The Items are:
Rhetts Huge Conch:
Hold this item softly aginst your check (or ear) and yo uwill hear the whispering of the ghosts of the lost crew. Their voices will get stronger the closer you get to some (not all) of the more haunted locations you find clues.
Rons Conch:
See above but the conch is not as big and may have problems with the whispers comming out before you expect.
The Medallions of the lost Tiki's
These necklace of sunken tiki gods may help with messages on some of the clues found at the locations. Just let them read it in the dark and they will show you the way to the next location!
Drunken Scribblings:
A scrape of paper contianing scribblings of codes reveal the other locations. The only problem is that the pirates where drunk when they wrote them out. and they may have ripped the Code in seperate pices when they had their struggle on the ship. You may even need this to cypher some of the clues that the other items reveal.
I may make more if i can think of some....or maybe i wont get these made (I will try my best to make these items a part of the hunt but the details and specifics are all only a possibility at this time and i am not responsible.
