The Necromancer is one of the most powerful classes in Diablo 4 due to its summoning capabilities. You'll have the means to raise ghastly creatures to fight alongside you. Here's our Diablo 4 Necromancer Book of the Dead guide to help you with the undead minions that you can unlock, as well as their ideal upgrades.

Diablo 4 Necromancer Book of the Dead minions guide

The Diablo 4 Necromancer Book of the Dead mechanic becomes available fairly early in the campaign. However, most other minion options can only be unlocked as you level up further. You can open this panel by pressing Shift + C on a keyboard, or checking the appropriate tab once you've opened the character/abilities menu.

Likewise, it bears mentioning that there are particular groupings or categories: Skeletal Warriors, Skeletal Mages, and Golems. Each grouping has its own type of creature variants, as well as selectable perks.
