You can’t access Sea 2 without collecting all seven Sailor Piece Map Pieces. Each piece requires the defeat of a specified boss in Sailor Piece. Once you unlock Sea 2, you can start rolling for Bloodlines, which boost your stats.

Sailor Piece Map Pieces

To unlock Sea 2 in Sailor Piece, one of the main requirements is to find Map Pieces. Seven of them, to be exact. This part of the quest comes after you find the two Ancient Fragments, and cannot be found before completing that task.

If you’re looking for how to get each Map Piece, you’ve probably already met the first round of requirements, which are to reach level 12,500 and ascend to Ascension Level 5.

How to Get All Map Pieces

Each Map Piece has the chance to drop from the bosses specified below. The drop chance is significantly low, mind you. All Map Pieces can drop from two different bosses, apart from Map Piece 6, which drops from three bosses.

Unlocking Sea 2

Once you obtain all 7 Map Pieces, you unlock access to Sea 2. To get there, you need to teleport to World Island. From there, walk towards the giant glowing portal next to the Sea Traveler NPC, also known as the World Island Door, in the tree trunk, to be prompted to ‘Enter Sea 2’.

Now that you’ve unlocked Sea 2, you can visit the new map whenever you want.
