FINALLY! Found the Lost World Sea Chart last night after thousands and thousands of ships sunk and seemingly endless hunting for it. It seemed to me that everyone but me had it for years and I would never get it. It only took me 2 years ten and a half months to get. Been since shortly after the Admiral's Broadsword came out since I found a sailing only item that wasn't a dupe.
Yesterday I broke my record for Loot Skull Chests on a run, now 15, and the loot contained a Mistress Ching. I now have 98 Mistress Ching and just need one more to complete the 9 Rogues Collection, exciting!
