A Less Cumbersome Blackmail System

Get a scandal: http://detectmagic.blogspot.com/2014/02/scandal.html.

When the blackmailers actually deliver the threat to reveal the scandal, think, and take the highest:

Would the revelation destroy:

• treasure (+1)
• reputation (+2)
• life (+3)

Subtract 2 for each of the below that is true:

• target of blackmail is not subject of scandal
• they have and cannot be expected to acquire proof of subject's involvement in scandal 

The blackmailers name their price. How rich (in the eyes of the target) is it?

• pocket change; an annoyance (-0)
• serious clink, but recoverable or concealable with little effort (-1)
• a big chunk, requiring significant effort to recoup or conceal (-2)
• a fantastic sum, impossible to hide or ignore (-3)

Now secretly roll 2d6 + [bonus] (and HT: Vincent Baker for this sort of setup):

• 10+: target complies, will not retaliate unless given perfect opportunity
• 7+: Show no respect to blackmailers, display obvious contempt: this puts the blackmailers in position to take action against the target; the next reasonable action they propose against the target will succeed, no roll. 
• 6- (GM chooses one):
• target retaliates now (played politely or contemptuously)
• target retaliates later (played politely or contemptuously)
