Part 4

Etrian Odyssey IV: Legends of the Titan Part 4 walkthrough covering the Underground Lake, Golden Lair, and Cloudy Stronghold dungeons.

Underground Lake

Monsters: Jumping Frog, Venomshroom. FOE: frozen Patrol Bat, Plated Chaser. Materials: Fennel, Glove Grass, Flame Fruit. Treasure: Spread Hammer B-2, Skull Crusher C-1.

You cannot finish collecting items in this dungeon until you obtain the Black Flame in the fourth land. Collect Fennel and Glove Grass from the gathering point at C-3. The Flame Fruit material and C-1 treasure become accessible after using the Black Flame to unfreeze the area.

Golden Lair

F1

Monsters: Magma Spawn, Glacier Spawn. FOE: Plated Chaser. Materials: Ice Stake, Luminous Moss, Scarlet Sage. Treasure: Red Doublet C-5, Ice Mist B-1, Amrita II D-2, 3000 D-2.

In this dungeon, small scales (respawn (be brought back to life at a checkpoint after death) after 1 day), big scales (respawn in 7 days), and ice stakes (harvested again after 1 day) are present. Use ice stakes from chop points to destroy small scales blocking your path. Materials from gather points, excluding ice stakes, vary based on whether the level is hot or cold. Look for blue hazes on the walls, which are shortcuts, to unlock at B-7, C-7, and D-4. These shortcuts ease return trips to the big scale that keeps F1 hot.

Plated Chasers are powerful FOEs but are easy to avoid due to their slow speed. Lure them to one side of a room and run around the other to evade them. Beware of their ability to slide across frozen water. If you choose to fight them, use physical attack counters, L's Power-Break, F's Strike Guard, or A's Charm Eye. They resist all three weapon types, so use fire or volt skills for effective damage.

Use an ice stake on the big scale at D-4 to freeze the water on F1. Then, take at least one ice stake from F1 and leave the dungeon via your skyship. Travel to the west/left entrance to reach F2 of the Golden Lair. Use the stairs at E-1 to access the left side of F1. With the water frozen and one ice stake, you can reach the Sentinel village at C-2. After some story events, you must fight Kibagami to proceed.

Kibagami

This mini-boss uses mostly weak physical attacks. L's Power-Break, A's Charm Eye, S's Arm-bind, and blinding him make his attacks less effective.

After defeating Kibagami, return to town to deliver the scroll to the guild and receive a mission from the Count. Once finished in town, return to the Sentinel village and use the stairs at E-4 to reach F2.

F2

Monsters: Baboon. FOE: Plated Chaser. Materials: Moss Strawberry, Trileaf Stalk, Poinciana Pod, Dried Vine. Treasure: 5000 E-2, Madora C-3.

You need 3 ice stakes to destroy F2's big scale at D-4. Reach D-4 via the path guarded by Plated Chasers or the longer path with many scales. At D-4, destroy the two small scales on the west side, then approach the big scale from the west. After destroying F2's scale, return to F1 and use the stairs at B-1 to reach the north side of F2. Leave the scale intact to access the treasure at C-3. On the north side of F2, use the stairs at B-6 to unlock a shortcut back to F1. Use the stairs at B-7 to reach F3.

F3

Monsters: Zapper Frog. FOE: Plated Chaser. Materials: Eclogite, Steel Earth, Emerald. Treasure: Bracers B-6, Ice Jar D-7, Fire Mist C-5, Formaldehyde C-5.

You will likely need to defeat some Plated Chaser FOEs to pass through F3; if you cannot beat them, you are not ready for the boss. Harvest extra ice stakes in the secret passages at B-5, D-7, and D-5. To obtain Steel Earth and Emerald materials, destroy the big scale on F3, then go up to F2 and use the stairs at D-5 to reach hidden mining points.

In the boss room, the lizard will start chasing you upon entry. If it gets close, exit through the south door and reenter; it will stop chasing. If the boss catches you, you can escape the battle by running. Focus on destroying the small scales on the west side to clear a path to the big scale. Destroying the big scale in the boss chamber freezes the boss and halves its health.

Boiling Lizard

Level recommendation: 35-40. This boss uses physical and fire attacks. Reduce fire damage by equipping fire rings, eating Sacred Mountain fish (boosts fire resistance), using R's Fire Rune, or L's Mental-Break. Use an ice stake to kill spawned scales. Use Kibagami's Roar skill if the boss auto-heals. The boss is weak to ice; L's Freeze Link and R's ice spells are effective. An N can also deal decent damage with ice element blades and Shadow Bite.

After defeating the boss, grab the heart and return to the Sentinel village on F1. Talk to the Medium on the left side of the village. After events, fly north to the fourth land.

Cloudy Stronghold

After a brief conversation, you must return to town to report to the Count. Receive your next mission, then go back to the Cloudy Stronghold. Proceed to the South Sanctuary dungeon, where you will eventually battle Logre.

Logre

Logre begins by attacking a front-line character with a powerful elemental attack. Have all front-line characters defend on the first turn, or revive whoever is killed. After his drive attack, Logre uses only weak physical attacks for several turns. He flees after losing half his health.

Return to town and speak with the Count. Your next task is to go to the Windy Ar.
