The Long Arm of Murphy's Law
Entropy 1
Collecting a detailed set of information on his target -- be it institution, individual, or social phenomenon -- the mage converts a selection of key pieces of data and extracts their numerological values. These numbers are then employed as a 'key' to attack the whole body of information. Employing the key, the Mage extracts a short statement from the bulk of data, indicating what action he may take to bring Murphy's law to bear on his target. This effect is entirely passive, and only reveals to the mage what indirect actions he may take to set off a chain of events detrimental to his target.
System: Intelligence+mathematics, difficulty six. Successes subtract from the following roll: perception+enigmas, difficulty 10, -1 for each success on the intelligence+mathematics roll. The number of perception+enigmas successes determines how effective and expedient a course of action the Mage may take.

Mechanics: Storyteller whim

Example:
Hiro takes a press release from Hyperion and cross-references it to page 67 from their employee handbook to generate an encryption key which he uses on a copy of Ryo's last speech. This reveals that he must 'touch the flab hospital with granny home fubaz', meaning he must steal a bag of cellulite from behind the Toronto City Hospital and leave it on the front doorstep of a ms. F. U. Bazinki, where wild dogs will tear it apart, feasting on the fat. Ms. Bazinki will attempt to drive the dogs off, and will succeed with only a minor injury - a superficial bite on her leg. Nonetheless, the dogs had rabies, and she ends up in the hospital 4 days later where she bites a volunteer who takes classes at Ryo's dojo. Ryo contracts rabies.
