To do raids in Blox Fruits, you must first reach level 1100. This is the minimum requirement to unlock raids in the Second Sea. Once you have achieved this level, you are ready to start your journey.
Next, you need to obtain a Special Microchip. You can buy this chip from the Mysterious Scientist NPC for $100,000 or trade any physical Devil Fruit for it. This chip is essential for entering the raid.
Head to the Hot and Cold island in the Second Sea to find the raid area. Enter the code “red blue green blue” on the console. Then, proceed through the space in the wall to the left of the console by the pipes.
Once in the raid area, press the action button while standing there in your untransformed form. This will teleport you into the raid. Be ready for a tough battle as you fight through five islands with increasing difficulty.
Complete the raid by defeating the boss within 13 minutes. You’ll earn fragments and can awaken your fruit. Be cautious, as dying during the raid means you won’t receive any rewards.
