Rengoku Sword location in Blox Fruits
You can find the Rengoku sword at the Ice Castle in the second sea. However, you can’t just pick it up and start using it. The blade is locked inside a chest. You need to get the Hidden Key for the chest, and once you have that, you can unlock it. You can find this chest behind the wall on the right side of the stairs inside the main castle. This is also where you fight the ice admiral.
How to get the Hidden Key at the Ice Castle
If you don’t have the Hidden Key, there are two ways to get it. The best method is killing the Awkaned Ice Admiral inside the castle. He has up to a 15% chance of dropping the key when you kill him. However, killing the admiral is difficult, especially if you are lower level. This is where the second method comes in: killing the NPCs on the island.
The NPCs that drop the key are Snow Lurkers and Arctic Warriors, and you can find them outside the castle in the main island area. They have up to a 1% chance of dropping the Hidden Key, which is extremely low, but killing 15 to 30 of them should give you the same 15% chance as the admiral. Still, you will have better luck with the admiral. If your level is low or luck is not working with the admiral, the NPCs are an excellent way to grind for the key.
