Muspelheim Language Ciphers
Four Muspelheim Cipher Pieces in God of War are needed in order to unlock the Muspelheim Realm, which contains the Muspelheim Trials. You will also complete the "The Realm of Fire" favor upon finding them all. There are more than four chests to be found in God of War, but some of them get locked out during the story, and some are more difficult to reach than others.
All Muspelheim Cipher Locations
The trick to the Muspelheim Ciphers is that they're contained in silver Chests with a floating mask in front of them, which Atreus stabs so that Kratos can open them. There is a random chance of finding a Muspelheim Cipher within them, however you'll find that you'll have them all by the time you start the A New Destination quest.
To that end, here's a list of where you can find six of these silver Chests early on in God of War, in the order you'll be able to access them. This will get you to Muspelheim as early as possible.
Forgotten Caverns Cipher Chest
The Forgotten Caverns is an optional Region in the north west of the Lake of Nine. There’s a shore you can dock at behind a part of the World Serpent, and it's accessible as soon as you can explore the Lake of Nine after speaking with the World Serpent for the first time.
After docking, simply climb up the yellow chain in front of you. There's a chest at the top on your left.
Cliffs of the Raven Cipher Chest
You can go to the Cliffs of the Raven as soon as you can explore the Lake of Nine for the first time. Find the dock in the north east of the Lake of Nine, in the ice-topped area closest to the Vanaheim tower. Once docked, head past the corpse of the dead troll and check the walls to your right to find a marked wall that leads up to some boards.
Break the boards and stand below it to help Atreus up. He'll lower a chain for you. You'll see the silver Chest right in front of you at the top.
Foothills Cipher Chest
Found during the main quest Path to the Mountain's "Pass through the tower and caves" objective, shortly after you meet Brok's shop in Tyr's Temple, the giant golden building in the middle of the Lake of Nine. After this you can go to the end of the long bridge and into the Vanaheim Tower, where you'll encounter your first Scorn Poles that leave clouds of poisonous green gas on the floor.
Shortly into this area you'll have to drop down to a lower floor of a cave, where you'll have to fight a Tatzelwurm. Before climbing out of this area, de-poison the area by hitting the Scorn Pole with your axe, and leaving it there to keep the air clean. Look for the large silver chest here and open it.
Alfheim Cipher Chest
Found during the main quest The Light of Alfheim's first objective - Find a Way to the Light. Right after killing your first three Dark Elves, you'll kill the pink organic roots blocking the way forward. When you pass through the opening, turn and look to your right to spot the chest.
The Mountain Cipher Chest
During the main quest A New Destination, right after adding Mimir... to your party. When you head down from the summit via the stairs, look to your left and you'll find this at the foot of the main platform of the mountain peak.
The River Pass Cipher Chest
- Requires: Shock Arrows
During the main quest A New Destination, you'll have to return to the River Pass via the Lake of Nine route. Here you'll need to remove a wall of red sap with your new Shock Arrows. From here, turn right to find a side-room that has this silver Chest in it.
