This guide shows the complete walkthrough for Thus Was the Work Done in Vain World Quest in Genshin Impact 2.8 Summertime Odyssey event, which started on 15th July 2022 and will end on 24th August 2022. There are two versions of the map on Minacious Isle. So pay attention to where you are at. I will call the two maps Map A and Map B as shown in the picture below. You can change the map by interacting with Minacious Pool.
Quest Starting Location
You will get the quest by reading a note in Minacious Isle Map A at the location shown in the pictures below. This quest will be available only after you have completed Like Rhyme and Song, the Summer Reverie quest.
Go to the Island Within the Lake to Check the Ruins of the Past
After reading the note, go north and interact with the pool as shown in the picture below to change the map to Map B.
Go to the place on the Lake Island where the notes were left
As soon as you get teleported to Map B, turn left and jump down the ruins. Enter the secret chamber through the hole in the wall as shown in the picture below.
Find a way to open the Secret Chamber
As you enter the secret chamber, its gate will close. Inside the chamber, you will see three torches. Light them up in an anti-clockwise fashion (Starting with the one on the right corner) to open the gate.
Etch hints for Wolfgang
After the gate opens, don’t go inside. Interact with the yellow mark to etch hints for Wolfgang.
Return to the outside of the lake to check Wolfgang’s notes
Go back to the pool and change to Map A. Then take the wind current to reach the note as shown in the picture below.
Go to the ruins on the ocean surface to search for traces of Wolfgang
Your next objective marker will be on the west side as shown in the picture below.
Again go back to the pool and change to Map B. As the map changes, climb up the stairs on the west side and take the wind current ahead of it. Use the wind current to climb up the mountain on the south side. Keep climbing up the mountain in the south direction and eventually, you will reach another pool as shown in the picture below. Interact with the pool and it will teleport you to the ruins on the west side.
Jump down the ruins through the hole on the floor. Then climb up the hole in the wall. Immediately turn right and destroy the big rock ahead. this will reveal another small hole in the wall. Jump down through this hole and investigate the rocks in front to get Sea Salt Crusted Key as shown in the picture below. You will be needing this key later.
Now turn left and proceed ahead in the linear path. Read the note in the final room as shown in the picture below to complete the objective.
Go to the place on the Lake Island where the notes were left
Trace your way back to the top of the ruin and use the pool to teleport back to Map B. Then enter the ruins through the hole on the wall near the pool as shown in the picture below.
Proceed ahead and you will reach a room with two levers. Pulling these two levers open the gate on the ceiling of the room. Pull the levers as fast as you can and then climb up through the hole in the ceiling before the gate closes.
On the upper level, use the Sea Salt Crusted Key to open the gate. You will now enter a room with a locked chest and vases as shown in the picture below. Destroy the seven vases in the room as fast as you can to unlock the chest and open the next gate.
As you proceed ahead, you will see a Starlight. Chase the Starlight to its destination as shown in the picture below. In the same room, you will see a hole in the wall. Go through this hole to find another Starlight. Chase this Starlight too to its destination. Now capture both the Starlight Coalescence and proceed to the next room.
Find a way to escape the secret chamber
As you enter this room, the gate will close and you will be locked inside. Here you will see three torches and a big stone blocking the path as shown in the picture below. First, break the big stone to reveal the fourth torch behind it. Then use an Anemo character to remove the purple mark from torches 1 and 3 as shown below. Then light the torches 1-2-3-4 in this sequence. This will open the gate.
Look for a place to leave hints
Go back to the room where you caught two Starlight Coalescence and interact with the yellow mark there in the corner to leave hints.
Return to the outside of the lake to check Wolfgang’s notes
Go back to the pool that teleports you to the western ruins on Map A. Jump down the ruin. Then climb through the hole in the wall. Turn right and jump down through another hole in the wall. Proceed ahead and you will find the note lying on the ground as shown in the picture below.
Go to the now sunken Highland Ruins
Go back to the top of the ruin. Then take waverider to go to the quest mark location as shown below. Interact with the etchings on the marked location as shown in the second picture below.
Go to the Island within the lake to check the highland ruins
Take the waverider back to the western ruins on Map A. Interact with the pool there to reach Map B ruins.
Leave hints and a Sweet Madame
Ride the wind current to reach the top of the ruin. Here you will see several Star Guides. When a Star Guide is attacked, it shoots rays of starlight towards a specific direction and links up with other star guides. When you get close to a Star Guide, you can change the direction in which it is facing to help it link up to different star guides. To solve the puzzle, you need to link the Star Guides in a specific pattern. The pattern that you need to form can be seen by looking up in the sky. Use the picture below to solve the puzzle.
On solving the puzzle, a chest will spawn. Open the chest and a Starlight will come out from it. Chase the starlight to its destination and then capture it. Now place three Starlights in the Starlight Lamp as shown in the picture below. This will make a translucent stair appear that leads to the top of the ruins as shown in the second picture below.
Take the stairs to the top of the ruins. There you will find a luxurious chest. Interact with the pillar next to the chest to leave a message and a Sweet Madame as shown below.
Go back outside the lake to check Wolfgang’s etchings
Go back to the pool to teleport to the western ruins on Map A. Then take waverider to reach the objective marker as shown in the picture below. Interact with the pillar to complete the quest.
