Diablo 4 Necromancer Unique Class Mechanic

Diablo 4’s Necromancer class has a unique class mechanic called the Book of the Dead, which allows players to customize their army of undead minions.

There are three types of minions the Necromancer can summon, including Skeletal Warriors, Skeletal Mages, and Golems. If you faced the problem where Necromancer’s Golem wouldn’t spawn, the solution is provided in this article. Each minion type has its own specializations, such as combat behavior or types of magic. For instance, Skeletal Warriors can be specialized as Skirmishers for higher damage or as Defenders for increased life. Skeletal Mages, on the other hand, can choose between three types of magic: Shadow, Cold, and Bone. Additionally, each minion type has upgrades that will synergize with the Necromancer’s skills.

Lastly, players can use the Book of the Dead to sacrifice the ability to access certain minion specializations and receive a permanent buff in return. Some examples of these buffs include a permanent 15% gain to non-Physical damage resistance for Skeletal Warriors’ Defender specialization and a permanent 15% increased damage bonus against Vulnerable enemies for 3 seconds for Skeletal Mages’ Cold specialization.

Necromancer Skills in Diablo 4

The Necromancer has several skill groups to choose from, including Basic Skills, Core Skills, Corpse and Macabre Skills, Corruption Skills, Summoning Skills, Ultimate Skills, and Key Passives.
