Divine Grail in Sailor Piece is a Legendary item that you need to summon the Gilgamesh Boss on the Boss Island. If you want to farm the Gilgamesh accessories and the materials required to obtain the Gilgamesh fighting style, you’ll need to grind the boss. And, for that, you’ll need as many Divine Grails as you can get.
How to Get the Divine Grail in Sailor Piece

Divine Grail is a craftable item in Sailor Piece. To craft it, you need to talk to the Divine Grail Crafter NPC on Boss Island. When you teleport to the Boss Island, go to the centre arena and then climb onto the giant hand statue on your left to find the NPC.
You’ll need 3x Broken Sword to craft 1x Divine Grail. So, before you head over to the Divine Grail Crafter NPC, I suggest you farm as many Broken Swords as possible. Read on to learn how to easily farm Broken Sword in Sailor Piece.
How to Get Broken Sword in Sailor Piece
The Broken Sword is an Epic item that can only be obtained as a drop from mobs and mob bosses that use a sword. We don’t know the exact drop chances, but they are fairly rare. So, you will have to grind a little to farm Broken Swords.
Here’s a list of all the mobs and bosses that use swords so you can farm the right enemies:
- Desert Bandit (mob) on Desert Island. (Level 750+)
- Desert Boss (mob boss) on Desert Island. (Level 1000+)
- Frost Rogue (mob) on Snow Island. (Level 1500+)
- Winter Warden (mob boss) on Desert Island. (Level 2000+)
- Sorcerer Student (mob) on Shibuya Station. (Level 3000+)
- Slime Warrior (mob) on Slime Island. (Level 8000+)
If you want to farm Broken Swords quickly, I suggest you grind the sword-bearing mobs. Each NPC in the mob has a chance to drop the Broken Sword. That means there’s a chance you can get 4 to 5 Broken Swords by clearing a mob. On the other hand, killing a mob will only give you 1 Broken Sword.
Also, the stronger NPCs have a higher chance of dropping Broken Swords. So, Slime Warrior NPCs will almost always drop Broken Swords. Weaker mobs and bosses like Desert Bandit and Winter Warden will have a lower drop chance.

Once you have enough Broken Sword, go back to the Divine Grail Crafter NPC at Boss Island and craft as many Divine Grails as possible. You can then talk to the Boss Summoner NPC on the same island to spawn the Gilgamesh Boss.
