A nuker is a character (or creature) that uses ranged damage spells as offense, rather than being a Tank or Healer. Their higher damage ability is usually balanced with low defense; the Mage is the prototypical nuker, though Warlocks and Hunters can also serve as nukers. The term is somewhat misleading in the context of World of Warcraft, as several other classes can perform this role without necessarily being archetypal casters; the preferred and more neutral term is simply damage per second or (playfully) pewpewer.
