Before entering the Sealed Cave, farm bestiary entries at the Three Tile Peninsula (a tiny strip of land south of the Sylvan Cave). Land there and fight until you register Gloomwing, Gorgon, Crawler, Tarantula, and Yellow Dragon. Yellow Dragon is rare but guaranteed with a Siren. And then fly to the cave northwest of Tomra.
Sealed Cave
Interact with the entrance door and use Luca's Necklace to unlock it. Every door inside triggers a Trap Door encounter (5,000 HP each). Fight them all; they give excellent EXP and sometimes transform into Chimera Brain or Yellow Dragon for extra bestiary entries. King Naga is also common here if you missed it earlier. Save the Fuma Shuriken from the chests for the final boss.
B1. Go south through the rope, then open the chest at the bottom for a Bestiary (277/342). Head north and go through the southeast door. Two chests: Kotetsu and Ether (278-279/342). Exit. Head west, then north through the rope. Go through the northwest door. Two chests: Hi-Potion and Ether (280-281/342). Fight the empty doors for EXP, then take the southeast stairs to B2.
B2. Head south through the rope for a Bestiary (282/342). Go back north and east for a Phoenix Down (283/342). Continue north along the narrow ledge. Four doors line the top row (right to left). Second from right: Light Sword (284/342). Third from right: Fuma Shuriken, Elixir, and Light Curtain (285-287/342). Leftmost: Kotetsu and Black Cowl (288-289/342). The second from left is a save room. Head southwest through the door, grab the Ether on the path (290/342), and take the southwest stairs.
B3. Open both chests in the small area: Hi-Potion and Phoenix Down (291-292/342). Head south across the bridge, then east for a Bell of Silence (293/342). Go through the middle rope and break open the eastern door. Two chests: Dry Ether and X-Potion (294-295/342). That's 19/19 chests.
B4 and B5 are linear with no chests. Head down to the Crystal Room.
How to beat Demon Wall
Grab the Dark Crystal, then head back. The Demon Wall has 28,000 HP and advances toward the party over time. When close enough, it uses Crush to instantly kill one party member. This is a DPS race. Spam Leviathan with Rydia, Jump with Kain, Attack with Cecil and Edge, and cast Haste with Rosa to speed up your turns. Kill it before it reaches you.
Walk all the way back to B1. A cutscene triggers at the entrance and Kain leaves the party again. Exit the cave.
Side quests
Return to the Dwarven Castle throne room. The airship is upgraded to travel between the underworld and overworld. Fly to the northeast crater to ascend.
Adamantite. Pick up the Enterprise airship (check the blue diamond on the map) and grab the hovercraft. Take it to the Mythril area and drive southeast to the Adamant Grotto. Give the Rat Tail to the NPC inside to receive Adamantite.
Frying Pan. Fly to Fabul Castle. Head to West Tower 3F and speak to Yang's Wife to receive the Frying Pan.
Excalibur. Fly to the underworld and visit Kokkol's Smithy in the southeast corner. Check the pot on 1F for a Remedy (49/54) and the left shelf on 2F for a Soma Drop (50/54). Give Kokkol the Adamantite. He needs time to forge it. Leave.
Sylph summon. Head to Sylvan Cave. Make your way to the Sylvan Cottage (B1 → B2 → south to B1 → southwest to B2 → northwest to B3 → Cottage). Use the Frying Pan on Yang. Rydia learns the Sylph summon.
Knife. Return to Yang's Wife at Fabul West Tower 3F and hand back the Frying Pan. She gives you the Knife, which always deals 9,999 damage when thrown by Edge. Save it for the final boss.
