Skill Checks

Skill and Difficulty

A skill check is called for when a character is taking a risk, hoping for a favorable result, and betting that the circumstances and their individual skill are enough to achieve success. The percentage chance of success may be modified by many circumstances. This modifier is usually expressed as the Difficulty Class of the check.

ModifierDifficulty Class
add 40% to chanceEasy
add 20% to chanceModerate
no adjustment 0%Hard
subtract 20% from chanceHeroic

It’s important for the player to be able to make rough judgements about difficulty class as part of their decision whether or not to have their character attempt a certain action. Some examples of actions, their related skills, and approximate difficulty class, are listed below:
