What is a World of Warcraft warlock?

Answer 1

A warlock is a playable class in World of Warcraft. It's primary function is a ranged damage dealer or dps(Damage Per Second). The warlock uses dark magic, has a pet and is ranged. Dots(Damage over Time, a spell that continues to damage the opponent over a period of time that does not require the caster to continuously cast the spell) are important which will kill your enemy over time. These are very powerful as you level up.

[Edit]: Warlocks are masters of the dark arts, devoted to furthering their understanding and use of Shadow and Fire based magics, along with the summoning of demons from within the Twisting Nether. They first appeared on Azeroth during the First War, when Gul'dan, the first of their kind among the invading orc clans of Draenor, led the Horde across the dimensional gulf through the Dark Portal while in servitude to the Burning Legion. Warlocks are used as damage dealers, but can store the target´s soul to resurrect or heal himself and others by draining enemy's life. The warlock can summon an imp without a Soul Shard. However, other demons, such as voidwalkers, require a soul shard or other reagents to be summoned.
