Please Help - How to reach Isle of Dead ?

I played it and finished only 1 and i sided with the natives and i got the map to the Isle of Dead from the native chief daughter,so try this-maybe try there to see what it happens?Or try Caldera there is in the city at the hotel an voodoo priest but he is with the Inquisition,go to Carlos into Inquisition castle maybe he knows something,try also with Booze in tacarigua pirates den,or in maracay at the shaman N of the native settlement or try with Bones if you have him in party>I hope it helped.

Hmm try this go to antigua then go to the waterfall in antigua the big one wich shows as location go with Patty.That should trigger a mission "Open Sesame" then i think you can go to alvarez to tell you that the amulet is in Garcia chest.I got this line where to ask for the amulet from patty in tacarigua and i spoked with booze in the tavern to find out where it was.Or it may be a bug wich doesnt trigger the quest.

Edit:Ahhhh now figured out...your quest is bugged if you find garcia first in game all game brokes and you cant advance anymore the only solution will be to leave maracai bay last one otherwise you are stuck.
