Genshin Impact: How to open the hidden door in Dark Clouds In A Wine Bottle
If you are standing in front of a stone wall with a luminous patch on the ground, the quest Dark Clouds In A Wine Bottle has brought you to its one real puzzle. The way forward is not to fight anything or solve a riddle. You just need to build a Cube Prime Ice Construct on the glowing spot, and the wall will shatter to reveal the passage.
Why the construct matters
This quest in Genshin Impact is mostly a guided run from one marker to the next. The only point where players get stuck is this construct interaction. It is a quest mechanic, not a character ability. Any character can trigger it, and you do not need a specific element or weapon.
The construct appears at the glowing spot after you interact with it. Once it is built, it does the heavy lifting and breaks the stone automatically.
How to get through the wall
Follow these steps in order. The game will update your quest log as you go.
- Walk to the stone wall that has the glowing area on the ground just in front of it.
- Interact with the glowing area. That summons and builds the Cube Prime Ice Construct.
- Wait for the construct to finish. It will crack the stone and open the passage.
- Step into the opening and continue the quest.
After that, the rest of the quest is simple. You go to marked locations and talk to NPCs. No more combat puzzles or hidden switches are involved.
Troubleshooting a stuck construct
If the construct does not appear or the wall does not break, check a few things.
- Make sure you have completed all prior quest objectives. The quest is linear, so a missing step can block the interaction.
- Verify that the glowing spot is actually interactive. If it is gray or unresponsive, you may be too far along or not far enough.
- Stand close to the spot. The game expects you to be within a short range to build the construct.
- Let the construct finish its animation. If you move away too soon, the stone might survive.
Repositioning slightly can also help. Sometimes the game’s hitbox feels off by a few steps, and a small adjustment lets you place the construct correctly.
Common questions about the quest
Do I need a particular character?
No. The Cube Prime Ice Construct is tied to the quest progression, not to any playable character’s elemental skill. Bring whoever you like.
What rewards does this quest give?
The official reward breakdown is not listed in the source. Most Genshin Impact quests of this type hand out Primogems, Mora, and character experience materials. Expect something similar here.
Can I finish the whole quest in one session?
Yes. The quest is not time-gated. As long as you have enough time and patience with the construct, you can complete it in a single sitting.
After the passage opens
Once you are through, the quest continues without further puzzles. If you are looking for more side content, you can also look for guides on rescuing Acomitl and solving the Pale Mist Color Puzzle. These are separate challenges, but they show up in the same area and reward you for exploring.
That is the whole trick. Build the construct, break the stone, and keep moving.
