How to Get to Third Sea
The Third Sea (Sea 3) is the current endgame. It introduces the strongest weapons (3SS V2, Gryphon, Dual Dark Blade), Golden Staff V2, and access to the final quest rewards.
Requirements
- Must already be in Second Sea
- Level 4,200
Step-by-Step
- Reach Level 4,200 while in Second Sea
- Find the Gatekeeper NPC
- The Gatekeeper will test your resolve — this triggers a boss fight against Shanks
- Shanks Boss Fight:
- Shanks has two phases
- Phase 1: standard combat, dodge his attacks and deal damage
- Phase 2: at 25% HP, a cutscene triggers — "Impressive. Didn't expect someone like you to push me this far."
- Shanks enters his second form with increased damage
- You do NOT need to kill him — get him to low HP and survive
- After the fight, Shanks says "We will cross paths again in the Third Sea"
- The Gatekeeper teleports you to the Third Sea
