Where is sink 17 in Genshin Impact 2.8

Continuing to collect Dreamshells on the archipelago in Genshin Impact 2.8, in the last guide we went for the sixteenth shell, and now we’ll go for the seventeenth.

First, we move to the Jagged Island to the drum, where we need to change the style of the islands.

We change the style of the mountains to low. Go to the cave to the right of the drum. The cave will be flooded, to remove the water, you need to light four torches. So we take Ember or another fire character and shoot the torches.

After lighting the four torches, you will need to light the monument. The water will go away partially. To remove the rest of the water you have to shoot the torches again, only the other ones. Two are visible, but the other two are hidden. The third torch will be under the stairs:

And the fourth torch is behind the door. There is also a grate behind the door, which must be opened by pushing the lever to the right.

Go through the door, light the torch and open the grate. Then we go back and activate the monument. The water level will drop and we can enter the arena, where we take the seventeenth shell.

In this arena we can also take the chest by shooting a note.

Now go after the three chests, for this we go back to the drum and change the style to appear high mountains, and go to the cave of the left rock, there used to be a grid, but we opened it, so now there is only a door, through which we can get to the arena with melodic colors.

We went down to the arena with the flowers (gramophones) and turned them so that the note flew further down the hallway.

The note will hit the barrier and reveal access to three chests.
