If you’re aiming to fully upgrade Kratos’ Leviathan Axe and unlock the Darkness and Fog trophy in God of War, you’ll need to conquer Niflheim—a deadly, mist-shrouded realm filled with traps, monsters, and valuable loot. This step-by-step guide will walk you through everything you need to succeed.

How to Unlock Niflheim

To access Niflheim, collect four Niflheim Language Ciphers, found in special purple cipher chests throughout the game. Once all four are gathered, the realm becomes accessible via Tyr’s Temple in Midgard.

Surviving the Misty Maze

Niflheim features a procedurally generated maze filled with traps, enemies, and a resource called Mist Echoes, which you’ll use to unlock powerful upgrades. But be warned: the longer you remain in the mist, the faster the pink life-draining meter depletes. If it runs out, Kratos dies—and you lose any unbanked Mist Echoes.

Tips for Surviving Niflheim:

• Follow a Counterclockwise Path: While enemy spawns and traps change, the maze layout stays mostly consistent. Moving counterclockwise helps maintain orientation.
• Loot Quickly but Carefully: Each chest holds Mist Echoes and useful enchantments. Move swiftly, but stay alert for traps.
• Wear Niflheim-Specific Gear: Equip armor that reduces mist exposure, allowing for longer runs.
• Always Bank Your Echoes: Return to the central chamber before dying to make your Mist Echoes permanent.

Unlocking the Chilling Mists of Niflheim

To upgrade the Leviathan Axe from Level 5 to Level 6, you must collect the Chilling Mists of Niflheim, which is found in a high-cost chest within the central chamber of the maze.

Steps to Acquire the Chilling Mists:

1. Farm Mist Echoes: Collect at least 5,000 Mist Echoes by repeatedly running the maze.
2. Open the 5,000 Echo Chest: This chest contains the Chilling Mists of Niflheim.
3. Trade at Sindri’s Shop: Go to Buy Resources and exchange the Chilling Mists for a Frozen Flame.
4. Upgrade the Leviathan Axe: Use the Frozen Flame to upgrade your axe to Level 6, earning the Worthy trophy.

How to Earn the Darkness and Fog Trophy

To unlock the Darkness and Fog gold trophy, you must open all chests in the central chamber of Niflheim. Many of these chests cost upwards of 5,000 Mist Echoes, so expect to make multiple runs through the maze.

Tips to Maximize Mist Echoes:

• Aim for 6,500–9,000 Echoes per run once geared.
• Prioritize fast enemy kills to reduce time spent in the mist.
• Fully upgrade Niflheim armor sets for improved mist resistance.
• Memorize the rune chest locations for efficient runs.

Once all central chamber chests are opened, the Darkness and Fog trophy will unlock.

Final Thoughts

Niflheim can be one of the most challenging parts of God of War, but it’s also one of the most rewarding. With consistent effort, you’ll master its layout, optimize your runs, and earn both a fully maxed Leviathan Axe and one of the game’s rarest trophies.

Good luck—and may the mist work in your favor.
