How to Unlock Sea 2
- 1
Reach the late-game Sea 1 quest gate
You'll need to be deep into Sea 1 progression with mid-to-late stats before farming becomes efficient. NPC kills below the recommended level deal reduced damage.
- 2
Farm Ancient Fragments (×2)
Fragments drop from NPCs across 20 locations on 12 Sea 1 islands. After the April 21 hotfix, drop rates were buffed and a pity system added — guaranteed drop after 25 kills if you've had no fragment.
- 3
Travel to World Island
World Island is the Sea 1 entry island for Sea 2. After the April 23 fix, auto-rejoin now correctly detects Sea 2 servers — new private servers join Sea 2 directly without manual selection.
- 4
Use the Door to enter Sea 2
Once Sea 2 is unlocked, the Door at World Island lets you travel between Sea 1 and Sea 2 freely. The April 23 hotfix fixed a “stuck in Sea 2” bug.

15–150 members, 6 upgrade tiers, member cap and bonus stat increases.

Gacha lineage system with permanent stat bonuses. Top tiers: Primordial, Astral.
