Divine Grail is a Legendary item in Sailor Piece, and the current unlock method is straightforward once you know the requirement.
Quick answer: Get 3 Broken Swords, then use the Divine Grail Crafter NPC to craft Divine Grail.
Divine Grail crafting requirement
| Item | Rarity | Requirement |
|---|---|---|
| Divine Grail | Legendary | Craft at the Divine Grail Crafter NPC using 3 Broken Swords |
| Broken Sword | Epic | Drops from any enemy |
How to craft Divine Grail
Step 1: Farm enemies until you collect 3 Broken Swords. Broken Sword is an Epic item, but it can drop from any enemy, so the main requirement is repetition rather than a specific boss.
Step 2: Go to the Divine Grail Crafter NPC. You need that NPC specifically, not a general crafting station.
Step 3: Interact with the NPC and craft the Divine Grail. If the craft is available, the three Broken Swords are consumed, and the item is created immediately.
How to know it worked
The craft is complete when Divine Grail appears in your inventory after the interaction with the Divine Grail Crafter NPC. Your Broken Swords should no longer be there once the recipe goes through.
What stops Divine Grail from crafting
| Problem | What it means |
|---|---|
| You have fewer than 3 Broken Swords | The recipe cannot be completed yet |
| You are at the wrong NPC | Divine Grail only crafts at the Divine Grail Crafter NPC |
| You are farming a specific boss for Broken Sword | That is unnecessary, since Broken Sword can drop from any enemy |
What matters most when farming Broken Swords
The only material tied to Divine Grail is Broken Sword, and Broken Sword can come from any enemy. That means the fastest path is usually whichever enemies you can clear consistently and quickly, because the recipe does not require a named boss drop.
Divine Grail itself is classified as Legendary, while Broken Sword is classified as Epic. Once you hit the three-sword requirement, the process shifts from farming to a single NPC interaction.
If you are trying to finish this as fast as possible, the whole loop is simple: kill enemies until you have 3 Broken Swords, find the Divine Grail Crafter NPC, and craft the item there.
