When you are attacking in Illuminati and you're in the phase where players are spending Megabucks to aid or hinder the attack, is there a limit to how money can be spent to reduce the power of the attack?
Let's say that, after all the modifiers for alignment, the power of my attack is 8. Can another player reduce the power to -2 by spending 10 Megabucks? If so, do I actually get to roll the dice, or does the attack not take place at all? Or are they limited to spending 6, which gives me at least a miniscule chance to succeed on the attack?
