During a battle, a model might have to take a test on one of its characteristics. In order to pass the test, the model has to roll a D6 and score equal to or lower than the value of the characteristic involved. Note that if a 6 is rolled, then the model will automatically fail the test regardless of the characteristic's value and of any other modifier that might apply. If a model has to take a test for a characteristic that has a value of 0 on its profile, it will automatically fail the test.
