Diablo 4 best Necromancer build in Diablo 4 Season 1

The best Diablo 4 Necromancer build in Season 1 is called the ‘Corpse Explosion Necromancer’, after its most essential skill. Simply put, the idea is to quickly create a ton of corpses, then explode those corpses to deal extra damage. We’ll be using bone attacks to cast debuffs on opponents, which in turn makes them more vulnerable to Corpse Explosion damage.

Best skills for the Necromancer in Diablo 4 Season 1

• Bone Splinters (basic, bone): fires three bone splinters. This skill has a lucky hit rate of 17% and generates six essence, plus one more essence each subsequent time an enemy is hit by the same cast of Bone Splinter. 
• Bone Spear (core skill, bone): conjure up a bone spear that deals damage and pierces through enemies. This skill costs 25 essence and has a lucky hit rate of 50%.
• Corpse Explosion (corpse): detonate nearby corpses, dealing damage to all nearby enemies. This skill has a 40% lucky hit rate. 
• Blood Mist (macabre, blood): grants immunity for three seconds, thereby reducing movement speed by 20% and periodically dealing 2% damage to enemies. Blood Mist also heals you for a small percentage (depending on upgrades) of your max HP.
• Corpse Tendrils (corpse): veins burst from a corpse, pulling in enemies, dealing damage, and stunning them for three seconds. The corpse will not be consumed. This skill has a 20% lucky hit chance. 
• Bone Storm (ultimate, bone): conjures a swirling storm of bones, dealing damage for ten seconds.

This is the list of active skills needed for our best Diablo 4 Necromancer build, in the same order as they appear on the skill tree. Bone Splinters is mainly used to generate essence, while Bone Spear is your go-to damage skill. As the ultimate ability is also a bone skill, we’ll be able to take full advantage of any bone skill buffs.

It won’t take long before the ground is littered with usable corpses, but before you get to the detonation part, make sure you first use Corpse Tendrils to pull enemies together and cast negative effects on them. 

Diablo 4 Season 1 Necromancer build skill point distribution

• Bone Splinters: rank 1. Unlock Enhanced Bone Splinters for a 25% chance to fire two additional Bone Splinters (only works if you have 50 or more essence). 
• Bone Spear: rank 5. Use Enhanced Bone Spear for extra damage, and Supernatural Bone Spear to cast the vulnerable debuff on the first enemy hit (lasts three seconds).
• Hewed Flesh: rank 3. This passive skill grants a lucky hit effect: dealing damage has a 12% chance (when fully upgraded) to spawn a corpse. This chance is doubled when fighting a boss.
• Corpse Explosion: rank 5. Unlock the Enhanced upgrade to increase the skill’s radius, and the Plagued upgrade to deal 8% increased damage against slowed, vulnerable, or stunned opponents. 
• Blood Mist: rank 5. Unlock Enhanced and Ghastly Blood Mist too. The first will decrease the skill’s cooldown by two seconds whenever you trigger the overpowered effect, while the latter spawns one corpse per second while the skill is active. Skill points in an AoE damage (area of effect) ability are always well spent.
• Grim Harvest: rank 3. Fully upgraded, this passive generates 6 essence per consumed corpse, so it’s an amazing source of essence for this build. Unlock the Fueled by Death enhancement as well (rank 3) to deal 9% increased damage after consuming a corpse. 
• Corpse Tendrils: rank 5. Unlock Enhanced Corpse Tendrils to slow enemies by 50% before pulling them in. Unlock Plagued Corpse Tendrils to make enemies vulnerable for three seconds if they’re hit by this skill.
• Serration: rank 3. This increases critical hit rate for all your bone skills, based on the amount of essence you have. The following Compound Fracture and Evulsion upgrades are incredibly strong, but beware that they only work well if you have a high critical strike chance. 
• Bone Storm: rank 1. Make sure you unlock the two upgrades, Prime and Supreme Bone Storm, to receive damage reduction and an increased critical strike chance while Bone Storm is active.
• Ossified Essence: rank 1. Your bone skills deal 1% extra damage for every point of essence you possess above 50. 
• Book of the Dead – Iron Golem: sacrifice the Iron Golem to gain a 30% critical strike damage increase. 
• Book of the Dead – Skirmisher Skeleton Warriors: sacrifice the Skirmisher Skeletons for a 5% critical strike chance. Optional: combine this with the passive skills ‘Stand Alone’ (rank 1) and ‘Memento Mori’ (rank 3) to increase this effect by 60%.
• Book of the Dead – Cold Mages: sacrifice them for 15% more damage against vulnerable enemies.
• Unliving Energy (optional): your maximum essence is increased. At the cost of additional essence, your core skills deal more damage.
• Necrotic Carapace (optional): fortify a certain percentage of your base life whenever a corpse is formed by your skills or minions.

