# Difficulty Class (DC) For every check, the GM decides which of the six abilities is relevant to the task at hand and sets the Challenge Value as Difficulty Class (DC) for the task. The more difficult a task, the higher its DC. The table below shows common DCs. | **Task Difficulty** | **DC** | | ------------------- | ------ | | Very easy | 5 | | Easy | 10 | | Medium | 15 | | Hard | 20 | | Very hard | 25 | | Nearly impossible | 30 |
