Toolboxes boost a certain parameter of your spare part by a certain number of points. There are currently four types of toolboxes:
  • Attack Toolbox - increases your damage per second. Can be applied to any weapon
  • Health Toolbox - the toolbox that increases your health. Can be applied to a chassis, gadget, or wheel
  • Power Toolbox - increases your power. Can be applied to a chassis
  • Magic Toolbox - fuse it with any part to boost its magic bonus
You can obtain a toolbox by opening Supply Boxes.
Note that the more toolboxes you fuse into a part, the more expensive the fusion will be. Also, the toolboxes will disappear when you enter Prestige.
