Step-by-Step
How to Get the Dark Blade V2 in Blox Fruits

- Buy from the Blox Fruit store for 1,200 Robux—it’s the fastest method.
- Receive it as a gift or trade from a player who owns the Game Pass.
- Find the Brazil Cube—cross paths with developer rip_indra to get it and claim the blade.
- Defeat the Mihawk boss—a tough challenge, but there's a slim chance you’ll earn the blade as loot.

- If you don’t meet the criteria, Robotmega will say, “idk of u.”

- Say me why

- Frozen Village: Left of a ladder, break an invisible wall using your Dark Blade’s Z-move to reveal the letter.
- Skylands: In the center of the island, find a blue two-story house with a gray tin roof. Smash the door with your blade to get the letter.
- Marine Fortress: Behind the Vice Admiral’s mansion is an invisible wall. Break it, then follow this maze path: right, left, left, right, left, left—to find the last letter.
