Dual Dark Blade is a Sea 3 mythical sword in Haze Seas. You craft it at Doran the Forge on Land of the Gods (Sea 3 Starter Island). The live recipe is 20 Ancient Blade Relics, 300 Mastery on Dark Blade V2, 5 Abyssal Eyes, and 20M$.
Older pages still list 1 Abyssal Eye and 25M Bounty. That set is outdated. Skip it and farm the four live gates instead.
The hard part is not one boss. It is stacking relics, finishing Dark Blade V2 mastery, and killing Cthulhu five times for eyes.

These are the only craft gates. Bounty is not required.
Dual Dark Blade requirements
Dark Blade V2 and 300 Mastery
Doran will not finish Dual Dark Blade until Dark Blade V2 sits at 300 Mastery.
- Own Dark Blade (V1). Buy it from the Robux shop, or craft Free Dark Blade at Doran if that path is open (often listed as 20 Ancient Blade Relics, 1 Abyssal Eye, and 1000 Gems). Free Dark Blade is a separate craft from Dual, so do not burn Dual materials by accident.
- Talk to Nikk0Lapz at Foggy Castle and hand over a Legendary or Mythical fruit.
- Defeat Enma.
- Pay 50 Gems to spawn the Dark Blade Boss (about every 2 hours).
- Beat the Dark Blade Boss for Dark Blade V2.
- Grind the sword to 300 Mastery.
If you already own the gamepass Dark Blade, start at Nikk0Lapz and skip the free-craft detour.
Ancient Blade Relics
You need 20 relics. Two paths cover most of the grind:
- Craft at Doran the Forge. Each relic costs 5 Blade Fragments, so full crafting can eat 100 fragments. Fragments drop from Sea 3 Super Bosses at a low rate (about 10%).
- Buy from the Wandering Merchant in Sea 3. Relics cost about 1M$ and fragments about 300k$. The merchant spawns about every 1.5 to 2.5 hours, stays roughly 7 minutes, and can leave after big buys, so treat the chat ping like a race.
Abyssal Eyes from Cthulhu
Cthulhu drops 1 Abyssal Eye every kill (100%). Dual Dark Blade needs five eyes, so plan on five summons.
Cthulhu is Level 10,000, has two health bars, and does not use a short despawn timer. It roams until dead, which gives your team room to regroup between forms.
Craft a Prismatic Shard at Doran first. The five materials are:
- Phantom Lantern from the Ghost Ship event
- Dragon Heart from the Dragon boss
- Sea Beast Heart from Sea Beasts in Sea 2 and Sea 3 (often about 25%)
- Raijin's Core from the Raijin boss
- Saturn's Ring from the Saturn boss
Summon during Storm:
- Wait for Storm weather (about every 2 hours 35 minutes, with a ~10 minute window).
- Find the whirlpool under the rainbow sky islands in Sea 3.
- Interact while holding the Prismatic Shard. The shard is consumed and Cthulhu spawns.
High-mobility fruits help on this fight. Team up if you can, and try for top damage if you also want the Legendary or Mythic fruit roll on the same kill.
If you still need free Race Spins after the update, check active Haze Piece codes before they rotate out.
20M cash
Bank 20M$ before you open Doran's Dual craft. Normal Sea 3 loops, Sea Beasts, and timed events cover it. No extra currency type is required beyond cash.
Craft Dual Dark Blade at Doran the Forge
When every gate is ready:
- Travel to Sea 3 Starter Island (Land of the Gods).
- Enter the castle area and talk to Doran the Forge.
- Select Dual Dark Blade in the craft list.
- Confirm the craft with all materials and 20M$ ready.
Dual Dark Blade is the dual-wield end of this sword line. Free Dark Blade and Dark Blade V2 sit earlier and use different recipes. Finishing Dual also unlocks the Bearer of the Eternal Night title.
Moves once equipped: Midnight Havoc (0), Trillion Slashes (25), and Soul Eruption (50).
Players who already chase fruit-and-sword mastery in games like Blox Fruits will recognize the mastery gate, even though Haze Seas keeps its own Sea 3 materials and Cthulhu loop.
