The Necromancer is a dark spell-caster whose incantations are geared toward the raising of the dead and the summoning and control of various creatures for his purposes. Although his goals are often aligned with those of the forces of light, some believe that these ends cannot justify his foul means. Long hours of study in dank mausoleums have made his skin pale and corpselike, while his figure has more in common with a skeleton than a man. Some shun him for his peculiar looks and ways, but none doubts the power of the Necromancer, which is the stuff of nightmares.
There are three skill sets that the Necromancer can develop as he moves forward in the Diablo II Universe. As with the other characters, the skills you choose to develop substantially affect the Necromancer's abilities throughout the game. The three skill sets are Curses, Poison & Bone, and Summoning & Control. There are good reason to invest at least some skill points in each of the skill areas, but ultimately you'll have to make a decision as to which kinds of abilities you want your Necromancer to have.
The Necromancer, as his name would imply, has the ability to raise the dead and employ them to do his bidding. The Necromancer's power extends not only over the dead, but also over the elements, which means that he is also capable of summoning Golems from the ground beneath his feet, calling up the fires of Hell, or even creating a Golem that steals Life for your cause.

The Curses are a set of skills that affect the enemy hoards in various ways. As a rule, Curses are used in conjunction with other attacks, such as skeletons or golems. In multiplayer games, Curses work to the benefit of the entire party, not just the Necromancer using them. For example, an Amplify Damage curse invoked on a group of tough monsters will literally make it twice as easy for your group to take out those enemies.
