Sailor Piece Items

There are 197 items split across seven categories: keys (16), currencies (12), runes (11), chests (8), materials (7), artifacts (7), and relics (6). Each category serves a different role — keys unlock game modes, currencies fund upgrades, and runes directly boost your combat stats.

The Secret Chest is the rarest standard chest with only a 0.02% drop chance from any NPC in the game. It can also be obtained through promotional codes. It grants rare items, Gems, and Coins when opened, making it one of the most exciting drops you can find.

Keys are used to enter specific game modes or summon bosses. Most epic keys like the Dungeon Key and Boss Key drop from regular NPCs or quests, while legendary keys are tougher — for example, the Reaper Key has just a 0.1% drop rate from Ghoul Members on Isolation Island. The Guild Key (secret rarity) is extremely rare, dropping only from Sea 2 NPCs.

Runes are powerful passive items dropped in the Rune Dungeon that permanently boost your character's stats. For example, the Blood Rune starts at 65% bleed damage over 5 seconds and grows to 97% at level 60, while the Destruction Rune scales from 1.25x to 1.37x damage. Leveling runes requires repeated Rune Dungeon runs — their drop rates range from 4% (Guardian Rune) to 2% (mythical runes).

Enchanting at Shibuya Station uses materials from common Wood (5-7% from any NPC) up to mythical Adamantite (Snow Island and above) and Diamond. Mid-tier materials like Obsidian drop 1-2% from Desert Island enemies and above, while Iron (2-4%) drops from most islands except Starter Island. Higher-tier materials come from harder zones, so progressing through the seas naturally unlocks better enchanting options.
