Sea 2 Unlock Guide
Sea 2 unlock route
Sea 2 is the update layer added on top of Sea 1. The level cap jumps to 20,000, six new islands open up, and several new progression systems come with the update. You also get new melee styles, new swords, a Raid system on Blue Planet, and a global damage reduction applied to every Sea 2 enemy.
How to Unlock Sea 2
The unlock is a Sea 1 questline. Start on World Island, where the Cartographer gives you the Lost Fragments quest.
| Step | Requirement | Location |
|---|---|---|
| 1 | Start Lost Fragments quest | Cartographer, World Island |
| 2 | Collect 2 Ancient Fragments | Sea 1 islands |
| 3 | Farm 7 Map Pieces | Sea 1 bosses |
| 4 | Return to Cartographer | World Island |
Ancient Fragment Timing
Fragments rotate through a fixed pool of spawn points on Sea 1 islands. Only 2 are needed for the unlock, but the spawns rotate, so learning more than two locations saves time.
| Field | Value |
|---|---|
| Respawn interval | 1 minute 30 seconds |
| Despawn after spawn | 5 minutes |
| Spawn pool size | 20 |
| Required for unlock | 2 |

Map Piece Boss Pools
After the fragments come 7 Map Pieces. Each map has a boss pool you can roll from, and the order you complete them is up to you.
- 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.
- 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.
