Precision Hexing

[whitelaughter]

Simply trashing a technological item is straightforward, but how would you go about more detailed interference?
Possible examples:
causing a mechanical watch to run slow or a mobile phone to burst into flames.
While making a car cease functioning is straightfoward, how about ensuring that the brakes fail?

A character who only has Mana  Static is going to want to play with the implications of his power, while a more powerful character could create spells to focus or refine what can be done.

Suggestion?

According to the hexing rules on page 259 of Your Story, this sort of thing is mostly not allowed.

Hexing cannot be used to manipulate technology - only destroy it. You cannot use hexing to do maneuvers unless destroying the device is precisely what justifies the maneuver. So if there's an advanced filtration system in a building keeping gas out of a room, you could hex the control panel to put the Aspect FILLED WITH GAS on the room, but you couldn't selectively control the gas flow in any way.

Despite that, I would be inclined to be flexible with hexing maneuvers. Seems like it'd lead to more interesting gameplay.
