The Broken Sword is an Epic-rarity crafting material in Sailor Piece on Roblox, and it trips up a lot of players because it doesn't follow the usual loot rules. You won't find it in chests, and it won't appear in boss reward pools. The only way to collect Broken Swords is by killing specific sword-wielding enemies scattered across the game's islands.
Quick answer: Defeat Slime Warriors on Slime Island repeatedly — they yield the highest Broken Sword drop rate of any enemy in the game.
Which Enemies Drop Broken Swords
Broken Swords exclusively drop from enemies that carry swords. Not every NPC on every island qualifies, so grinding the wrong mobs will waste your time. The four most reliable sources are listed below.
| Enemy | Location | Notes |
|---|---|---|
| Slime Warrior | Slime Island | Highest observed drop rate; best overall farm spot |
| Sorcerer Student | Shibuya Station | Solid alternative for mid-level players |
| Swordsman | Judgement Island | Good option if your XP level matches the zone |
| Ninja | Ninja Island | Viable but slightly less consistent |
Enemies on Desert Island and Snow Island also wield swords, but their Broken Sword drop rates are noticeably lower. Stick to the four locations above for efficient farming.
Fastest Way to Farm Broken Swords
Teleport to Slime Island and start clearing Slime Warriors. The key insight is that kill speed matters more than enemy level. Defeating enemies quickly — ideally in as few hits as possible — appears to improve the chance of receiving a Broken Sword drop. Fighting higher-level enemies does not increase your odds.
To maximize kill speed, equip a high-damage sword. Shadow Monarch is currently the strongest sword in Sailor Piece, with 999 mastery and fast attack animations. If you don't have it, True Aizen, Yamato, or Escanor are strong alternatives. Pair your weapon with an optimized fighting style for even faster clears.
Beyond raw damage, you can push your luck and output higher by investing in the skill tree, upgrading through the Power System, and equipping strong Spec Passives. Every bit of extra damage shortens each kill, which translates directly into more Broken Swords per hour.
What Broken Swords Are Used For
Broken Swords are a crafting ingredient for two important items, both of which feed into the King of Heroes content path.
| Crafted Item | Rarity | Recipe | NPC |
|---|---|---|---|
| Divine Grail | Legendary | 3× Broken Sword | Divine Grail Crafter |
| Babylon Key | Mythical | 100× Broken Sword, 5× Golden Essence, 2× Phantasm Core | Babylon Key Crafter |
The Divine Grail is the more accessible craft — just three Broken Swords per grail. You use Divine Grails to summon the King of Heroes boss, which drops materials needed to unlock the King of Heroes fighting style and its F move. The Babylon Key is a much heavier investment at 100 Broken Swords plus additional Legendary and Mythical materials, so plan your farming sessions accordingly.
Common Mistakes to Avoid
The biggest time sink is farming enemies that don't carry swords. Because the Broken Sword is classified as an Epic drop from "any enemy" in some item lists, players often assume every NPC can drop it. In practice, only sword-wielding mobs produce the item. If you're killing ranged or unarmed enemies and seeing zero Broken Swords, that's why.
Another common error is opening chests and expecting Broken Swords to appear. They never drop from loot chests or random boss reward pools — only from direct enemy kills.
Broken Swords are straightforward to farm once you know the rules. Head to Slime Island, build for fast kills, and stack up your inventory. Whether you're crafting Divine Grails for the King of Heroes boss fight or saving toward a Babylon Key, the grind is the same — just keep clearing Slime Warriors until you have what you need.
