Best Diablo 4 Bone Spirit Necromancer endgame build guide

With the official release of Patch 1.1.1, Diablo 4 Season of the Malignant has received plenty of changes and balances to enhance the gameplay experience. After the rather disappointing Patch 1.1.0, people seem to be quite happy with the latest update. However, this new set of class balance changes is significantly important to the Bone Spirit Necromancer build.

Since the release of Diablo 4 on June 6, 2023, the Necromancer has been one of the most played classes in the game. However, it has recently been on the receiving end of a fair share of nerfs. Hence, some of the strongest builds, such as the Bone Spear or the Bone Spirit, have been weakened a bit. Nevertheless, they can perform admirably in the title.

Best skills to unlock for the Bone Spirit build in Diablo 4

Quite unsurprisingly, the Bone Spirit and the Bone Spear Necromancer build are quite similar in their basic structuring. However, with Bone Spirit being the prime skill for this build, you will have to incorporate many other important skills such as Reap, Bone Spear, and Bone Storm. Alongside Bone Spirit, you will completely max out these skills to make your Skill Tree formidable.

Here is the complete list of skills that you will have to unlock:

Reap, Enhanced Reap, Acolyte's Reao
Bone Spear x5, Enhanced Bone Spear, Paranormal Bone Spear
Hewed Flesh x3 (Passive)
Corpse Explosion x1, Enhanced Corpse Explosion, Blighted Corpse Explosion
Grim Harvest x3 (Passive)
Death's Embrace x3 (Passive)
Bone Spirit x5, Enhanced Bone Spirit, Ghastly Bone Spirit
Reaper's Pursuit x3 (Passive)
Crippling Darkness (Passive)
Corpse Tendrils x1, Enhanced Corpse Tendrils, Blighted Corpse Tendrils
Serration x3 (Passive)
Compound Fracture x3 (Passive)
Evulsion x3 (Passive)
Bone Storm, Prime Bone Storm, Supreme Bone Storm
Stand Alone x2 (Passive)
Memento Mori (Passive)
Ossified Essence (Key Passive)

There should be a few more remaining renown points that you would be able to spend in your Diablo 4 Necromancer Skill Tree. You can use them to acquire Blood Mist and Fueled by Death (Passive) or get the max upgrades to the Memento Mori passive.

For the Book of the Dead choices, we will be sacrificing all the minions to gain the most damage output in the Bone Spirit Necromancer build in Diablo 4 Season of the Malignant.

Paragon Board for Bone Spirit Necromancer build in Diablo 4

As you must have known, once you reach Level 50, you will no longer be able to upgrade your Skill Tree as you stop receiving Skill Points. Instead, you will receive Paragon Points, with which you can start upgrading your Paragon Board and gain the essential buffs.

In the first board, your primary glyph should be the Exploit glyph. Besides focusing on Maximum Life and Damage Dealt, the Exploit glyph will increase your damage against Vulnerable enemies.

However, the second board is where things get a bit interesting. Pick up the Bone Graft board and make your way to the Legendary Node (rotate it for easy access). Make sure to use the Essence glyph and upgrade it thoroughly by completing Nightmare Dungeons and picking up Dexterity points in Diablo 4.

As we move toward the Diablo 4 endgame, pick up the Scent of Death and Flesh Eater as your third and fourth boards. Ideally, rotate these boards to get their Legendary Nodes as soon as possible and equip them with the Imbiber and the Blood Drinker glyph, respectively.
