Infinimist Necromancer Endgame Build for Diablo 4 (Season 4)

Build Introduction

The first build to finish Tier 100 Nightmare Dungeons in the game just got better! This build guide will take you through the optimized version of the Exploding Shadow Mist Necromancer, also known as “Infinimist” or “Shadowblight Stacker”.

Keep in mind that this build is gear-sensitive to function properly. This build requires the X’Fal’s Corroded Signet to get proper single-target damage output and a combination of Cooldown Reduction modifiers on your gear, together with % Increased Lucky Hit Chance!

Playing the build without the Unique ring is theoretically possible, but it will make you have significantly less single-target damage output. If you lack this ring or the modifiers on gear listed in this guide the recommendation is to use any of the previous versions of this build till you have the proper items!

This build is a variant of both, the Sever and Blight Shadowmancer Necromancer:

Build Requirements

Required Uniques

X’Fal’s Corroded Signet

This build requires X’Fal’s Corroded Signet to deal proper single-target damage, without this unique it will feel a bit lackluster against bosses.

Skill Bar and Skill Tree Points

Recommended

Suggested Skill Bar

Blood Mist Blight Decrepify Corpse Tendrils Bone Storm Corpse Explosion

Follow the points allocated in the Skill Tree above for the complete 58-point build. The additional 10 skill points are completed using the Renown system.

Book of the Dead

Since we are focusing entirely on dealing brutal damage with our shadow skills, we have no interest in bothering with using our minions, so they will all be sacrificed in the name of Lilith.

• Melee Skeletons: Reapers; these are sacrificed for a great amount of extra Shadow damage dealt.
• Mage Skeletons: Cold Mages; this provides increased damage against Vulnerable targets.
• Golem: Iron; this gives us more damage output.

Paragon Board

The Paragon progression system unlocks at level 50 and provides a vast amount of character power. On the Paragon Board, bonuses range from minor stats on Magic Nodes to more powerful Rare Glyphs and Legendary Nodes.

As you path towards Glyph Sockets and Legendary Nodes, you should prioritize Damage, Intelligence, Resistance, and Life for Normal and Magic Nodes. Glyph radius increases as you level them up. Therefore, if you cannot fulfill Additional Bonus requirements early on, skip allocating extra nodes for now. It’s also important to point out that you might not have the Glyph you want when you reach your first socket; if that’s the case, simply slot in any Glyph providing any beneficial stats for you until you get the correct one.

Listed below are images of the pathing you should take along with the locations of the Glyphs and order you should choose your Paragon Boards past the initial Starting Board. Also, note that the Glyph radius is based on level 21 Glyphs.

1. Starting Board

The Starting Board is very straight-forward: You’ll want to focus on picking up the Rare nodes and only taking the extra pathing to fulfill the desired attributes required to benefit from the Additional Bonus modifier of the Amplify Glyph when it’s high enough level to achieve that. Any extra attribute nodes should be ignored unless they serve the purpose of that.

2. Wither

Make sure to rotate Wither to fit the image above. The first thing we’ll want to do here is grab the Wither Legendary Node then rush the socket and put in the Exhumation Glyph. Similar to our Starting Board, we’ll only take the extra attributes if they are within radius, and can fulfill the Additional Bonus requirement of the Glyph. After this, we will ignore the north exit till later and focus on heading out on the right-hand side to Flesh-Eater.

3. Flesh-Eater

For Flesh-Eater we want to rush the Legendary Node. You will head towards the socket on your way to the node and use the Territorial Glyph. Same story as always: don’t take the extra attributes unless the Glyph level is high enough to cover the required attributes within range! Next up we skip the Rare and Magic Nodes on the right side and instead save them for our last Paragon Points, as it is more important to head down south and connect Scent of Death.

4. Scent of Death

Scent of Death is just as straight-forward as our previous boards. We will first want to rush the Legendary Node, then grab the socket and put in a Sacrificial Glyph and, as per usual, only take the extra attributes if the Glyph level allows for it within its radius. Once this is completed, we will head back to Wither, as we want to head out north from that one and connect Cult Leader.

5. Cult Leader

Cult Leader is here to serve but one purpose: another Glyph. So we will therefor rush the socket and use the Control Glyph and grab the surrounding nodes required to enable the bonus modifier from the Glyph itself. Once done we’ll head back to our Flesh-Eater Board as we are now heading out on the right side from that board.

6. Bloodbath

Our final board is the Bloodbath Board. Similar to our previous board in this guide we are strictly here to make use of yet another Glyph to further scale our damage efficiency. We’ll rush the socket in which we use the Scourge Glyph and as per usual; grab any required attributes within range if the level of the Glyph allows for it to be done within the radius. After this, you’ll simply fill out any extra nodes you’ve skipped in any of the previous boards as you progress to Level 100. Happy hunting!

