Sailor Piece Islands Guide: All Locations & Activities
Every island in Sailor Piece with level requirements, bosses, activities, ancient puzzle piece locations, and Hogyoku Fragment spots. Updated for the March 2026 Huge Update.
Early Islands
7 islandsSailor Island
The central hub of the game. Sailor Island is where players find merchants, NPCs, currency exchange, the Fruit Dealer, the Alucard boss, and the Boss Rush portal. Every player returns here frequently.
Starter Island
The tutorial zone where all new players begin their journey in Sailor Piece. It is a safe, enemy-free island designed to introduce core mechanics: movement, combat, quests, and weapon purchasing. Starter Island also holds the first of 6 ancient puzzle pieces required to unlock the Rune Dungeon.
Jungle Island
An island blanketed in dense ancient vegetation, Jungle Island marks the transition from beginner content to the mid-game. Players who reach level 250 are expected to leave Starter Island and Sailor Island and begin quest chains here. The island is also home to the second of 6 ancient puzzle pieces, hidden in a rock pile on the left side — you must jump over the sandy path to reach it.
Desert Island
A scorching sandy island that serves as one of the most important early progression stops. Desert Island is home to the Observation Haki Master NPC — learning Observation Haki costs 250,000 Cash and 300 Gems and is required to see enemy health bars and dodge certain attacks. The island also contains ancient puzzle piece #3 on the opposite side from spawn.
Dungeon Island
The gateway to the Rune Dungeon system. Players must be level 5000+, complete the Dungeon Master NPC quest chain, and collect all 6 ancient puzzle pieces before gaining access. High-risk, high-reward.
Snow Island
A frozen mountain island that is one of the most content-rich stops in the early-to-mid game. Snow Island houses the Haki Master NPC for Armament Haki (250,000 Cash + 250 Gems + a prerequisite quest), making it a required stop for all players. Beyond Haki, the island also features the Artifact system, weapon upgrade station, Skill Tree NPC, and contains both ancient puzzle piece #4 and Hogyoku Fragment #1 — the first of six fragments needed to access Soul Society.
Christmas Island
A limited-time seasonal island decorated with Christmas themes and snow effects, accessible to players of any level during the Christmas event period. The main attraction is the Ragna boss (12.5M HP), which drops exclusive accessories: Wyrm Band, Black Frost, and Silver Requiem. These drops are only available while the event is active, making Christmas Island one of the most popular seasonal destinations.
Mid Islands
3 islandsBoss Island
The dedicated boss summoning hub. Players summon Saber, Ichigo, Gilgamesh, Qin Shi, and Blessed Maiden here using Boss Keys and currency. Also contains a crafting station and the Gilgamesh NPC for his fighting style.

A cursed Tokyo-themed island housing three open-world bosses (Yuji, Gojo, Sukuna) and the Conqueror Haki Trainer. Also features multiple anime training NPCs and the Enchant NPC for accessory enchanting. Contains puzzle piece #5.
Hueco Mundo
The void world island at level 5000. Home to the Aizen open-world boss (25M HP, 100% Haki Color Reroll drop rate) and specialized training merchants. Contains puzzle piece #6.
