Not all hits will wound their target - some might merely graze it. Some creatures are so tough that arrows do not easily pierce their flesh, or are so resilient that they are able to ignore missiles sticking out of their body. Once you have hit your target, roll again to see if it has been wounded. To do this compare the weapon's Strength with the target's Toughness. The Strength values of common missile weapons are given later; the target's Toughness is included in its profile.
Roll a D6 for each hit scored and consult the To Wound chart below. Find the weapon's Strength and look down that column. Then scan along the row for the target's Toughness. The number is the minimum score on a D6 needed to score a wound. Where the value is 'N' this indicates that the target is too tough for you to hurt. 'N' stands for no effect - or no chance!
