The Rengoku is one of the many Legendary swords found in Blox Fruits. Hosting high damage stats, unique slash techniques, as well as the ability to target multiple players at once, it's no surprise that users often opt for this weapon when facing off against enemies. If you're looking to add this powerful item to your collection, simply follow the steps found below!

To get the Rengoku, you'll first need to obtain a Hidden Key. This can done from taking out an Awakened Ice Admiral (who has a 5% chance of dropping the key after death), or from defeating an Arctic Warrior or Snow Lurker which have a lower chance of dropping the key after death.

The Awakened Ice Admiral can be found at the top of the staircase inside the Ice Castle in the Second Sea:

The Arctic Warrior and Snow Lurkers can be found outside the Ice Castle in the Second Sea:

Once you've obtained a Hidden Key from taking out these enemies, you'll need to then head to the Ice Castle, found on the same island. Next, head inside and go to the right of the staircase below where the Ice Admiral is found:
