In Sailor Piece, the Frozen Brand is a crucial Mythical item primarily used to purchase the Ice Queen sword and unlock its powerful F move. Players can obtain the Frozen Brand by defeating the Ice Queen boss, which can be summoned on Boss Island using Frost Relics, Gems, and Money. The Ice Queen can be fought at four difficulty levels: Normal, Medium, Hard, and Extreme. The drop rate for the Frozen Brand is 1.20% on Normal difficulty and increases to 1.85% on Extreme difficulty. Additionally, players can acquire Frozen Brands through trading with others. To enhance drop chances, players should focus on increasing their Luck% using various game upgrades. Collecting Frozen Brands requires players to stay on Boss Island, and activating the spawn crystal is advisable to ensure quick respawns after defeats.
