When things are uncertain and you need to resolve a situation, it is common to make checks, by rolling a d20 against the Difficulty Value (DV), adding modifiers and comparing the two.

There are four degrees of success when rolling a check:

Result Description
Critical Success You rolled +10 higher than the DV. 
You succeed and more!
Success You rolled equal to or higher than the DV. 
You accomplished what you set out to do.
Failure You rolled less than the DV.
You did not accomplish what you wanted, or success comes at a cost.
Critical Failure You rolled -10 or lower than the DV.
Not only do you fail, you experience a setback.
Additionally,

When specific outcomes are listed for all four degrees of success, use only one outcome unless otherwise specified. If outcomes are only given for success or failure, they apply for critical successes and failures too.
