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 SignetX’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 SeverSever and BlightBlight Shadowmancer Necromancer:

Blight Shadowmancer Necromancer Sever Shadowmancer Necromancer

Build Requirements

Required Uniques

This build requires X'Fal's Corroded SignetX’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

Suggested Skill Bar
Blood Mist Blood Mist Blight Blight Decrepify Decrepify Corpse Tendrils Corpse Tendrils Bone Storm Bone Storm Corpse Explosion 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 AmplifyAmplify 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 TerritorialTerritorial 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 SacrificialSacrificial 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 ControlControl 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 ScourgeScourge 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

Which Elixirs Should You Use?

Visit the Alchemist and craft an Elixir providing any Resistance you need most, or the Elixir of AdvantageElixir 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

Below are the affixes to prioritize on gear. Each line of affixes is listed in order of importance. Tempering Manuals and their recommended affixes are provided in the second column, and the bolded affixes are the most important targets for Masterworking upgrades.

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 BlightBlight, Corpse TendrilsCorpse Tendrils, Corpse ExplosionCorpse Explosion and keep your Bone StormBone Storm active before you jump in to Blood MistBlood 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 DecrepifyDecrepify, 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 RiverBlack 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 CrestHarlequin 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 BelowHowl 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 SignetX’Fal’s Corroded Signet. Having enemies cursed allows for a crazy amount of cooldown reduction via the Abhorrent DecrepifyAbhorrent Decrepify node, this is how we make the build essentially stay in Blood MistBlood Mist form for the majority of the time playing the build.

The Blood Mist will trigger Corpse ExplosionCorpse Explosion and when you are not required to use Blood Mist you can cast Corpse TendrilsCorpse Tendrils and BlightBlight 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 MistBlood 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 ShadowblightShadowblight Key Passive and the unique ring X'Fal's Corroded SignetX’Fal’s Corroded Signet are our main sources of damage triggered by all our damage over time sources we throw on the enemies!

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

Starting Board

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

Wither

  1. ExhumationExhumation 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. WitherWither This legendary node is the name of the game for the build to further scale our damage output.

Flesh-Eater

  1. TerritorialTerritorial 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-eaterFlesh-eater Considering how many corpses this build is consuming on a regular basis this node is a logical choice!

Scent of Death

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

Bloodbath

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