Okay, imagine this: I was SO sure I'd cleared Liyue, 100% completion, the whole shebang. Then, my friend, a serious Genshin completionist (you know the type!), casually asks, "Hey, did you get all the Sanctuaire des Profondeurs in Liyue?" My jaw DROPPED. Sanctuaries? What sanctuaries? I’d been so focused on chests and oculi, I'd completely glossed over these sneaky little buildings. And that, my friends, is why we're here today. To talk about those very sanctuaries!
What are the Sanctuaire des Profondeurs, anyway?
Basically, they're fancy chests disguised as ancient buildings. Each one needs a Clef des Profondeurs – a key you get from completing certain quests, leveling up the Statues of the Seven, or sometimes, just stumbling upon them (lucky you!). Open the sanctuary, and BAM! Loot. We're talking Primogems, Adventure EXP, and other goodies that make your Traveler happy. (And let's be honest, Primogems make everyone happy).
Liyue's Sanctuaire des Profondeurs: The Hunt is On!
Liyue hides ten of these bad boys. Ten! That's a lot of exploring, especially considering how vast and gorgeous Liyue is. But don't worry, I'm not going to just leave you hanging. Here's the breakdown:
- Location, Location, Location: They're scattered all over the region, from the mountainous areas near Mt. Aozang to the coastal areas around Guili Plains. Keep your eyes peeled! (Pro-tip: Check your Adventure Handbook! It usually shows a general area).
- The Treasure: Inside each sanctuary, you'll find a precious chest containing Primogems, Mora, Adventure EXP, and character EXP materials. Think of it as a mini-jackpot.
- The Key to Success: Remember, you need a Clef des Profondeurs de Liyue to open each one. No key, no loot. Simple as that.
Finding Those Keys: A Mini-Guide
Alright, so how do you get these elusive keys? Here's a few common methods:

- Statues of the Seven: Leveling up the Statues of the Seven in Liyue (by offering Geo Oculi) will reward you with keys. This is arguably the most consistent method.
- Archon Quests and World Quests: Some quests, especially Archon Quests and certain World Quests, will give you a Clef des Profondeurs as a reward. Pay attention to your quest log!
- Adventure Rank Rewards: Keep leveling up your Adventure Rank! Sometimes, you'll get a key as a reward.
Why Bother? Is it really worth it?
Okay, I get it. Searching for these sanctuaries can feel like a chore. But hear me out. Those Primogems add up! Plus, it's a great excuse to explore parts of Liyue you might have missed. Think of it as a treasure hunt! And who doesn't love a good treasure hunt?
Honestly, I'm still kicking myself for missing these on my first "completion" run. Don't be like me! Go out there, explore, and grab those Sanctuaire des Profondeurs treasures! You won't regret it. Happy hunting! (And may your gacha pulls be blessed!)