Here’s a handy skill point distribution table for the Diablo 4 Corpse Explosion Necromancer build in Season 1:

Skill	Points Spent
Bone Splinters	1
Bone Spear	5
Hewed Flesh	3
Corpse Explosion	5
Blood Mist	5
Grim Harvest	3
Corpse Tendrils	5
Serration	3
Bone Storm	1
Ossified Essence	1
Book of the Dead – Iron Golem	Sacrifice
Book of the Dead – Skirmisher Skeleton Warriors	Sacrifice
Book of the Dead – Cold Mages	Sacrifice
Unliving Energy	Optional
Necrotic Carapace	Optional

Most of the active skills in this Corpse Explosion Necromancer build in Season 1 should be fully upgraded. The enhanced Bone Splinters, Bone Spear, and Corpse Tendrils skills cast debuffs on our opponents. This triggers the extra damage from the Plagued Corpse Explosion upgrade. 

Remember the two things you absolutely don’t want to be without: corpses and essence. Blood Mist and Hewed Flesh will help you out with the first part. And Grim Harvest is an incredibly helpful way to instantly regain essence after every Corpse Explosion. If you’re having trouble regaining essence, try the Unliving Energy skill. Likewise, if your Necromancer has trouble staying alive, you should use the Necrotic Carapace passive. Take points from Blood Mist or Serration if needed.

Finally, you might be wondering where the minions are. Since this Diablo 4 Necromancer build in Season 1 doesn’t use skeletal warriors, skeletal mages, or golem minions at all, it’s best to sacrifice them in return for a good combat bonus. Skeletal mage mastery and skeletal warrior mastery (including reapers) aren’t considered in this build. However, it can be very helpful to use minions as a buffer between you and your opponents. Pairing it with the Supreme Army of the Dead ultimate skill for a prime army is a good choice. If you feel like you need that extra protection, don’t be in a rush to get rid of them.

Diablo 4 Necromancer build – best stats and gear in Season 1

As it improves skill damage, we can’t have too much intelligence for this Diablo 4 Necromancer build in Season 1. However, be sure to get a decent amount of willpower too, as it helps you regain essence. We’ll keep our weapon advice simple: go for the highest possible damage (probably a two-handed weapon).

As for the bonuses, look out for a critical strike boost and extra bonus damage based on status effects in particular. Any additional improvements to your core skill, corpse skills, and bone skills are very welcome. Finally, always consider gems. The main consideration here for the Necromancer is bulking out the class’s damage profile. We advise always using Rubies in armour gem sockets to give the class as much maximum life as possible. Diamonds are also a good pick as they offer resistance bonuses against multiple elements.

Is the Necromancer good in Diablo 4 Season 1?

To achieve the truly overpowered version of this Diablo 4 Necromancer build in Season 1, you need the Aspect of Explosive Mist. Not only does it create extra Corpse Explosions, but its own cooldown is dramatically increased whenever you do.

Remember the Ghastly Blood Mist upgrade? The explosion will even result in free corpses, setting you up for a pretty heated corpse-blasting streak. This makes the Corpse Explosion Necromancer a deadly wave of death in the latest Season of Diablo 4.

Once you get to the endgame, slotting Paragon Glyphs into the Paragon Board is essential. Use the Codex of Power to determine the best Aspects for your character’s Legendary or Unique armour, amulet, boots, pants, and gloves. Remember that Seasonal characters will have to work through the Diablo 4 Strongholds and Dungeons to earn back renown. This will grant you extra Diablo 4 healing potion charges, Paragon Points, and skill points in the Seasonal Realm.
