Trait Rolls

To make a skill or attribute “check” or “roll,” simply roll the die assigned to it. If the result is a 4 or better (the “Target Number” or TN), the action is successful.
For example, if a character’s Strength is a d6, he rolls a six sided die. On a 4 or better, he’s successful.

Modifiers

Circumstances modify the die roll, such as shooting at something far away or finding a well-hidden clue. Some things, such as ranged attacks, have standard modifiers. It’s up to the GM to determine any modifiers for more subjective tasks, such as spotting an ambush or eavesdropping on a conversation through a door.

• In general, an easy task, such as finding tracks in the mud, is made at +2.
• A difficult task, such as finding tracks by torchlight, is made at −2.
• A very difficult task, such as finding tracks in a rainstorm, is made at −4.

Multiple Dice

When a character rolls multiple dice, such as when firing a machine gun, check each die separately.
