Ice Core is one of the most important materials in the latest Sailor Piece update. While many players are focused on unlocking the new Frost Empress weapon, they often discover that an Ice Core is required later when trying to unlock the weapon’s F Move Mastery. If you’re wondering where to find Ice Core and the fastest way to farm it, this guide covers everything you need to know.

What Is Ice Core Used For?
Ice Core is a special crafting material used for the Frost Empress F Move Mastery route. Unlocking the base Frost Empress weapon is not enough if you want access to the weapon’s full power. To unlock Frost Empress Mastery, players need:
- Frost Empress Weapon
- Kuchiki Clan
- 1 Ice Core
- 25 Soul Fragments
- 10 Bankai Essences
Without an Ice Core, you won’t be able to complete the mastery requirements and unlock the powerful F Move skill. The only known way to obtain Ice Core is by defeating the Ice Queen Boss. This boss can be found on Boss Island. Once you arrive, look for the Ice Queen and start farming the encounter until the item drops. Since Ice Core is a boss drop, there is no guarantee that it will appear after every defeat. Some players may get it quickly, while others may need multiple runs before seeing the item.
Where to Find Ice Queen Boss
The Ice Queen Boss is located on Boss Island and serves as the primary source of Ice Core. If you have previously farmed Ice Queen for other materials, check your inventory before starting the grind. Some players may already have an Ice Core stored without realizing it. For players who do not have one, repeated boss farming will be necessary.
Best Way to Farm Ice Core
Because Ice Core comes from a boss drop, efficiency is important. Here are a few tips to speed up the process:
- Focus entirely on Ice Queen until the item drops.
- Join other players to defeat the boss faster.
- Use your strongest build to reduce farming time.
- Stay near the boss spawn location to avoid missing respawns.
- Check your inventory regularly to make sure the item has not already dropped.
Farming in a group is usually the fastest option, especially if your character does not have enough damage to defeat the boss quickly on their own.
Ice Core and Frost Empress Progression
Many players unlock Frost Empress and immediately stop farming, only to realize they still need additional materials for mastery. Ice Core is one of the most important requirements in this second stage of progression.
A good strategy is to plan ahead. If you know you want the Frost Empress F Move, start farming Ice Queen early while also collecting Soul Fragments and Bankai Essences from the Frost Empress World Boss. This approach can save a lot of time later.
Ice Core may only require a single drop, but it is a mandatory material for unlocking Frost Empress F Move Mastery in Sailor Piece. The item can be obtained from the Ice Queen Boss on Boss Island, making that boss a key target for players working toward the full Frost Empress upgrade path.
Once you obtain an Ice Core, combine it with the required Soul Fragments, Bankai Essences, Frost Empress weapon, and Kuchiki Clan to complete the mastery requirements and unlock the weapon’s strongest form.
