Some of Genshin's most valuable rewards — weapon billets, exclusive furniture blueprints, and lore that recontextualizes the entire story — are locked behind world quests that many players never start. Either the quest giver is in an obscure location, or the unlock condition requires a specific time cycle or prior quest chain.
Here are 10 hidden world quests that every player should do, ranked by reward value.
The quest hook appears only after you've collected all 8 Carp of the Blessings and offered them at the Sacred Simulacrum. Most players find the carp in their inventory and never figure out the trigger.
Why it matters: The quest unlocks a hidden domain with a permanent weapon billet + 60 primogems, and the final cutscene reveals the Jade Chamber's original construction blueprints — a lore detail that connects Liyue's architecture to a character who hasn't been mentioned since the archon quest.
This quest activates when you walk near a small, unmarked stone table in the Chasm's deepest section. There's no NPC, no quest marker — just a glowing interact point that appears only after you reach Adventure Rank 46 and complete the Chasm world quest chain.
Why it matters: The quest reveals a full recording of the previous Pyro Archon's final battle, told through Khaenri'ahn machinery. It directly connects the Chasm disaster to the cataclysm 500 years ago and explains why the "Nail" was deployed.
One of the oldest hidden quests in the game. A ghostly NPC spawns only during night hours near the Frostbearing Tree's underground chamber. Most players assume the area is empty after completing "In the Mountains."
Why it matters: The quest tells the story of a Mondstadt adventurer who discovered Dragonspine's truth before Albedo — and why the Knights of Favonius covered it up. Ends with a hidden achievement and unlocks a second chest in the Skyfrost Nail area.
This quest is missed by 90% of players because it's unlocked by finding a specific clockwork meka that doesn't talk. You need to examine it 4 times over 4 real-world days, each time finding a different "letter" inside its chassis.
Why it matters: Over the 4 days, you piece together an epistolary story about a Fontaine researcher who smuggled information about the oratrice into the Fortress before the prophecy. The final letter hints at the true identity of the Knave's predecessor.
One of the only quests in Genshin gated by weather. Talk to an old fisherman near the Liyue Harbor dock while it's raining (not after, while). He'll ask you to retrieve items from 3 shipwrecks across Liyue, Inazuma, and Fontaine.
Why it matters: The quest rewards a mysterious "Sea Chart Fragment" — and when you gather all 3 fragments from different regions, they combine into a map pointing to a secret underwater location near the Fontaine Research Institute. The final treasure: a 4-star weapon billet + 100 primogems + an achievement.
This quest appears only after you complete the Natlan Archon Quest Chapter 5, Act 4, AND reach reputation level 4 with the Children of Echoes tribe. Most players reach reputation 4, see no quest marker, and assume there's nothing else to do.
Why it matters: The quest unlocks a permanent domain that lets you convert 3-star weapons into refinement materials. A game-changing QoL upgrade that most players never unlock, despite it being completely free.
A cat gives you a quest, but only at midnight. And only if you have not defeated the Electro Hypostasis boss that week. The cat asks you to defeat it 3 times over 3 weeks to purify the shrine.
Why it matters: Completing this quest chain unlocks a secret shop NPC in Inazuma City that sells a namecard, a gadget skin, and a hidden recipe. None of these items are available anywhere else, and the shop disappears if you miss the weekly window.
The entrance to the hidden alchemy lab is blocked by a fake wall that only opens during the morning time cycle. Inside, you'll find notes from a researcher who worked with Gold (Rhinedottir) before the Cataclysm.
Why it matters: These notes are the only source of information about the "Art of Khemia" before it was used to create the Rifthounds. The quest rewards include a primogem-rich secret achievement chain (4 achievements, 50 gems each) and an exclusive teapot blueprint.
The secret: Enkanomiya has a meta-progression system. Finish all 8 standard world quests + collect all 50 Key Sigils + activate all 5 day-night mechanisms. Only then does the central tower's top floor open.
Why it matters: This quest explains the full backstory of the Heavenly Principles and the Second Who Came. Not through vague NPC dialogue — through interactive murals in a hidden chamber. This is the single biggest lore payoff in the game for players who invested time.
One of the most esoteric unlock conditions in Genshin. After an in-game timer of 60+ days following the end of the Golden Slumber chain, an Abyss Order camp spawns in a previously empty area. Inside is a letter from a mysterious member of the Abyss Order who knows the Traveler by their original name.
Why it matters: The letter contains the first clear mention of the Traveler's sibling's full plan — not just "they joined the Abyss," but why, and what they believe will happen after Teyvat's "cycle" ends. This is required reading for anyone who cares about Genshin's endgame narrative.
