Since this is Mona's domain, for the door 4 puzzle, the shapes should be a windmill (Mondstadt) instead of a squid.

>>13 You are absolutely right! Got my last chest now. Thanks!

>>14 thanks a lot, was literally scratching my head.

The second puzzle sequence for the door 1 chest is completely backwards

The last chest is most likely the Luxurious chest you get for completing the 2nd Challenge of the Starry Sky. You can get to the 2nd challenge by jumping into the water that's under the transparent pathways in Door 1.

To lower the water in the main room simply take one of the star pieces and put it back.

>>10 I had the same problem as you for ages but if we were stuck on the same chest but I found this video that helped me find the starry challenge and get that last chest: https://youtu.be/y1P6LyXI-r8

>>9 Same can't find the missing one

I did this guide and ended up with only 14. I did all the steps and everything, and only got 14. Is this guide incomplete, or am I just stupid?

door 3 part 4 flawed image and misleading take image from room entrance not some arbitrary location. Proper totem order based on entrance is center Front: Anemo Left: Pyro Right: Anemo Back: hydro. Also should mention players can alter character comp with the door of resurrection not all players will know this.

More issues door 3 says wall is passable yes sure you can see it with elemental sight but cannot pass nothing on how to do this. You find the water stone and destroy it to pass.

door 2 guide terribly incomplete, first puzzle does not show all the beam things in view nor clear direction due to image size. It also does not choose a clear POV of where the hell the image was captured from. (hint far left corner of room upon entering. It also leaves out the 2 start cubes flanking the room. Second part "just place item in totem" no explanation how the hell you get to that area with all the invisible paths then gives a terrible solution to the star puzzle from the wrong side.

Okay, but were we actually supposed to be able to figure these out on our own?

>>3 smack water stone in the same room

having trouble with the stone wall that should be passable, I've finished all parts of mona's quest but the wall remains solid. using elemental sight does highlight it white so it is different from surrounding walls. leaving and reentering the domain doesn't work. am I missing some prerequisite?

You missed a step in the final room. First do the tower with 5 points coming out of it puzzle, then switch to the shield, then go up.

had a bit of trouble figuring out some the solutions cause they didn't have the arrows like the guides for the other puzzles for this domain :(
