The frozen north spawns some of the hardiest warriors in all the world. Each is a paragon of deadly ability and lethal intent. Some ascend to command entire nations, some pursue the esoteric paths of the arcane, but the majority dedicate themselves to little more than the brutal butchery of all who stand in their way. These ruthless killers are known as Exalted Heroes. The history of many Exalted Heroes, recorded in scattered chronicles by the free people of the Old World, is a catalogue of woes and evil deeds. Their infamy shines bright as they capture the notice of the Dark Gods of Chaos with ever-greater feats of slaughter. They frequently seek out others of their kind to engage in ritual combat. When two Champions of Chaos clash, they duel to the death in the manner of gladiators, using the full force of every weapon at their disposal. When a victor emerges, bloodied but triumphant, he will cut a grisly trophy from his foe, claiming both his vanquished enemy's weapons and followers as his own. If the triumphant Champion has truly excelled, he may even succeed in attracting the attention of the Dark Gods and, in doing so, receive a more permanent reward for his deeds in the form of a mutation of daemonic gift. With each victory, the Champion grows ever closer to becoming a Chaos Lord, with whole armies to command and daemonhood within his reach.
↑Armoured & Shielded: Armoured units can block damage from any source apart from Armour-Piercing damage. Shields have a chance of blocking arrows, bolts, rifle shots and similar small arms fire - but only in a forward facing arc.
↑Vanguard Deployment: This unit can deploy in an expanded deployment area, allowing it to start the battle within striking distance of the enemy - or somewhere unexpected.
A niche unit on the Chaos roster, they are useful for providing a bit of added support and backbone to a Chaos frontline. Perhaps best if you are using Marauders or Chaos Warriors who are not the strongest units in the game. They have strong melee stats and have magic damage, but err on the defensive side with little armour piercing damage. Their encourage aura will help keep allies in the fight, especially if your lord is focused on a cavalry or monster fight (Archaon or Kholek). They have Vanguard Deployment, so can be used at some cheeky off angles, but they will most likely get picked off and isolated unless they are supported by another unit. If one wanted to use them in a rush build, I suppose their vanguard would help then, but that is a bold strategy.
