Fragments are necessary and indispensable if you plan to dedicate yourself to building robots. There are 3 different types of fragments:
  • frame
  • Tool
  • Core
As you can guess, the frame is the body of the robot but it is useless without its respective work tool and the core that will provide it with energy.
Each fragment comes in 4 rarities, and you will need 3 shards of the same rarity to craft a robot. So if you get a piece that you don't need, you can trade it with another player.