Gear, Gems, Elixirs, and Stats

The Season of Loot Reborn brings us an incredible shift in how gear and itemization are done. It is a major and will affect the game beyond Season 4’s confines. For further details, make sure to read our Tempering and Masterworking section below.

Legendary Aspects

Each aspect is listed with its matching gear slot. Do your best to keep each aspect in the assigned slot. Additionally, if you are trying to farm a specific item, we recommend using your Obols to target farm them!

Weapon Gems	Armor Gems	Jewelry Gems

Which Elixirs Should You Use?

Visit the Alchemist and craft an Elixir providing any Resistance you need most, or the Elixir of Advantage to increase Attack Speed. Some Elixirs cannot be crafted and only drop from things like Helltides or Nightmare Dungeons. Additionally, make sure to keep your health potion upgraded!

Stat Priority and Tempering Affixes

Affixes on the same line are considered to be equally important. Bolded affixes are the most important targets for Masterworking upgrades.

Slot	Targeted Gear Affixes	Tempering Affixes
Helm	1. Lucky Hit Chance 2. Cooldown Reduction 3. Ranks to Crippling Darkness	Profane Cage: Ranks to Crippling Darkness Profane Innovation: x% Decrepify size
Chest	1. Ranks to Blood Mist 2. Armor 3. Maximum Life	Profane Cage: Ranks to Crippling Darkness Profane Innovation: x% Corpse Tendrils Size

Keep in mind that the maximum Resistance is 70% by default for each element and can be increased to 85% by various sources.

Rotation and Playstyle

The main focus is to make sure you have as much damage over time effects on the target(s) as possible. Essentially you’ll want to cast Blight, Corpse Tendrils, Corpse Explosion and keep your Bone Storm active before you jump in to Blood Mist. However, thanks to your legendary aspect powers you will provide Corpse Explosions via your Blood Mist so if you ever need to get out of harm’s way or feel like you’re getting swarmed, you should always skip applying your skills and just jump into Blood Mist. All this AFTER you’ve applied Decrepify, making sure the enemies are cursed is fundamental for this builds functionality!

Make sure to check out the advanced Build Mechanics section for a more in-depth description of how the build works, what synergies exist, and what to look out for.

Uniques and Uber Uniques

Below you will find information on Uniques and Uber Uniques that are useful for this build. Moreover, if you are interested in target farming Uber Uniques, check out our How to Farm Uber Uniques guide.

Uniques

Listed below are the recommended and optional Unique Items for this build. This build thrives of the legendary aspect powers so we would prefer not to involve any uniques to have the build function the best. This doesn’t mean you can’t play around with some changes and test it out yourself though!

• Black River is a solid choice for more consistent DoT play at the cost of high burst damage outputs as you’ll rather focus on pure damage output over critical strikes using this weapon. It’s ok to use but not something we recommend.
• Harlequin Crest will be a great asset to the build but will replace one of your defensive aspects to fit, make sure you feel comfortable with the defensive layers the build provides before equipping this.
• Howl from Below is a fun pair of gloves, making your corpse explosions stand up and move to the enemies before exploding! Once you have crit scaling on your character, this is not to be recommended, but before that, these gloves are a great asset!

Season 4: Loot Reborn

The following list details the changes in the Season 4 Update (Patch 1.4.0) that may pertain to the Summoner Necromancer build. Check the Changelog for all the other guide updates. As you can see, only 1 change affected the build directly, and it’s a good one!

• Blood Mist movement speed reduction is now removed.

Video Guide

Advanced Information

Below, you will find every additional piece of information you need to know for a more in-depth look at this build.

Build Mechanics

The build focuses entirely on creating multiple hits with damage over time effects relying on Lucky Hits to create bursts of damage via both the Shadowblight Key Passive node and the unique ring X’Fal’s Corroded Signet. Having enemies cursed allows for a crazy amount of cooldown reduction via the Abhorrent Decrepify node, this is how we make the build essentially stay in Blood Mist form for the majority of the time playing the build.

The Blood Mist will trigger Corpse Explosion and when you are not required to use Blood Mist you can cast Corpse Tendrils and Blight for even more damage output.

Defenses

Making sure your resistances are capped and high damage reduction on top of armor via your gear and legendary aspects this build thrives on doing tons of lucky hits lowering the cooldown of your abilities. This allows you to stay inside Blood Mist form almost all the time which makes you literally immortal.

Offenses

Ramping up Shadow damage with consistent hits is the name of the game. The Shadowblight Key Passive and the unique ring X’Fal’s Corroded Signet are our main sources of damage triggered by all our damage over time sources we throw on the enemies!

Paragon

The recommended Paragon boards for this build are listed above, and further down below, you can find a more thorough route for allocating the Paragon points, as well as some notes on why specific nodes were chosen and why they are essential for this build.

