If to hit modifiers result in a required score of 7 or more when shooting than it is still possible to score a hit, though very unlikely. As it is impossible to roll a 7 on a D6, you will first need to roll a 6 and then, for each shot scoring a 6, you will need to roll a further score as shown on the chart below. So, for example, in order to score an 8, you must roll a 6 followed by a 5 or more. If you require a score of 10 or more than it is impossible to hit the intended target.
