During his mortal life as the Warchief of the Orcish Horde of Draenor; Ner'zhul commanded a number of Orcish Warlocks and Shamans. 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. These Liches possessed tremendous magical powers, yet their immortal, undead bodies were bound to the iron will of Ner'zhul. Since the Liches showed unswerving loyalty to their master, Ner'zhul granted them control over the furious elements of the cold north. Now, Liches wield frost magic along with their own considerable necromantic spells.
The Lich is the least used Undead Hero, partly because it is difficult for beginners to use him properly. The Lich is a great first or second Hero mainly for his Frost Nova ability. Frost Nova is one of the uber abilities in the game, especially when combined with the Archmage's Brilliance Aura, Mana Potions, or Dark Ritual. Frost Armor can be useful on allied Heroes, Abominations, or Frost Wyrms. Dark Ritual is rarely used but is very powerful in a skilled player's hands. Dark Ritual works very well with Necromancers because the Lich can sacrifice Skeleton Warriors. Death and Decay can be used to attack tightly packed enemy buildings or towers.
The Lich is a very fragile caster like the Human Archmage. He can easily and quickly be killed. You can attempt to counter that by casting Frost Armor on him or healing him with Death Coil. 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.
Spells and Abilities
- People pick the Lich just for the Frost Nova ability. It is a very powerful ability that is up there with Chain Lightning. Frost Nova can take a chunk out of enemy units and destroy low hit point units such as ranged units and spell casters. The second benefit of Frost Nova is that it slows enemy units so it's great to use when they are trying to run away.
- Use Dark Ritual so you can get more Mana to cast Frost Nova.
- Frost Armor is useful for protecting allied Heroes and the Lich Itself. You can also cast Frost Armor on powerful units such as Abominations, Frost Wyrms, Knights, Tauren, and Bears to allow them to last longer. The slow ability is also useful because enemy units attacking a unit with Frost Armor will be slowed for 5 seconds.
- Frost Armor only slows units that attack the unit with a Melee attack.
- Death and Decay is useful for attacking enemy towns when they have packed their buildings very tightly. You can then destroy a lot of buildings and greatly damage the enemy. Death and Decay is also useful against people who build a lot of towers.
- Death and Decay can be used to clear away trees, as they are instantly destroyed by Death and Decay.
