In Dungeons & Dragons-based games, many checks are made against a task’s Difficulty Class, or DC during the course of gameplay. The DC is a target for character skill checks. These are set by the video game's developer, or in some cases by a module designer. For example, a certain type of trap kit may have a DC of 15. To set the trap, the character must get a result of 15 or better on a Set Traps skill check. Note that certain circumstances may modify a character’s skill modifier (armor penalties and the like), while others may modify the DC of the task (the trap may be faulty).
