How to Unlock Accessory Fusing in One Piece Odyssey

Accessory fusing is a process by which you can combine two or more items to create a more powerful item with enhanced stats. When you use the accessory fusing system, you will be able to combine two or more items to create a more powerful item with enhanced stats. You can also fuse items together to increase the stats of a single item, or combine them to create a completely new item with boosted stats. 

To access the accessory fusion system in One Piece Odyssey, you will need to make your way to chapter 3. When you arrive at Waford from Alabasta, a cutscene with Lin will appear. She will discuss a robot in the camp that needs to be investigated. Robin will then use her arms to operate the robot, which will unlock the fusion mechanism. 

Once the robot is unlocked, you will be able to access the fusion system. You can choose which two or more items to fuse together, and the game will show you the potential outcomes of the combination. There are three potential outcomes: Complete, Success, and Triumph. In the Complete outcome, the original value of the item is transferred to the host item. In the Success outcome, 150% of the fused item's value is moved to the host item. Finally, in the Triumph outcome, 200% of the fused item's value is transferred to the host item.