Glyphs & Legendary Nodes	Effect
Amplify	– Grants +150% bonus to all Magic Nodes within range. – Additional Bonus is unlocked with 40 intelligence in radius making enemies affected by your Curses take an additional x10% increased damage from you and your minions.
Exhumation	– For every 5 Intelligence purchased within range, your Corpse skills deal x% increased damage. – Additional Bonus is unlocked with 40 intelligence in radius, consuming a corpse fortifies you for 4% of your maximum life and grants 4% damage reduction for 4 seconds.
Territorial	– For every 5 Dexterity purchased within range, you deal 10% increased damage to Close targets. – Additional Bonus is unlocked with 25 Dexterity in radius, you gain 15% damage reduction against Close targets.
Sacrificial	– Grants +150% bonus to all Magic nodes within range. – Additional Bonus is unlocked with 40 Intelligence in radius, you deal x10% increased damage while you have no active minions.
Control	– For every 5 Intelligence purchased within range, you deal 10% increased damage to Crowd Controlled Targets. – Additional Bonus is unlocked with 40 Intelligence in radius making you and minions deal x20% increased damage to Crowd Controlled targets.
Scourge	– For every 5 Intelligence purchased within range, you deal x% increased Shadow damage over time. – Additional Bonus is unlocked with 40 Intelligence in radius, you and your minions deal x10% increased damage to enemies affected by Shadow damage over time effects.
Wither	Your Shadow damage over time effects have x5% chance to deal x50% bonus damage each time they deal damage. This chance is increased by x1% and bonus damage is increased by x4% for each 60 Intelligence you have.
Flesh-eater	Consuming 5 Corpses grants x40% increased damage for 6 seconds.
Scent of Death	With at least 2 Corpses Nearby, you gain 15% Damage Reduction. With no Corpses Nearby, you deal x15% increased damage.

Let’s take it one step further and break down each of the beneficial nodes we spend our Paragon Points on:

Starting Board

1. Amplify We mainly grab this Glyph for the additional bonus effect which is easy to unlock on the starting board.

Wither

1. Exhumation is yet again a Glyph chosen for the ease of access to unlock the bonus modifier, in the higher levels you’ll want to pick up the remaining attributes in range to further scale this Glyph!
2. Wither This legendary node is the name of the game for the build to further scale our damage output.

Flesh-Eater

1. Territorial Glyph makes perfect sense as we are more often than not close to our enemies, on the Flesh-Eater board it’s very easy to enable the bonus modifier as well.
2. Flesh-eater Considering how many corpses this build is consuming on a regular basis this node is a logical choice!

Scent of Death

1. Sacrificial Glyph provides increased power from our Magic nodes in radius but we are mainly taking this glyph on the board for the bonus modifier.
2. Scent of Death is similar to our previous board with the idea of corpse consuming, we are always going to be near a corpse making this a solid legendary node to grab.

Cult Leader

1. Control Similar to previous boards we are running through our paragon board to chase bonus modifiers from all our glyphs.

Bloodbath

1. Scourge Yet another glyph mainly taken for the bonus modifier.

Tempering and Masterworking

The Season 4 update (Patch 1.4.0) introduces a rework for itemization. Tempering and Masterworking bring the biggest change to itemization since the release of Diablo 4, so make sure you understand the new systems explained in this section.

The amount of affixes on items has been changed to reflect its rarity: Normal Items have no affixes, Magic Items have 1 affix, Rare Items have 2 affixes, Legendary Items have 3 affixes, and Unique Items have 4 affixes. Upgrading a Rare Item to a Legendary Item by imprinting a Legendary Aspect from the Codex of Power will not add a third affix. Therefore, Legendary Items are superior to lower rarity items for a min-maxed character.

Greater Affixes are a newly added mechanic that increases the value of an affix by 50%. Ancestral Legendary Items and Unique Items can now drop with up to 4 Greater Affixes! Search for items with your preferred Greater Affixes to upgrade with Tempering and Masterworking.

Tempering and Masterworking is an important system, even mandatory in the endgame, for character progression. You are able to add 2 additional affixes on any Rare Item or Legendary Item, exclusive to the Tempering System. An Ancestral Legendary Item can have up to 5 total affixes! Unfortunately, Unique Items cannot be tempered to add affixes.

Masterworking uses new crafting materials found in The Pit to further enhance the stats of an item. These upgrades can be applied on an Ancestral Legendary Item that has its Tempering Slots filled out. Unique Items can be upgraded with Masterworking right away, as tempering does not apply to them. Each item has 12 upgrade slots. On upgrade Ranks 4, 8, and 12, a random affix is increased in value by 25%. Every other upgrade Rank applies a 5% increase to all affixes on an item. Attempt to apply the bonus 25% upgrade to your preferred affix multiple times by resetting the Masterworking Ranks to repeat the process.
