Abyssus Locked Door Guide – How to Get Keys

Locked doors in Abyssus block access to hidden areas with valuable rewards like weapons, upgrades, or secrets. To open them, you need keys, which are scattered throughout the game. This guide explains how to find keys and unlock those doors in simple steps.

What Are Locked Doors?

Locked doors are special barriers found in the lobby and various stages of Abyssus. They often hide treasures like new weapons (such as the Brine Revolver) or resources like Soul Fragments. Each door requires a specific key to open.

Types of Keys

There are three main types of keys in Abyssus:

• Iron Key: Opens basic locked doors in early stages and the lobby.
• Crystal Key: Unlocks glowing doors in later stages, often with better rewards.
• Relic Key: Rare keys for special doors tied to major secrets, like the Cabinet of Curiosities.

How to Find Keys

Keys are hidden in different places. Here’s where to look:

Iron Key

• Location: Found in Act 1, Stage 1 (Depth 1) or the lobby.
• How to Get:
  1. In Act 1, Stage 1, check side rooms or breakable objects like crates to find the Iron Key.
  2. In the lobby, search near the workbench or behind the waterfall for a hidden chest with the key.
• Use: Opens locked doors in the lobby or early stages, like a door near the Artefact Room.

Crystal Key

• Location: Found in Act 2, Stage 2 (Gardens) or Act 3, Stage 1.
• How to Get:
  1. In Act 2, Stage 2, defeat the miniboss to make a chest appear with the Crystal Key.
  2. In Act 3, Stage 1, look for a hidden platform above the main path. Jump to it to find a chest with the key.

Relic Key

• Location: Found in Act 4, Stage 1 or the lobby’s secret areas.
• How to Get:
  1. In Act 4, Stage 1, defeat one of the three elite minibosses (frog, skeleton, or snake) to get a Relic Key drop.
  2. In the lobby, complete the Secret Pond challenge (defeat all three elite minibosses to activate the fountain) to find a Relic Key in a hidden chest.
• Use: Opens special doors in the lobby, like one leading to the Cabinet of Curiosities, or rare doors in Act 4.

Tips for Finding Keys

• Explore Thoroughly: Check every corner of stages and the lobby. Break objects like barrels or vases, as keys often hide inside.
• Use the Logbook: The Logbook in the Artefact Room tracks which keys you’ve found and where to use them.
• Complete Challenges: Some keys, like the Relic Key, require beating tough enemies or completing tasks. Check the Logbook for details.
• Look for Hidden Paths: In the lobby, secret paths (like the one for the Brine Revolver) often lead to chests with keys.
• Retry Stages: If you miss a key, you can replay stages to find it again.

Opening Locked Doors

Once you have a key:

1. Approach the locked door. It will glow if you have the right key.
2. Interact with the door to use the key and unlock it.
3. Enter to claim your reward, which could be a weapon, resources, or a new path.

Why It’s Worth It

Locked doors hide some of the best rewards in Abyssus, like weapons (Brine Revolver, Fish Deity) or Soul Fragments for upgrades. Unlocking them also progresses challenges tracked in the Logbook, earning you cosmetics or other bonuses.

Final Note

Locked doors in Abyssus are gateways to awesome rewards. Hunt for Iron, Crystal, and Relic Keys by exploring stages, defeating enemies, and checking the lobby’s secrets. Use the Logbook to stay on track, and open those doors to claim your prizes. Keep exploring and enjoy the treasures waiting in the depths!
