サードシーアップデート概要

Big content drop that reworks mid-to-late game progression. The patch adds a new Mythical Devil Fruit, a race V2 upgrade, two weapon trees, high-tier crafted accessories, and a dedicated PvP companion system.

主要ハブ：

• Third Sea starter island — race V2 quest chain and Sword Shrine access
• New grid sectors — Sea Beast encounters and rare mob farming
• Blacksmith NPC — S-Tier weapon and accessory crafting

報酬s favor mastery and exploration grind. Progression paths are clear, but you'll need specific materials and consistent farming time.

新モンスター＆ボス

The Third Sea expansion fills the new grid sectors with high-threat open-world encounters. Sea Beast fights are the headline PvE loop — they gate Sea Beast Hammer drops, Blacksmith crafting mats, and accessory V2 recipes. Rare mobs in the same sectors supply supplemental loot for endgame gear.

Farming priorities:

• Sea Beast encounters — roam Third Sea grid sectors; primary source for hammer drops and Sea Beast crafting materials
• Rare grid mobs — supplemental drops for Sea Beast Helmet V2 and Sea Beast Armor V2 recipes
• Super Boss routes — pair with the Super Bosses Database and World Map when planning long farming sessions

Okuchiの実 — 神話悪魔の実

Okuchi is a Mythical-class fruit that completely changes your movement and combat animations. Running, dashing, and basic attack strings are replaced with unique beastly animations. The headline feature is a fully animated Awakened Beast Form that changes your hitbox and ability properties.

データベース注記： Okuchi is listed under the Mythical tier with placement pending — see the fruit detail page for live skill data and unlock requirements.

基本形態スキル

覚醒獣形態

Pop Awakened Beast Form and your model scales up, hitbox expands, and all ability damage plus AoE radius get boosted. スキルs evolve:

For full passive lists, gameplay tags, and database cross-links, see the Okuchi detail page. Pair with our Endgame Progression Guide for broader Mythical fruit context.

Fishborne V2 種族アップグレード

Fishborne (also known in-game as Fishman) receives a direct V2 upgrade that replaces body fins with a full fish tail model. Unlock via a specific quest chain on the Third Sea starter island.

主要V2パッシブ

Fishborne V2 is the premier race for aquatic mobility and survival. No other race matches its water-adjacent PvP and exploration utility in the current meta.

新武器 — シービーストハンマーと三刀流

Two new weapon sets anchor Third Sea combat builds. Full stat breakdowns live in the Swords Database.

シービーストハンマー

Sea Beast Hammer is a Heavy Blunt weapon that drops from Sea Beast encounters in Third Sea grid sectors.

Best for slow, high-damage, crowd-control playstyles. Farm Sea Beasts in the new grid sectors until the drop lands — see the Weapons Procurement Guide for broader drop context.

三刀流（3SS）

3SS ships in two versions:

3SS V1 — Unlocked at the Sword Shrine on the Third Sea starter island. Requirements:

• Shusui, Enma, and Zerit swords
• Each sword at 300 mastery

3SS V2 — S-Tier upgrade crafted at the Blacksmith NPC. Recipe: 3SS V1 + Ancient Blade Relic + standard Third Sea components. Features custom M1 tracking and three skills:

High-skill, high-reward path — budget mastery time across all three component swords before attempting the Shrine unlock.

高ティアアクセサリー — シービーストヘルメットV2＆アーマーV2

Top-tier accessories from this update. Both are crafted exclusively at the Blacksmith NPC using Third Sea materials — Sea Beast drops and rare mob loot from new grid sectors. Browse full stats in the Accessories Database.

Crafting both is a priority for any endgame build worth its salt. Pair with Fishborne V2 for maximum water-zone survivability.

デモンサモナー仲間 — PvPシステム

The Demon Summoner is a specialized PvP tool — not a standard NPC summon.

解放条件： Reach 25,000,000 Bounty to receive a special high-tier item token.

Once summoned, it auto-locks onto and attacks enemy players flagged for PvP. It ignores standard NPCs entirely. Functions as a localized deployment asset for tracking during player combat.

おすすめ： Bounty hunters and open-world PvP — consistent pressure and damage on a single target. If you're on the receiving end, treat it as a priority delete target.
