Hey all, good to see that somebody put time in to do a game discussion for the various Tall Tales.
When I got stuck, I used https://rarethief.com/sea-of-thieves-tall-tales-guide/
Some of the images can be deceiving, but it should help you get 'em done.
And don't forget to read all the journals for each Tall Tale. Rare Thief also has a separate journal guide. Quite handy.
