However, once the Paladin ranks were disbanded by the failing Alliance, many of these holy warriors traveled to the quarantined lands to ease the suffering of those left within the plague-ridden colonies. The second and third point in Frost Armor do not give nearly as much of a damage reduction boost as the first point.Death Knights were once proud Paladins and virtuous defenders of Humanity. Even at spell level 1, Frost Armor reduces damage output of melee attackers by over 50% due to the armor increase and attack speed slow.

Putting one point in Frost Armor gives extraordinary bang for the buck.Use Frost Armor to slow down the movement speed of melee units trying to finish off your retreating warriors. Frost Armor only slows units that strike with a melee attack.Good players manually cast Frost Armor on units that are under attack from melee enemies in order to get the most value for the mana spent. Frost Armor can be auto-cast, but savvy enemies can exploit this behavior to quickly drain the Lich of its mana by forcing Frost Armor on low quality targets.Frost Armor is useful for protecting allied Heroes and the Lich itself, who is frail without Frost Armor active.The most common way to protect him is to do a lot of running away and never get close to enemy ranged or melee units whenever possible.

Since the Liches showed unswerving loyalty to their master, Ner'zhul granted them control over the furious elements of the cold north. These Liches possessed tremendous magical powers, yet their immortal, undead bodies were bound to the iron will of Ner'zhul. Yet, when these wicked sorcerers were captured by Kil'jaeden and the Legion after the destruction of Draenor, they were transformed into twisted aberrations of their former selves. During his mortal life as the Warchief of the Orcish Horde of Draenor Ner'zhul commanded a number of Orcish Warlocks and Shamans.
