Sea 2 unlock
How Map Pieces work
  • 7 Map Pieces needed to unlock Sea 2
  • Each piece has a fixed pool of bosses — kill any one in the pool to roll for that piece
  • Drops are random; expect multiple kills per piece
  • Luck stat does NOT affect Map Piece drops — focus on damage to kill faster
  • Open-world bosses only — Boss Rush, Infinite Tower, and Dungeon bosses do not drop Map Pieces
  • At 6/7, talk to the Cartographer on World Island to see which piece you’re missing
Check off pieces as you collect them — progress saves automatically.
