Witch Doctor

=== Introduction to the Witch Doctor ===
The witch doctor is an alchemical master, skilled at not only simply brewing potions and alchemical goods, but at awakening the spirits of the ingredients that go into her goods. A witch doctor at work can be unsettling, for she croons and chants to the herbs and animal parts that go into her brew, shaking a rattle to awaken them from their slumber, and sometimes even bursting into dance to appease them and make them favor her. The powers that witch doctors revere are creatures of wild, ecstatic worship who demand dynamism from their servants. 
The witch doctor's arcane magical art is formed from the ability to twist and turn nature through a crude yet effective science called juju. Often the more cunning and savvy members of the savage troll tribes, witch doctors are uncommon among other, more civilized races that instead rely on shamanistic aid in times of need. During war, the witch doctor's juju can give a troll tribe a needed edge. Witch doctors teach that worthy trolls receive dominion over various aspects of nature upon their death - whether plants, weather, beasts, or even disease. When witch doctors exhibit their supernatural powers to cure the sick, control nature, or assist in battle, it is said that ancestral spirits are riding them.
The arts of the witch doctor originated with the trolls, and they make up the vast majority of those who practice these arts. Some of these witch doctors have agreed to take on the occasional non-troll apprentice, usually from among the orcs. (More Magic & Mayhem — A World of Warcraft RPG source book.)
Jungle Troll Witch Doctor
Trolls are the ultimate witch doctors. It was the trolls, so they say, who invented the art. Their pots ever bubble with strange concoctions, and they scatter protective and decorative totems around their dwellings. They speak in tongues most can't understand, communing with the strange voodoo spirits from their tribal religion that grant them their power. They decorate themselves with ritual tattoos and designs, and shrunken heads dangle from their staves. The iconic troll witch doctor focuses on helping his allies with his strange blend of science and faith. He plants magic totems to help his allies, which may start a bloodlust or an adrenaline rush in his body.A powerful witch doctor may even transform their foes into frogs. He's not a particularly skillful combatant, but when the Horde is in a scrape, somebody calls for the doctor. (Horde Player's Guide — A World of Warcraft RPG source book.)
Forsaken Witch Doctor
When people think of witch doctors, they usually don't think of Forsaken. However, Forsaken are some of the most skilled alchemists on Azeroth, and while they don't entreat voodoo spirits for help and don't call their craft "mojo," they still possess tricks to make their brews especially potent. These forsaken call themselves apothecaries. (Horde Player's Guide - A World of Warcraft RPG source book.)
=== World of Warcraft ===
In World of Warcraft, Witch Doctors are semi-playable as Troll shaman and warlocks.
A common title among troll mobs and NPCs, they range from the very powerful, Hakkari Witch Doctor, to the relatively weak, Bom'bay <Witch Doctor in Training>
There are also human witch doctors that are under the command of Colonel Kurzen in Stranglethorn Vale.

=== The Path of the Witch Doctor ===
Witch doctors can be described as a shaman alchemist.
The witch doctor's seething cauldron contains a hallucinogenic mixture of herbs, poisons, crushed insects and other noxious materials. He may add drops of this Shaka brew to improve the efficiency of any potion or alchemical item he creates. The Shaka brew maximizes all variable, numeric effects of the witch doctor's potions or alchemical creations. Drinking a potion treated with the Shaka brew leaves the imbiber with a euphoric buzz.
The Bambe brew is a secret recipe that extendes the effectiveness of magical potions. Drinking Bambe brew potions leaves the imbiber with a faint crawling sensation over their skin.
The witch doctor can add drops of the Zuvembi brew to any potion. The brew creates a powerful suggestive state in the imbiber that he can trigger and control. After drinking a Zuvembi brew potion, the imbiber can be dominated by the witch doctor.
Creating curses and hexes is a specialty of the witch doctor. The witch doctor can make a deadly doll of wax or tallow containing a specific person's hair, skin or blood. He can affect the target with a harmful touch attack spell as long as the person is on the same plane. The doll disintegrates after a touch attack.
The witch doctor chooses a simple wooden weapon ( e.g., staff, club, spear or javelin) that he prefers. He can infuse the weapon with alchemical reagents and various toxins and clays. He may imbue the weapon with the frost, flaming or thundering special weapon properties. This ability lasts depending on the skill of the witch doctor. Anyone other than the witch doctor who attempts to use the weapon while it is active suffers the ill effects of the weapon's special properties.
The witch doctor can shake and rattle the gourds and necklaces that he carries to create a frightening rhythmic effect. The juju of the highly skilled witch doctor becomes potent enough to kill (the Death Rattle). The arcane focus required to use this ability is a death gourd, which must be cursed and carved by the witch doctor himself using bizarre and disgusting components. The witch doctor can rattle his death gourd, targeting a number of living creatures, the closest creatures are affected first.
Much like a wizard, the witch doctor relies on his ability to bend magic to his will. Juju secrets can only go so far, though - Magic and Mayhem — A Warcraft RPG source book.
They also served as spellcasters for the Horde during the Third War, being able to create several types of wards for such activities as healing, trapping, and watching over land.
