Quick note on something Mr Sark said about how it is surprising how often people have gotten screwed by the botch table. Sark says that the odds are very low to end up on the very bad end of the botch table but if he is using two ten sided die to do percentile than the likelihood of getting 90% or higher is actually 10% of the time. You know, getting a 9 on the die that represents the tens place is 1/10. It's actually harder to botch (1 out of 20 for 5%) than it is to be on the epic end of said botch. So it is more likely for your botch to be bad than it is to botch in the first place. I think there is more complicated math in here with adding in the chances of rolling two zeros (quick search of internets finds nothing on percentile dice odds) but you get the idea.
