Frost Relic is an item in Roblox Sailor Piece that is primarily used to summon a boss and obtain a special sword. Specifically, it allows you to spawn the Ice Queen boss in the arena for 1v1 or multiplayer encounters to get the Ice Queen weapon. Like other relics, you’ll need to farm NPCs to acquire it.
Players can get Frost Relic by beating mini-mobs (regular enemies) native to various islands, but since its drop rate is extremely low, they will need to increase their luck stats and then try grinding for this item. For those looking to collect Frost Relics and snag the Ice Queen Sword quickly in Sailor Piece, check out our detailed guide below.

Find the top picks in Sailor Piece with this tier list designed for early, mid, and endgame builds.
How to Get Frost Relic in Sailor Piece
As mentioned above, all fighter NPCs in the game can drop Frost Relics, but the best way to get them in Sailor Piece is by defeating the Arena Fighters located on Lawless Island. Thankfully, this area is open to everyone, unlike Soul Dominion, which requires completing the Hogyoku quest.
These enemies have a massive 12,000 HP, so you should be at or above that level to deal with them effectively. Make sure to reach that level first before attempting to farm here. This will also help increase your health pool, making you more durable against the Ice Queen boss.
If you’re in the early to mid-game, you can also fight the following enemies:
- Curse (Lv. 7,000) on Shinjuku Island
- Slime Warrior (Lv. 8,000) on Slime Island
- Academy Teacher (Lv. 9,000) on Academy Island
- Swordsman (Lv. 10,000) on Judgment Island
- Quincy (Lv. 10,750) in Soul Dominion (Locked)
- Ninja (Lv. 11,500) on Ninja Island
However, taking down Arena Fighters remains the best option, especially if you have auto-farming abilities like Gilgamesh. Just activate its V skill and continuously beat Arena Fighters to snag many Frost Relics over time.
Since Frost Relic drops heavily rely on luck, you can improve your chances by equipping Luckborn (35% luck boost) or Kitsune (25% luck boost), along with the Monarch and Eminence clans, to maximize your luck and increase the chances of getting duplicate relics. Upper and Alter also work.
Players can also equip luck-based titles like Destiny Marked and Celestial Favor, which can increase their odds of obtaining Frost Relics from NPCs by 40 to 50%.

How to Get Ice Queen Sword in Sailor Piece
Spawn the Ice Queen Boss
Once you have enough Frost Relics, you can challenge the Ice Queen boss. Just follow these steps:
- Go to the portal and teleport to Boss Island (the eighth one on the map).
- Engage with the Boss Summoner NPC and go to the Ice Queen boss banner.
- Select your difficulty and click “Spawn.”
This will make the Ice Queen appear in the Chessboard Arena. She has 1,650,000,000 HP, so make sure to maximize your DPS, health, and Melee/Sword damage. You can summon her in four difficulty modes:
- Normal: 1 Frost Relic + 750,000 Money + 750 Gems
- Medium: 2 Frost Relics + 1,000,000 Money + 1,000 Gems
- Hard: 3 Frost Relics + 1,250,000 Money + 1,250 Gems
- Extreme: 4 Frost Relics + 1,850,000 Money + 1,850 Gems
Higher difficulty increases the drop rate for rare items needed to craft the Ice Queen Sword, so plan accordingly.
Gather All Materials for the Ice Queen Sword
Next, you’ll need the following things:
- 1 Ice Core (0.26% drop rate from Ice Queen boss)
- 4 Frozen Brand (0.60% drop rate from Ice Queen boss)
- 9 Glacier Remnant (2.65% drop rate from Ice Queen boss)
- 17 Battle Shard (8% drop rate from Ice Queen boss)
- Frost Empress Title (Beat the Ice Queen boss)
- 25 Frost Relics
- 40,000 Gems
After you have everything, head northeast on Boss Island and purchase the sword from the Ice Queen NPC.
Unlock Ice Queen Weapon Mastery (Optional)
Players can also craft the Ice Queen F-Move Mastery, a powerful ability that can only be obtained through crafting. To do so:
- Enter Boss Island and climb up the giant concrete hand, where the King of Heroes NPC is located.
- Click “E” when near the fighter NPC to start crafting.
You must have the following items to complete crafting:
