If you’ve spent any time wandering the frosty, pine-dusted slopes of Inazuma’s highest peak, you’ve almost certainly run into the ghost of yotei mountain reliquary puzzle at some point. I first stumbled on it by accident when I was hunting for hidden crystal marrow chunks, and I spent 45 minutes running in circles trying to figure out what the tiny blue ghost wanted before I finally cracked the code. This guide skips all the trial and error I went through, so you can solve the puzzle fast and claim all the rare rewards waiting for you inside the reliquary.
What You Need Before Starting the Ghost of Yotei Mountain Reliquary Puzzle
You don’t need to complete any long world quests to unlock this puzzle, but there are a few simple prerequisites you’ll need to check off first to avoid getting stuck halfway through. Most of these you probably already have if you’ve been exploring Inazuma for a while, but it’s worth double checking before you make the hike up the mountain. You’ll also want to make sure you’re not visiting during a thunderstorm, because the ghost will not spawn if there’s lightning in the area.
- Unlocked Yotei Mountain area in Inazuma (available after reaching Adventure Rank 30 and completing the Ritou Escape Plan archon quest)
- Acquired the Peculiar Pinion gadget from the Sacred Sakura Cleansing Ritual questline
- At least 3 empty inventory slots for puzzle rewards
- A Pyro character in your party to clear frozen obstacles blocking clue locations
Pyro abilities are non-negotiable here, because one of the clue locations is buried under a thick sheet of ice that only Pyro damage can melt. You can use any Pyro character, even a low-level one, so just slot one into your party before you head out. You don’t need any other specific elements for this challenge, though an Anemo character with crowd control can make the small enemy encounters go faster.
Step-by-Step Walkthrough to Complete the Puzzle
Start by teleporting to the western Yotei Mountain waypoint, the one perched just above the small frozen lake. Turn south and walk behind the cluster of three pine trees, and you’ll see a faint blue figure of a young girl standing next to a half-buried stone tablet. Equip your Peculiar Pinion and interact with her to start the puzzle. She won’t speak, but she’ll point at the stone tablet before floating away.
Don’t skip reading the tablet, it has the exact order of the 5 symbols you’ll need to activate at the final reliquary door. I recommend taking a quick screenshot of the symbols so you don’t have to hike back to check later if you forget. Once you read the tablet, three small floating blue orbs will spawn one after another, each leading you to a small mini-challenge. The first orb will take you to a group of 3 Cryo slimes you’ll need to defeat, the second leads to a Pyro torch you need to light to melt the ice covering a small note, and the third leads to a snow fox den you just need to stand next to for 3 seconds.
After you interact with the third orb, the ghost will reappear and lead you straight to the reliquary door, tucked in a small cave behind a frozen waterfall. The front of the door has 5 stone symbols arranged in a row, and you just need to tap them in the exact order you saw on the first tablet. Get the order wrong and you’ll have to wait 10 minutes for the puzzle to reset, so pull up that screenshot you took earlier to double check before you start tapping. When you enter the right order, the door will creak open automatically, and you can head inside to claim your rewards.
Common Mistakes to Avoid That Waste Your Time
Even if you follow the step-by-step process, small slip-ups can set you back 10 minutes or more, so keep these pitfalls in mind as you work through the challenge. First, don’t forget to equip the Peculiar Pinion gadget before you head to the ghost’s spawn point. I made this mistake my first attempt, and I stared at a faint blue glow for 15 minutes before I realized I hadn’t swapped the gadget on from my wind glider. Leave all snow foxes alone while you're working through the puzzle — I still kick myself for attacking one mid-orb chase on my first run, and the ghost vanished immediately, forcing me to start over from the beginning. The foxes are part of her backstory, not enemies, so just walk past them if they cross your path.
Another common mistake is trying to interact with the reliquary door before you collect all three floating orbs. The symbol panel on the front won’t even light up if you haven’t finished the chase, so don’t waste time tapping at it over and over. If you do mess up the symbol order, you won’t get a second try right away: the puzzle locks for 10 minutes before it resets, so make sure you double check the tablet’s symbol order before you start tapping. Also, avoid logging out or teleporting away mid-puzzle, because you’ll lose all your progress and have to start back at the first spawn point.
What Rewards You Get for Solving the Reliquary Puzzle
The rewards for this hidden puzzle are way better than most random open world challenges, so it’s well worth the 10-15 minutes it takes to complete. The first thing you’ll see when you walk into the reliquary is a luxurious chest sitting on a stone pedestal in the center of the room. Open it up to get 40 Primogems, 3 Hero’s Wit, 20,000 Mora, and a couple of mystic enhancement ores. You’ll also unlock a hidden achievement called “Child of the Frosted Peaks” that gives you an extra 5 Primogems, which you can claim immediately from your achievement menu.
The most valuable reward though is the Yotei Mountain Snow Relic, a 4-star artifact that gives a 15% Cryo damage bonus when equipped as part of a 2-piece set. It’s perfect for powering up Cryo characters like Ganyu, Ayaka, or Wriothesley if you’re still working on building their optimal artifact sets. The relic has fixed substats that include 10% energy recharge, so it’s a great placeholder even if you don’t have a full Cryo team built yet.
Most players don’t know about the bonus reward you can get 24 hours after solving the puzzle. If you head back to the reliquary door the next day, you’ll find a small gift sitting on the step from the ghost: 10 crystal marrow chunks and a handwritten note thanking you for helping her recover her family’s lost relic. It’s a small touch, but it’s a huge help if you’re farming crystal marrow to ascend Cryo characters.
The ghost of yotei mountain reliquary puzzle is one of my favorite hidden challenges in Inazuma, because it’s tied to a sweet, understated little story and the rewards are actually useful for building your team. I hope this guide saved you the frustration of running around the mountain for an hour like I did on my first attempt.
