Dread Delusion Quest Guide — All Main & Side Quests Walkthrough

Quest Basics — How Dread Delusion Handles Quests

Dread Delusion doesn't hold your hand when it comes to quests. There's no quest log with waypoints and checklists. Instead, you get directions from NPCs, notes in your inventory, and your own memory. This can be frustrating at first, but it's also what makes the game special — you actually have to pay attention.

When an NPC gives you a quest, they'll usually mention a location, a landmark, or a direction. Write it down or take a screenshot. The game expects you to remember where you need to go. If you get lost, talk to the NPC again — they'll often repeat the directions.

Main Story Quests — The Critical Path

The main story of Dread Delusion revolves around uncovering the truth behind the world's destruction. Here are the key quests you need to complete:

A Broken Compass

Starting NPC: Elder Kael (The Bastion)
Objective: Find the missing compass pieces scattered across the starting islands.

This is your first real quest. Elder Kael tells you that the world was shattered by a cataclysm, and the only way to fix it is to restore the Compass of Worlds. The three compass pieces are located on small islands near the Bastion. Use your glider to reach them. Each piece is guarded by a few enemies — nothing too tough at this stage.

Reward: Basic glider upgrade (increases glide distance by 30%).

The Heretic's Path

Starting NPC: Sister Mira (Sanctuary of Whispers)
Objective: Investigate reports of heretical activity in the Ashen Catacombs.

This quest takes you to the Ashen Catacombs, a maze of ash-covered tunnels. The heretics are actually worshippers of an old god who was banished after the cataclysm. You can choose to help them or report them to Sister Mira. Helping them gives you access to a hidden merchant who sells rare sanity-restoring items. Reporting them gives you a unique blessing that increases your max sanity.

Reward: Choice between hidden merchant access or sanity blessing.

The Forgotten Forge

Starting NPC: Master Arin (The Bastion forge)
Objective: Find the lost forge key and restore the Bastion's upgrade station.

The forge key is located in the Sunken Vault dungeon beneath the Bastion. You'll need the grappling hook to reach it. The vault is filled with water, so be prepared for some swimming. The key is in a chest at the lowest point of the dungeon.

Reward: Unlocks weapon and armor upgrades at the Bastion forge.

The Observatory Secret

Starting NPC: The Astronomer (Observatory Island)
Objective: Activate the giant telescope and decode the star map.

The telescope requires three lenses to function. Each lens is hidden on a different island. The first is in the Floating Market (purchase from a vendor), the second is in the Spire of Echoes (guarded by a mini-boss), and the third is in the Forgotten Laboratory (puzzle reward). Once all three are installed, the telescope reveals the location of the final area.

Reward: Reveals the final island location on your map.

Best Side Quests — Don't Miss These

Side quests in Dread Delusion are often more interesting than the main story. Here are the ones worth seeking out:

The Herbalist's Request

Location: The Bastion (herbalist shop)
Objective: Gather three rare herbs from different islands.

The herbs are: Moonbloom (found on the Garden of Stillness), Ashroot (Ashen Catacombs), and Void Petal (Wreck of the Voidship). This quest rewards you with a permanent sanity restoration recipe that you can use anytime.

The Lost Crew

Location: Wreck of the Voidship
Objective: Find the logbooks of three missing crew members.

The logbooks are scattered across the wreck. Reading all three reveals the location of a hidden cache containing the Void Cannon — one of the best weapons in the game.

The Hermit's Riddle

Location: Hermit's Isle
Objective: Solve the hermit's three riddles.

The hermit asks you three riddles about the world's lore. The answers are found in books scattered across the various islands. If you answer all three correctly, he gives you the Hermit's Amulet, which halves sanity loss from reading forbidden texts.

The Isle of Whispers

Location: Appears only when sanity is below 30%
Objective: Complete a series of tasks for ghostly NPCs.

This is one of the most unique quests in the game. The ghostly NPCs on this island ask you to perform tasks that seem meaningless — but completing them all unlocks a secret ending. Be warned: spending too long on the Isle of Whispers will drain your sanity further.

Choices That Matter — Quest Consequences

Dread Delusion has several quests where your choices have lasting consequences. Here are the most important ones:

• The Heretic's Path: Helping the heretics locks you out of the Sanctuary's blessing, but gives you access to a unique merchant. Choose based on your build — the merchant sells rare upgrade materials, while the blessing is better for magic users.
• The Astronomer's Request: You can give the star map data to Elder Kael or keep it for yourself. Giving it to Kael advances the main story faster. Keeping it lets you discover hidden islands on your own.
• The Collector's Dilemma: A late-game quest where you must choose between saving an NPC or acquiring a powerful artifact. This choice affects which ending you get.

There's no "right" choice in most cases — just different outcomes. Play the way that feels right to you.
