Ability check probabilities

When rolling an ability check, there are two ways you can roll. You can either roll against a target difficulty, or you can roll against another character in an opposed roll. For both rolls, you roll the dice and count the number of 5's and 6's


Against a difficulty

This table shows the percentage chance to hit a target difficulty
