/Mystic Knight, but only after you find his equipment in Falgabard; in the NES, he can use White Magic;
 * Bard, because in this team he can support two physical fighters; in the DS, he can heal the party.
 * Viking, because of the lightning-elemental weapons;
 * Evoker, because of the new summon spells that can be obtained;

Unei's Shrine
Use Noah's lute (found in the underwater Temple of Time) to wake up Unei, who joins the Warriors of Light.

Ancient Ruins
Unei can remove the rocks that block the entrance to the lower levels. At the bottom, the legendary airship Invincible can be found. It allows to access all the subsequent areas in this page.

Falgabard
Falgabard is the town of the Dark Knights, therefore let's give a look to all the Dark Knight equipment, not only to what is available here.

In Falgabard you can find full equipment for one Dark Knight for free: a Demon shield, a Demon armor and a Kiku-Ichimonji Dark Blade. To obtain such Kiku Blade you have to defeat an old Shinobi who lives under the waterfall.

Falgabard Cave
Optional dungeon. Access from the town of Falgabard. Some chests can be found in it, but they contain nothing essential (see tables above). The value of this area is training the Warriors of Light in fighting splitting enemies and finding invisible passages.

Lake Dohr
Optional dungeon. Access using the airship Invincible near the Living Woods. Enemies are very strong, so the debuff abilities of the Evoker and the Bard will be necessary; moreover, most enemies are weak against Lightning element, therefore the Viking will be very useful too. Defeat Leviathan to obtain a Summon spell.

Bahamut's Lair
Optional dungeon. Access using the airship Invincible near Tozas. Enemies are just slightly stronger than in Lake Dohr, but your team is more experienced now; on the other hand, enemies aren't weak against lightning anymore. Defeat Bahamut to obtain a Summon spell.

Cave of Shadows
It conceals the Earth Fang, necessary to access the areas in the next two chapters. It is guarded by a boss, Hecatoncheir.
