Eh, either one is entirely plausible, hope you got marking scrolls and/or darkness talent
unfortunately I’ve got the determination of a sloth so I decided finding and talking to 20 ghosts was to much work 
bruh you can talk to ghosts for help?
dark sea also works
Didn’t explorer’s intuition help you?
Or maybe the chart is just bugged?
Nah I literally covered the entire areas in digging holes. I just gave up I’m pretty sure the chart is cooked
West southwest of Ravenna is covered in sandy spots, each is a valid spawn for a chart. Run through them all with a goldsight shovel
^This
Also the actual roads/paths are also viable treasure spots
Explorer’s Intuition is a little inaccurate; sometimes you’ll find treasure an entire E.I. quadrant away from where it should be.
Don’t they just float to the part with the treasure?
Also, you could contribute some research, try alternating between two different ghosts at Akursius and see if the game counts it.
Try the same in the Abyss of Charon.
From what I recall, ghosts in both locations will count, and I think that if you just alternate between two, the game will forget you talked to the previous one already and count it.
Non-DS ghosts count towards that quest?
gub gub did u find it 
I never have the darkness talent equipped i have the stealth talent
Yup
I talked to 8 ds ghosts at most, all the others were from Akursius (I don’t fully remember the process) and AoC (I do remember this one)
the roaring captain
You know what, I bet there’s a noun ‘knight’
Which means a theoretical mythic/lost chart from the roaring knight is possible
Yes, this works, that’s how I did it
