Exalted 3rd Edition
Ranges are given in Standard Deviations. Roughly 68% of all rolls will fall within the range shown. (Because the distribution of dice rolls is not Gaussian, this is just an approximate range - it should be tighter on the low end and stretch out a little on the high end.)
10s are doubled on every trick except for "Don't double 10s." For example, "Exploding 10s" is actually "Exploding 10s with double 10s. This is why "1s subtract" has the same average as "Don't double 10s" - because it's actually "1s subtract and double 10s," and those effects cancel out when it comes to the average.
