Three Sword Style V2 is the upgraded form of Haze Seas’ triple-blade weapon, and it sits at the end of a long chain that runs through all three seas. You cannot buy it or farm it from a single boss. You build the base version first, grind it to full Mastery, then turn it into V2 at a Sea 3 forge using rare drops.
Quick answer: Take Three Sword Style V1 to 300 Mastery, gather 5 Ancient Blade Relics, then craft 3SS V2 at Doran the Forge in Sea 3.

Everything you need for 3SS V2
The final craft is short, but the prerequisites behind it are not. You need a fully mastered 3SS V1, and that alone forces you to collect and master three separate swords first. Here is the full dependency chain in one place.
| Requirement | Detail |
|---|---|
| 3SS V1 | Must be owned and mastered before the upgrade unlocks |
| Mastery | 300 Mastery on 3SS V1 |
| Material | 5 Ancient Blade Relics |
| Location | Doran the Forge, Sea 3 |
To reach 3SS V1 in the first place, you need Zenith, Shusui, and Enma, each pushed to 300 Mastery. Those three swords are scattered across Sea 1 and Sea 2, so plan your route before committing to the grind.

These are the three keys to 3SS V1. Two are farmed from Sea 2 bosses and one drops in Sea 1, and their drop rates vary a lot, so expect Enma and Shusui to take repeated attempts.
| Sword | Source | Where |
|---|---|---|
| Shusui | 5% drop from Ryummy | Thriller Boat (top of the castle) |
| Zenith | 100% drop from the Zenith Boss | Shadow Island, inside the cave at the bottom of the island |
| Enma | 10% drop from the Enma Boss | Flower Capital, inside the mansion at the top of the stairs |
Zenith is the reliable one. The Zenith Boss only appears during the storm event on Shadow Island, signalled by a red on-screen warning that a violent storm has taken over the sea. That event returns roughly every 2 hours and 35 minutes, and when you beat the boss, the sword is a guaranteed drop.
Note: Do not sell or drop these three swords after you collect them. All three must stay in your inventory and reach 300 Mastery for the shrine to accept them.

Build 3SS V1 at the Shrine of Three Swords
[E] Shrine of Three Swords / Interact prompt appears, then press E. This converts your three mastered swords into Three Sword Style V1.
Upgrade to 3SS V2 at Doran the Forge
With 3SS V1 in hand, the upgrade happens entirely in Sea 3. Doran the Forge is the crafting station that turns high-Mastery swords and rare relics into their strongest forms.

3SS V2 moveset and how to confirm it worked
You know the craft succeeded when Three Sword Style V2 appears in your inventory as a fresh weapon at 0 Mastery, replacing the V1 you handed over. Equip it and check the moves, which unlock as its Mastery climbs.
| Key | Move | Unlocks at |
|---|---|---|
| Z | Soaring Phoenix | Mastery 0 |
| X | Purgatory Descent | Mastery 25 |
| C | Three Thousand Skies | Mastery 50 |
If the forge refuses the craft, the cause is almost always one of two things. Either your 3SS V1 has not reached 300 Mastery yet, or you are short of the 5 Ancient Blade Relics. Fix whichever is missing, and the upgrade becomes available. Once V2 is equipped, keep fighting to unlock Purgatory Descent and Three Thousand Skies and bring the sword up to its full potential.
