🕳️ Desolation Culvert Overview
Delve into the grotesque ritual of a mutated Golden Thief Bug, threatening the inhabitants near Prontera. This dream entity governs the foul sewers and, if left unchecked, could render the real GTB in our world immortal.
To summon the boss, parties must eliminate all 22 Immortal Bug Eggs within the instance.
But that's not all! There's a 1 in 4 chance that assassin-type clones (3x spawn) of the boss will appear, relentlessly pursuing you. Don't lose hope—seek out the special Immortality Essence and defeat it to instantly vanquish these manifestations of immortality, courtesy of our dream entity.

🗺️ Walkthrough
- Instance Cooldown Quest Name: Desolation of Culvert Fatique
- Map Name: 1@ant
- Speak to the Dream World Explorer in Morocc to learn about the Dream Zones and commence your journey into Desolation Culvert. Select Desolation Culvert from the menu. You must be at least level 90.
- You'll be informed that you're far from reality and must eliminate the Immortal Bug Eggs.
- Proceed to hunt the eggs to halt the immortality ritual. Be cautious of mutated bug species unique to this area.
3.1 There's a 1 in 4 chance that 3 Immortality Essence Bugs will spawn. Exercise extra caution when this occurs at the start.
- Once all eggs are destroyed, a location will be marked on your mini-map, indicating the arrival of the Dream Entity, Desolation Bug.
- Ensure the number of spawned eggs never reaches 10. If this threshold is met, Desolation Bug's scales will harden, doubling its DEF and MDEF, making it significantly harder to defeat.
- The more eggs present, the more the battle area becomes constricted due to Poison Mists. Once the egg count drops to 0, all poison mist spawns will disappear, leaving only the Poison Mist Gates.
- The higher the egg count, the more powerful Desolation Bug's self-healing becomes, as it strives for immortality.

💡 Strategy Tips
- 🔍 Assign one player as a dedicated egg-killer during the boss fight.
- 🧠 Avoid allowing the egg count to reach 10.
- 💀 If your party has strong DPS, maintaining fewer than 4 eggs may be manageable.
- 🧪 If Immortal Bugs spawn, carefully inspect all eggs. These 3x mobs have no skills but high attack, and will relentlessly pursue anyone they aggro.
