Though they retained their Humanity after making a pact with death, Necromancers became the most terrifying agents of the Scourge. These dark, insidious men were once thought to be aspiring geniuses by the Magocracy of Dalaran. However, their insatiable lust to delve into the secrets of the dark arts drove them to forsake their very souls. Ner'zhul, the Lich King, granted these malevolent sorcerers true power over the dead in exchange for their loyalty and obedience. The shadowy Necromancers have the power to command various types of Undead and even spread the foul undead plague as well.
Essential spellcaster. Can initially cast Raise Dead on corpses. Can slo learn Unholy Frenzy and Cripple. Attack land and air units.
Spells & Abilities
Once the Skeletal Mastery upgrade is researched, Raise Dead will raise 1 Skeleton Warrior and 1 Skeletal Mage per corpse. This spell is not on by default. This is to prevent the Necromancer from raising Skeletons from the Graveyard after he is created wasting his mana if you happen to build your Graveyard next to the Temple of the Damned.
Skeletons initially last 40 seconds. Research Skeletal Longevity to increase their time 15 seconds to a total of 55 seconds.
The attack rate of heroes only gets increased by 50 % (instead of 75 %).
Unholy Frenzy is very helpful on Heroes (whose health regeneration can make up for the loss of hit points), Abominations, Frost Wyrms, Tauren, Knights, and Bears. For some units, such as low hit point units, it is not a good idea to cast Unholy Frenzy on them because it will make them so weak they will be easily killed.
Unholy Frenzy works very well in combination with the Dread Lord's Vampiric Aura on Abominations and other advanced melee units and on melee heroes such as the Dread Lord. The Vampiric Aura will help heal the damage of the Unholy Frenzy.
Cast Unholy Frenzy on retreating enemy Heroes, or even units that are about to die. It will kill them off.
Cripple is the uber slow spell. It also requires a lot of Mana. You should pick your targets carefully when casting Cripple. Cast it on powerful normal units such as Knights, Tauren, Abominations, Frost Wyrms, or Druids of the Claw.
