Legends of the Stone Lock in Genshin Impact is a permanent Sumeru search problem with a specific unlock or completion route. Legends of the Stone Lock is a hidden Sumeru quest tied to the green stone seals placed around Ruin enemies. The quest becomes relevant after you free the sealed machines across the rainforest and leads to an underground Perpetual Mechanical Array encounter.
For Legends of the Stone Lock, the important part is separating the visible destination from the progression flag behind it. In Sumeru, reaching Legends of the Stone Lock physically does not always mean the quest, mechanism or reward is ready, so the order below avoids unnecessary backtracking.

Legends of the Stone Lock in Genshin Impact becomes much easier once the required progression is in place. Check these conditions before committing to the route, especially if your map already shows Legends of the Stone Lock but the interaction itself is not working.
- Have Sumeru rainforest exploration open.
- Carry Pyro because the green Stone Lock seals are burned away with Pyro.
- Free the sealed Ruin machines found across the region instead of ignoring them as scenery.
Step-by-step route
- Locate the green Stone Lock mechanisms surrounding trapped Ruin enemies.
- Use Pyro to break the seals and defeat each released machine.
- Continue clearing the sealed machines until the hidden Aranara progression becomes available.
- Follow the Aranara into the underground route when the quest starts.
- Drain the deeper lake and complete the final Perpetual Mechanical Array fight with Aradashan and the others.
During Legends of the Stone Lock in Genshin Impact, keep the relevant quest or map layer visible instead of navigating only by the surface marker. Around Legends of the Stone Lock, Sumeru uses underground routes and progression-gated interactions heavily, and the intended path often becomes obvious only after the previous step has registered.
The quest is hidden, so normal blue World Quest markers do not guide you to every prerequisite.
The sealed enemies include multiple Ruin enemy types spread through the rainforest.
Why it can still look locked or incomplete
If the quest will not appear, the usual issue is an uncleared Stone Lock somewhere in Sumeru. Revisit known green-sealed machines and make sure each one was actually released and defeated.
If Legends of the Stone Lock in Genshin Impact seems stuck, compare your current objective with the prerequisite list before assuming the game has bugged. The most common failure point around Legends of the Stone Lock is reaching the correct location one quest step too early or solving only part of a multi-stage mechanism.
Useful details before you leave the area
Completing the chain opens access to a previously flooded underground area and additional exploration.
Legends of the Stone Lock in Genshin Impact is permanent content, so there is no reason to rush past useful waypoints or shortcuts once the main blocker is cleared. Registering the local teleport and checking newly opened rooms saves a surprising amount of time when later quests send you back to Legends of the Stone Lock.
Legends of the Stone Lock in Genshin Impact is easiest to finish when the prerequisite and the local mechanism are treated as one connected route.
Common questions
Why is Legends of the Stone Lock not working for me?
For Legends of the Stone Lock in Genshin Impact, the usual causes are incomplete prerequisite progression, approaching from the wrong map layer, or missing one local interaction. Work backward from the current Legends of the Stone Lock quest text rather than redoing unrelated exploration elsewhere in Sumeru.
Is Legends of the Stone Lock permanent?
Yes. Legends of the Stone Lock is part of permanent Sumeru content rather than a limited-time event. Later game updates can adjust interface details around Legends of the Stone Lock, but its underlying quest or exploration route remains available to accounts that have not completed it yet.
What should I do next?
After the final battle, explore the drained underground chamber before leaving because it is easy to miss nearby chests and routes when focusing only on the quest completion banner.
After Legends of the Stone Lock in Genshin Impact, the next useful move is to finish the nearby follow-up content while the route is fresh. HoYoverse keeps current game notices on the official Genshin Impact website if a later update changes any interface or progression detail around Legends of the Stone Lock.
