This design is too safe! Too restrained! It can be improved.
The Technician uses their tools to attach a Thorium Core to an object. The core supercharges the item, increasing its quality dramatically. However, once the core runs dry, the object is rendered less useful than it was before. The core crackles with blue electricity while active.
Exert your Mind and work on the object in question for One Minute using a standard set of tools. It receives 3 extra dice to all actions taken with the intended application. This effect lasts for One Day, after which, the object is at a -2 dice penalty until repaired by an expert or Upgraded again.
As always, dice bonuses to the same dice pool do not stack. Instead, the higher bonus is used.
