a new skill is defined as Craft (Juryrig).
Thinking about it, how about making the action of juryriging a challange of Disable Device?
I figure that if you are able to disarm or sabotage a device then you would have some knowledge of how it works, so it makes sense that you could use the skill in reverse and as a challange.
(for Disable Device)
You attempt to make a device that is broken work for a short period of time. The length of time that the device works for should be determined by the Narrator and based on by how much the challange was made by.
You attempt to reverse someone else's use of Disable Device on an object. This could be a contest of Disable Device skills.
Both of these challanges are at -10 unless the character has access to appropriate "spares" of some kind, which drops the penality to -5.
What do you think?
