Gilgamesh, the King of Heroes, is one of the strongest endgame fighting styles in Sailor Piece, built around wide beam attacks, area control, and heavy burst damage. Unlocking it is a grind that runs through a single boss, a stack of rare drops, and a large currency payment, so the fastest route is mostly about preparing materials in bulk before you start fighting.
Quick answer: Craft a Divine Grail from 3 Broken Swords, summon and defeat the Gilgamesh boss on Boss Island repeatedly until you collect 1 Golden King Title, 12 Throne Remnant, 6 Ancient Shard, 3 Golden Essence, and 1 Phantasm Core, then deliver them with 25,000,000 Money and 22,500 Gems to the Gilgamesh Trainer (King of Heroes NPC) on Boss Island to unlock the fighting style.
Gilgamesh unlock requirements in Sailor Piece
Every rare material for the unlock comes from the Gilgamesh boss, so the bottleneck is drop luck, not quest steps. Gather everything below before you visit the trainer. The full unlock cost is listed in one place here so you can budget runs.
| Requirement | Amount |
|---|---|
| Golden King Title | 1 |
| Throne Remnant | 12 |
| Ancient Shard | 6 |
| Golden Essence | 3 |
| Phantasm Core | 1 |
| Money | 25,000,000 |
| Gems | 22,500 |
Craft the Divine Grail and summon the Gilgamesh boss
Note: Defeating the boss once does not guarantee the Golden King Title. Expect to repeat the fight many times, with around 21 clears commonly needed before the title reliably drops.
Gilgamesh boss drops and drop rates
Each kill grants guaranteed rewards plus a chance at the rare materials you need. The Phantasm Core is the rarest item in the table, so it usually dictates how long the grind takes.
| Reward | Type | Drop rate |
|---|---|---|
| 225 Gems | Guaranteed | 100% |
| EXP (scales with level) | Guaranteed | 100% |
| Gilgamesh Armor | Rare drop | — |
| Throne Remnant | Rare drop | 11.5%–20% |
| Ancient Shard | Rare drop | 4.5%–6.5% |
| Golden Essence | Rare drop | 1.5%–2.5% |
| Golden King Title | Rare drop | 1%–1.5% |
| Phantasm Core | Rare drop | 0.5%–0.75% |
Farm Gilgamesh faster
Because the unlock depends on low-chance drops, run efficiency matters more than picking the hardest mode. The goal is more clears per hour, not harder fights.
- Pre-craft Divine Grails in bulk so you can summon back-to-back.
- Prioritize fast clears over higher difficulty modes.
- Raise luck stats or use luck boosts to improve rare drop odds.
- Fight in a team to cut kill time per boss.
Unlock the Gilgamesh fighting style
Once you have all five rare materials and the currency, go to the Gilgamesh Trainer, also called the King of Heroes NPC, on Boss Island. Hand over the materials along with 25,000,000 Money and 22,500 Gems to unlock the style. You know it worked when the King of Heroes fighting style becomes equippable on your character.
The base moveset is built for both farming and boss damage:
| Key | Move |
|---|---|
| Z | Fires two light beams |
| X | Traps enemies and strikes them with beams |
| C | Wide cone slash |
| V | Golden circles rain down beams over an area |
| F | Large fire blast from above (locked by default) |
Unlock the Gilgamesh F move with the Babylon Key
The F move, the large overhead fire blast, is the highest-damage ability in the kit and stays locked until you craft and use a Babylon Key. Craft it at the Babylon Key NPC, which sits near the Divine Grail NPC, and make sure you have the Servant Race equipped before crafting.
| Babylon Key requirement | Amount |
|---|---|
| Servant Race (equipped) | Required |
| Broken Swords | 100 |
| Golden Essence | 5 |
| Phantasm Core | 2 |
Once you craft and use the Babylon Key, the F move is permanently available on the style. Plan ahead, since the extra Golden Essence and Phantasm Cores for the key come from the same boss as the unlock materials, so banking spares during your farming runs saves a second grind.
The whole process rewards preparation over brute force. Stack Divine Grails, push your luck stats, run the boss with a group, and hold onto extra Golden Essence and Phantasm Cores so the fighting style unlock and the Babylon Key both come together in one stretch of farming.
