Robotrek Inventor’s Friends

Robotrek has a unique system for equipment progression. Rather than buying new equipment in shops, our hero creates new equipment either by combining scraps and equipment that he finds in capsules, or by reading about new equipment in a magazine series called “Inventor’s Friend”. Inventor’s Friends are scattered all throughout the world (and in outer space), and the hero can comprehend any Inventor’s Friend volume equal or lower than his experience level. After reading and understanding one of these volumes, you can spend money at any Inventor’s Machine to create that piece of equipment.

Below is a list of all of the Inventor’s Friend volumes in the game, their location(s), and how much it costs to create the item. Worth noting is that every volume can also be found in Kirara, the hidden library in outer space (though volumes 60, 70, and 80 only exist there). While not found in Inventor’s Friends, I also listed the 4 other flash items that can be learned and created.
