Well it's always good to try and understand how this system works ha
One question, But by having extra rolls on the dice surely your more likely to roll a 10 if the 10 is the crux?
The more rolls the higher the chance
The percentage will always be 10 (assuming 10 is the correct number.) it doesn't matter how many chances there are, the number always stay the same. It still stands that every roll, 90% of the time, you will be getting something other than the crux. If you have 100 rolls, it's still only a 10% chance during all 100 rolls that it will be the crux. Obviously, more rolls equals more chances. But the chances are still the same percentage. You can rationalize that out of 100 rolls, you should end up with 10, but it's not true.
