A Tattered Parchment can be found randomly in a Barrel. Once picked up, they add one map to the map wheel of every pirate in a crew. This map can be a Treasure Map, Riddle Map, or Bounty Map. Quests from bottles do not have to be completed in order to complete a crew's voyage. The parchment serves similarly to the Mysterious Journal or a Message in a Bottle.
