• Melmond visit; enter Earth Cavern; light Earth Crystal; defeat Lich

Marsh Cave — full steps

1. From Elfheim region, sail/walk to the Marsh Cave entrance on the overworld (swampy peninsula area).
2. Bring many Potions, Antidotes, and a Tent for the entrance. Undead and status pests live here.
3. Multi-floor cave: explore systematically. Open every chest — weapons, gil, spell tomes sometimes.
4. Undead: use Dia/Harm/Fire if available. Save Lv2+ charges for tough packs.
5. Bottom / key room: claim the Crown.
6. Warp/Teleport out if you have it; otherwise walk. Heal fully outside.

Astos → Matoya → Elf Prince

1. Return to the Western Keep with the Crown. Present it to the false king.
2. Boss: Astos. He hits with strong magic/physical hybrid pressure. Dispel darkness if blinded; focus fire; Cure every turn he spikes someone.
3. Rewards: Crystal Eye and Mystic Key (names can vary slightly by localization — PR uses clear key-item labels).
4. Sail/walk to Matoya; return the Eye. She brews Jolt Tonic (or equivalent wake potion).
5. Back to Elfheim castle: wake the prince. He grants the means to obtain TNT for the dwarves (or gives it via the story handoff — follow the prince/NPC instructions exactly).

Mystic Key tour — every major door

With the Mystic Key, revisit locked rooms. This is one of the biggest permanent power spikes in the game.

Melmond & the Earth Cavern

1. With canal TNT ready, visit the Dwarf Cave. Give Nerrick the explosives; he destroys the canal rocks. Your ship can now reach new seas.
2. Sail to the decaying town of Melmond. NPCs describe the earth rotting — the Earth Crystal is dark.
3. Buy remaining supplies. Rest.
4. Enter the Earth Cavern (Earth Cave) nearby. Long vertical dungeon with earth elementals, undead, and tight corridors.
5. Loot all chests floor by floor. Note vampire / undead rooms — Dia and Fire shine.
6. Optional mid-boss encounters (vampires etc.) before the Fiend: treat them like mini-Fiends with Protect/Focus fire.
7. Crystal room: confront Lich.

Boss: Lich (Earth)

• Element: Earth Fiend / undead nature.
• Weak to: Fire first; Dia/Harm/Holy lines also punish undead.
• Open: Haste on your best physical if you have it; Protect on the party; then Fire every Black Mage turn.
• Heal: One character dedicated to Cure/Cura when multi-target spells land.
• After victory: Earth Crystal reignites. World state updates; sages at Crescent Lake become the next story beacon.

Canoe & next chapter hook

1. Travel to Crescent Lake (circle of sages). They explain the four Fiends and grant the Canoe for river travel.
2. Canoe lets you travel rivers to Mount Gulg (fire) — Chapter 4.
3. Restock Fire-resistant prep: Ice magic for Marilith, plenty of hi-potions.
