each of your characters skills will have a score out of 100. for example my Repair skill is 32, when making a Dc Check outside of combat you will use a d100 (the D10 and Percentile D10 dice) to determine if you succeed or fail the task. to do this first you must role your D100 (Roll both the standard D10 and the percentile D10) and then add your skill score to the Roll. as in the example Below 

 

for this example we will pretend my character is rolling to find a fault in a broken water purifier the Dc is 75 and my Repair skill is 32

First I rolled  40 on my percentile and 8 on my standard 10 so my roll for this check is 48

Next I Add my Repair skill of 32 for a Total of 80 

As the Dc was 75 my character has successfully found the fault and passed the Dc Check 

 

 

Examples of DC (Difficulty Class) Scores 

Dc 25 - Easy

Dc 75 - Medium 

Dc 150 - Hard 

Dc 200 - Very Hard 

Dc 250+ Virtually Impossible

 

Understanding Your Dice 

The percentile Die 

This dice is a variant of a Standard D10, it has 10 sides reading 00 - 90 and controls the Tens digit for your D100 

The D10 

This dice is a standard D10 and its Faces will control the single Digit for your D100 

Understanding Your Roll 

Below are three examples of D100 Rolls that people frequently get wrong and what they mean. 

00 0 = 100

10 0 = 10 

00 1 = 1
