Gadgets are the Inventor's main ability. These gadgets are tools that can be used without the need for dice to cause various effects on the player or the enemy.

After each combat in most episodes, the player is given a choice of one piece of equipment from at most three choices to be scrapped into a new gadget, while the old gadget is discarded. However, in Episode 5, the player has to choose between one piece of equipment and another piece of equipment that was equipped for the fight at random to be turned into a gadget.

In Episode 3, gadgets are not discarded after a fight, but each equipment that breaks creates a new gadget that can be used as soon as it is created.
