Gadgeteers use devices to power themselves. Depending on origin, the items can be technological or mystical in nature.
Each power takes the form of a gadget, and losing that gadget means you lose the use of that power. The same is true of exceptional attributes; any attribute over 10 requires a gadget, and if you lose the gadget, the part of the attribute in excess of 10 is halved (rounding up).
Lost gadgets can be replaced in between sessions or with some work during sessions.
This limitation applies to your first five Super schticks and/or exceptional attributes. If you have more than that, you can take it again to have it apply to all of them.
