Swords

Sailor Piece has 19 swords ranging from the Katana on Starter Island to endgame weapons that require rare boss materials, specific titles, and tens of thousands of gems. Most swords are purchased from NPC sellers or unlocked through trainer questlines, and several form evolution chains where one sword upgrades into another. Sea 2 added the Dragon Goddess, a rare drop from open-sea bosses.

Evolution Chains

Three swords in Sailor Piece are built by upgrading a base weapon rather than purchasing from an NPC:

• Jinwoo (Sailor Island) upgrades into Shadow Monarch (Dungeon Island)
• Shadow (Dungeon Island) upgrades into Atomic (Lawless Island)
• Manipulator Sword (Hollow Island) upgrades into True Aizen (Soul Dominion)

If you plan to pursue an evolution weapon, keep the base sword in your inventory. You need it to complete the upgrade.

Blessing Upgrades

Every sword can be upgraded from B1 to B10 at the Blessing NPC on Shibuya Station. A fully blessed weapon gains +25% Damage, +5% Crit Chance, and +8% Crit Damage. The materials are Wood, Iron, Obsidian, Mythril, and Adamantite, with costs increasing at higher levels. B10 requires 250 Wood, 125 Iron, 85 Obsidian, 40 Mythril, and 15 Adamantite total.
