No matter his race or allegiance, the quickest and easiest route for a warrior to earn glory and a dread reputation is by killing enemy heroes in close combat. I don't mean through a chance blow in the brutal crush of melee – after all, even the most cowardly peasant can poke a spear through an enemy warlord's back, should he get the opportunity. No, what I'm referring to is a duel between mighty warriors, the clash of sword upon and sword and axe upon shield as two doughty fighters strive against one another in a contest of battle-skill. In Warhammer, we refer to such battles as challenges.
Challenges are one of the most dramatic parts of Warhammer, representing as they do the final showdown between opposing warlords or hated rivals. It's not unusual for the result of a battle to hinge on who wins a challenge!
