Time to clean up chests that are locked by Mystic Key.

NOTE: The most important part in this section is to obtain a key item Nitro Powder from Cornelia Castle to continue the story.

There are 4 chests in the top-right corner room.

• (C-022) Myth ril Hammer
• (C-023) 800 gil
• (C-024) 700 gil
• (C-025) Bronze Gloves

There are 3 chests in the room to your left, guarded by monsters.

• (C-026) Power Staff (Monster): Left chest. 
  Mummy x5, one "Fira" should be enough to kill them all.
• (C-027) Falchion (Monster): Middle chest. 
  Wraith x6, again, use "Fira" to burn them all.
• (C-028) Steel Gloves (Monster): Right chest. 
  Mummy x5, cast "Fira".

Immediately equip these weapons.

There is a wizard in this Room (4,1), it's actually monsters when you talk to him. Psicodemon x4, use "Thundera" to finish them of in one shot.

• (C-029) Silver Armlet (Monster): Room (4,1). 
  Anaconda x6, just use "Fira" to quickly end the battle.
• (C-030) Antidote (Monster): Room (4,2). Psicodemon x4.
• (C-031) 1020 gil (Monster): Room (4,4). Psicodemon x4.

Leave the cave.

There are 3 chests here.

• Bottom room:
• (C-032) Rune Blade
• Top room:
• (C-033) Werebuster: Left chest.
• (C-034) Gold Needle: Right chest.

Equip these weapons immediately.

• Right room:
• (C-035) Cottage: Left chest.
• (C-036) Saber: Middle chest.
• (C-037) Mythril Knife: Right chest.
• Left room:
• (C-038) Iron Armor: Left chest.
• (C-039) Tent: Middle chest.
• (C-040) Nitro Powder: Right chest.

Leave the castle.

IMPORTANT: I highly recommend you buy some "Gold Needle" from Cornelia town before jumping to the next section. Our next dungeon has monsters that can petrify you.
