Rengoku in Blox Fruits is a Legendary sword specially crafted to take down enemies of high caliber. With its sharp edges, you can pierce through the opponent's armor and reduce their HP to zero in just a few hits. In case a stronger enemy shows up, you can use Rengoku's flaming hot blasts to even things out.

Considering the potential of this weapon, you might want to unlock it right away. This guide sheds light on unlocking Rengoku in this title and explains how to upgrade the weapon as well.

How to unlock Rengoku in Blox Fruits

In this Roblox title, you can find Rengoku in the Ice Castle, Second Sea. This is an island located on the northern side of the Dark Arena. Upon reaching the Ice Castle, you will need an item called the Hidden Key. Remember, you won't be able to obtain the Rengoku sword if you don't possess the Hidden Key.

To get the Hidden Key, you must defeat the enemies that spawn outside the Ice Castle. Arctic Warrior and Snow Lurker are the two enemies that spawn in this area. As the chances of obtaining the Hidden Key are low, you will have to try multiple times before you finally get it.

Once you get the Hidden Key, head inside the castle on the peak of this island. From there, go to the area with a staircase in front. If you notice carefully, there's a secret wall on the right side of the staircase. You can get past this wall by just walking through it. Behind the wall, you will find a treasure chest containing the Rengoku sword. The treasure chest can be unlocked by using the Hidden Key that you obtained earlier.
