Nestled far beneath the open waters of Fisch, Desolate Deep is a shadowy, hidden zone teeming with exotic deep-sea creatures, submerged hazards, and secret discoveries. Unlike the bright islands and sunny shores, this area descends into darkness, where brave explorers equip diving gear, follow shimmering buoys, and swim through hidden tunnels into an aquatic underworld rich with lore, valuable fish, and rare gear.
🔍 Overview & Setting
The Desolate Deep represents the depths of Fisch’s aquatic world. When you first arrive, you’re greeted by ghostly white mine markers, large boulders covered in kelp, clusters of glowing fish, and an eerie aquatic soundtrack. Fishers here can reel in unique species not found anywhere else, while adventurers can discover new equipment sold by a mysterious merchant.
The entire area is submerged except for one cavern-like escape that houses NPCs and acts as a safe zone. It’s an optional but highly rewarding region for mid-to-late game players aiming to complete rare fish bestiaries or access special gear upgrades.
🛠️ Diving Gear Requirements
To survive and thrive in the Desolate Deep, you’ll need minimum Basic Diving Gear, available at Moosewood’s docks for 3,000 C$. This simple suit enables you to swim deeper without churning stamina or drowning.
For a smoother experience, consider upgrading to Advanced or Mythical Diving Suits (purchased from extended NPCs or through quests). These provide increased oxygen, improved movement, and help you avoid accidentally striking lethal mines.
Route to The Desolate Deep
1. Start from Sunstone Island
Head to Sunstone (northwest of Moosewood), accessible by boat.
2. Follow open sea westward
Sail past the Statue of Sovereignty, follow the coastline beyond Sunstone, and keep an eye out for a floating red buoy in deeper water.
3. Dive under the buoy
Ride your surfboard or swim beneath the buoy’s centerline and dive straight down into the sea.
4. Locate the cavern entrance
Watch for a large white sign, then turn right into a hidden tunnel marked by shimmering rocks.
5. Avoid floating sea mines
Carefully swim past drifting mines hanging in the water column. Touch one and BOOM! – equip Advanced gear to give yourself more breathing room.
6. Swim towards the light
Keep swimming until the age opens into a glowing underground cavern full of aquatic life, NPCs, and fishing spots.
