Gilgamesh is one of the most powerful Mythical-rarity melee fighting styles in Sailor Piece, introduced during the Fate Update on February 18, 2026. Inspired by the King of Heroes from Fate/Grand Order, this style delivers massive AoE damage, high DPS, and crowd control, making it a top-tier pick for late-game farming and boss fights. Here’s exactly how to unlock it, step by step.
| Key Info | Details |
|---|---|
| Rarity | Mythical |
| Location | Boss Island (NPC above the stone hand sculpture) |
| Boss Summon Cost | 1 Divine Grail + 500k Money + 500 Gems |
| Style Cost | 5 items + $25M + 22,500 Gems |
| F Move Unlock | Babylon Key (crafted separately) |
| Update Added | Fate Update β February 18, 2026 |
Before you can fight the Gilgamesh boss, you need a Divine Grail. Head to Boss Island and find the Divine Grail Crafter NPC (located near the Babylon Key Crafter NPC).
To craft one Divine Grail, collect:
Interact with the NPC to craft the Divine Grail.
Pro Tip: Farm Slime Warriors in a group to speed up Broken Sword drops. The drop rate is low, so expect to kill dozens before getting two.
Take your Divine Grail + 500,000 Money + 500 Gems to the Boss Spawner on Boss Island. This summons the Gilgamesh boss, who has up to 5 billion HP on Extreme difficulty.
Defeat him repeatedly to collect all required fighting style materials:
| Item | Drop Rate |
|---|---|
| Golden King Title | 1% β 1.5% |
| 12x Throne Remnant | 11.5% β 20% |
| 6x Ancient Shard | 4.5% β 6.5% |
| 3x Golden Essence | 1.5% β 2.5% |
| 1x Phantasm Core | 0.5% β 0.75% |
The Golden King Title and Phantasm Core are the hardest drops, expect 20β50+ boss kills before you get everything. Check our Sailor Piece Bosses Guide to build the strongest setup before attempting this boss.
Pro Tip: Run Extreme difficulty for the best drop rates. Equip the Fortune Rune to boost your luck. Use the Sailor Piece Runes Guide to farm runes efficiently.
Once you have all five boss drops, you also need $25,000,000 Money and 22,500 Gems. Redeem active Sailor Piece codes to speed up both.
Go to Boss Island β find the Gilgamesh Trainer NPC (located above the floating stone hand sculpture). Interact with him, hand over all required items, and Gilgamesh is yours β no quests required.
The F ability β a sky-drop AOE fire blast β is locked by default. To unlock it (and gain a +30% Gilgamesh damage boost), craft a Babylon Key from the Babylon Key Crafter NPC on Boss Island:
| Item | How to Get |
|---|---|
| Servant Race | Reroll using Race Rerolls |
| 100x Broken Sword | Farm Slime Warriors |
| 5x Golden Essence | Gilgamesh Boss drop (1.5%β2.5%) |
| 2x Phantasm Core | Gilgamesh Boss drop (0.5%β0.75%) |
This is a serious grind. 100 Broken Swords alone takes significant time. Plan your farming around the Sailor Piece Ascension Guide to maximize money and gem rewards while you grind.

| Key | Ability |
|---|---|
| Z | Fires two consecutive beams of light |
| X | Surrounds enemies with golden circles, releases light beams |
| C | Cone-shaped slashing attack |
| V | Summons a swarm of golden circles that bombard enemies |
| F | Large AOE fire blast from the sky (requires Babylon Key) |
For maximum damage, invest all stat points into Melee, and pair Gilgamesh with the Havoc or Wrath Rune. Use the X and V moves to chain AoE damage during boss fights, and time your C move’s i-frames to dodge incoming boss attacks.
Expect 20β50+ kills to gather all required drops due to the low drop rates on Phantasm Core (0.5%) and Golden King Title (1%). Higher difficulty modes improve drop chances.
No, unlike Sukuna V1, Gilgamesh has no connected questlines. Once you have all required items, you can unlock the fighting style instantly.
On Boss Island, on top of the floating stone hand sculpture. Use the dock portal from any island to get there, then look for the hand structure to the right side of the island.
Yes. It’s an S-tier fighting style ranked among the best in the game, alongside Anos and Strongest in History. Its AoE damage and farming efficiency make it excellent for dungeons and boss grinding.
