Jesseth Arms (2 items, minor weapons set): a supplementary pet-oriented set, Sacrifice-themed.

Pestilence Master's Shroud (full set, 6 items): a ranged caster set, Blight-themed.

Grace of Inarius (full set, 6 items): a melee set (dubbed Meleemancer by the community ), Bone-themed.

There are six Necromancer sets, all of them level 70 only: Playstyles are extremely varied for the class. These do not count towards Wings of the Dedicated and Wings of Mastery, instead rewarding their own two pennants. Eventually, a total of 4 full sets was given, each complete with a Set Dungeon. The Necromancer originally had less than four Sets, to leave room for the community to come up with new playstyles and have those added onto new sets. The Necromancer avoids the slapstick humor of the Witch Doctor, as the Necromancer class is not meant to be funny. Necromancers have few Poison spells, and no damage over time attacks, as that is the prerogative of Witch Doctor to compensate, all Necromancer pets are controllable to some degree, unlike those of Witch Doctor. Witch Doctors are more lighthearted, while Necromancers are more dark and grim (using Curses, Blood, and Bone). While Witch Doctors and Necromancers share many similarities, Blizzard has noted a few differences. The player using the Necromancer will see the full effects of skill-use, while players in a party will see a more basic visual display. New technology has been developed for the Necromancer, as it's an effects-heavy class. The Necromancer is playable in both Campaign and Adventure Mode, fully voiced, and has new tomes to flesh out their backstory.

New achievements were implemented along with the Necromancer. To use the pack, one needs to have Reaper of Souls installed for PC or have the Ultimate Evil Edition for console. The pack was released on June 27 of 2017, and costs $14.99 USD in North America. The Necromancer is available in the Rise of the Necromancer pack, released at the same time as patch 2.6.0 came out.

The Necromancer's core stat is Intelligence.

As such, Convention of Elements is especially effective for Necromancers. The three Elemental Damage types are Poison (blight), Physical (blood and bone) and Cold (chill of the grave). In combat, they rely on bone and blood spells, Curses, Golems and undead minions.

Necromancers in Diablo III are very similar to the Diablo II class, and retain most of their skills.
