Points values are based on these values, but are often modified slightly to take into account special abilities or vulnerabilities. You will find the full points values for each army in its own army list in the appropriate Warhammer Armies book. You will also find some examples on the sample file cards provided with Warhammer.
By way of example, consider the Bretonnian Bowman. He is an ordinary man (5) points and in addition to his sword he carries a longbow (+3 points). His points value is therefore 8.
The Saurus Warrior is far more expensive as befits his huge muscular frame and relentless attack. His basic value is 14 and in addition to his club or mace he carries a shield (+1). His points value is therefore 15.
The remaining models in the Warhammer box are both exceptions to the basic system. In the case of the Knights their points have been slightly modified to take into account their special Knightly abilities. Skinks are also an exception. Because their points value is so cheap they are allowed to buy extra equipment at half cost, paying 1/2 point for their short bow rather than 1. Creatures with a basic value of less than 5, such as Goblins and Skaven, are able to buy extra equipment at half cost to reflect their poor fighting qualities.
