Sunkiller Sanctum Discoveries

Given that the map is a little bit confusing with many levels, I thought some descriptive comments could be useful. All the below are written for the 'Core of the Problem' variant:

I recommend pasting these coordinates right after you teleport to Focal Point (or whenever your map is set to 'Lower Sanctum' - check on the top-left corner for the dropdown menu).

Chest #1 (38.15 49 in the Lower Sanctum*):
Take the Singularity Portal (flight path/teleport) to Focal Point. Exit towards the west (*your map may switch to Upper Sanctum here). I encountered some Scouring Siphoids here (jellyfish-looking mobs). The chest is immediately to your left as you face the stairs, in a little nook behind the door frame. For me it contained 100 Voidlight Marl.

Chest #2 (49.7 50.55 in the Lower Sanctum):
Walk back to the Singularity Portal at Focal Point. Exit towards the southeast. Facing the Restoration Stone in the distance, the chest will be down the stairs to your left in a small room (clearly visible from the middle of the stairs). For me it contained 100 Voidlight Marl.

Chest #3 (60.1 40.75 in the Lower Sanctum):
Continue down the stairs from Chest #2. At the bottom - I encountered a Controlled Slaughterclaw just before - you'll see a long staircase heading up (directly in front of you as you walk down the stairs), and a short staircase going down (to your right - east on the map). The chest is clearly visible at the bottom-right of this second, small staircase as you go down, under a crystal formation on the wall. For me it contained a grey item worth 200g.

To paste the coordinates onto your map, you can use TomTom (open a paste window with /ttpaste and paste in the following) or paste each line individually onto your chatbox:

/tway 38.15 49 Chest #1
/tway 49.7 50.55 Chest #2
/tway 60.1 40.75 Chest #3

I got the 3rd chest on the story 'not what i expected' as a BM hunter with my feathermane pet and used updraft or you can use disengage backwards off the spike at these co-ords /way 57.42, 51.38

follow the path around up the stairs and its to the side of the doorway. but get this last after you have done the delve as the door at the top is closed
