From page 24 of the PDF: Combat Rolling Rules To make an attack, you must roll the associated weapon skill using 2d10. Pick two different d10 (Preferably visibly differentiable) and decide which is the 10s place and which is the 1s place. Now roll them. If the 10s place is a 0 (Or a 10, based on the label of the dice), then that means the roll is between 1 and 9. You only get a 100 if both dice show 0s (Or 10s). Don’t feel bad, though. 100 is a critical failure. When you roll your stat, you are trying to get a result AT OR BELOW your current skill level. For almost every case, rolling closer to 0 is better. And if you roll between 1% and your luck stat, you’ll score a critical. [puts on ModHat] At this point, we've gone beyond the scope of this forum.
