Build Introduction

This is the endgame version of original Summoner Necromancer build which requires the unique Ring of MendelnRing of Mendeln, as the entire build is designed around it! This build was curated in collaboration with SinityX, the first player to defeat Uber Lilith with a Summoner build, and GhazzyTV. We can both say we’ve optimized and fine-tuned this build to perfection!

While being able to run Tier 100 Nightmare Dungeon, as well as defeating Uber Lilith. The build is by far the best Necromancer build you can possible play during Season 1. It’s extremely fast & brings out brutally high damage numbers making it capable of killing Uber Lilith well before you reach level 100 even!

As a final note before we dive in to the details, the damage is exclusively coming from the Ring of MendelnRing of Mendeln. This means the damage is coming from you as the player and not your Skeletal Minions.

Build Requirements

Required Uniques

Since the build is entirely designed around Ring of MendelnRing of Mendeln, you’ll need that Unique Ring before you can follow this guide. The Ring itself is a random Unique and can’t be directly target farmed outside of opening jewelry boxes in Helltide events.

Before you get the ring, you can always play the initial Summoner Necromancer build.

Thankfully, the patch changes have improved the build in the form of better survival for our minions, as well as making the EssenceEssence Glyph more reliable for our damage output. The Amplify buff is very significant, however, the Aspect of Grasping VeinsAspect of Grasping Veins Critical Strike Damage nerf lowered it slightly.

Besides the Necromancer specific changes, we did receive a nerf to our armor through the Aspect of DisobedienceAspect of Disobedience change.

The 1.1.1 patch brought us some extra damage output as well as warmly welcomed minion survival buffs!

Malignant Hearts

The Season 1 theme introduces Malignant Hearts that provide build-altering bonuses. The hearts are divided into 4 categories, each with a color that needs to be socketed in the corresponding colored Malignant Socket on equipped jewelry. Wrathful Hearts are a special case due to their rarity, and can be placed in any Socket. 

Listed below are the Malignant Hearts that are useful for this build, ranked by importance. Stats displayed reflect what a Level 20 character would receive as a drop.

  • Caged Heart of the SacrilegiousCaged Heart of the Sacrilegious (Vicious, Offensive): Walking near a Corpse automatically activates an equipped Corpse Skill every second, dealing 40-30% reduced damage.

Book of the Dead

Since this is a pure Minion build, we’ll want to use our Minions instead of sacrificing them. However, since we are in need of other skills, the Golem just isn’t bringing enough power to be used.

  • Melee Skeletons: Reapers Skeletons; these will generate corpses for us to consume.
  • Mage Skeletons: Shadow Skeletons; we’ll take the extra shadow bolt option here to further trigger our ShadowblightShadowblight.
  • Golem: Iron Golem; you’ll want to sacrifice the Iron Golem to provide increased Critical Strike damage.


The Paragon progression system unlocks at Level 50, providing 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, 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. It’s very important to point out that to make this build work you’ll need to keep the minions alive, this is done with our sixth & final board “Cult Leader” in which we’ll use the DeadraiserDeadraiser Glyph to scale our damage reducing nodes for the minions. Due to the importance of this board it’s recommended to place this early on instead of the “Flesh-eater” board as you progress your character and later on when you’re higher level become able to swap places with the 2 boards you’ll do so.

Starting Board

Necromancer paragon board D4

The Starting Board is very straight forward; we’ll rush up on the right-hand side and get the socket in which we’ll socket the AmplifyAmplify Glyph. Remember to take the extra attributes within radius to get the bonus modifier from the Glyph if possible. The radius will increase as you level the Glyph up via Nightmare Dungeons. We’ll next head out north to our next board. Do ignore the first nodes on the left side of this board till you’ve collected all sockets from all our boards.

Scent of Death (2nd Board)

Necromancer paragon board D4

Our second Board is the Scent of Death Legendary Board. Remember, in order to match the image above, you may need to rotate the Paragon Boards. In this Board we’ll start by rushing the Legendary Node Scent of Death before taking the Magic and Rare nodes on our way to the socket, in which we’ll place the ControlControl Glyph. As with the Starting Board, take the extra attributes within radius if possible to get the bonus modifier out of the Glyph. Once done, we’ll briefly exit on the left side to get our third Board, Bone Graft, before coming back and exiting out of the north side to enter the Wither Board.

Bone Graft (3rd Board)

Necromancer paragon board D4

The third board, Bone Graft, we’ll rush the socket to place the ExploitExploit Glyph. As before, take extra attributes if the radius and level of the Glyph allows for the bonus modifier to be activated. Once done, we’ll head back to our second Board, Scent of Death, and head out on north.

Wither (4th Board)

Necromancer paragon board D4

Here we rush the socket slot, you’ll grab the surrounding Magic and Rare nodes as we make our way to the socket in which we’ll place the ScourgeScourge Glyph. Only take the extra attributes and Nodes around this Glyph if you have it leveled enough to enable the bonus modifier. If not you just path out on the left side for our 5th board being the Flesh-Eater.

Flesh-Eater (5th Board)

Necromancer paragon board D4

For Flesh-Eater, take all surrounding Magic and Rare as shown in the image, grabbing the socket first to place the EssenceEssence Glyph. Only take extra attributes around it to enable the bonus modifier, however, prioritize any and all Dexterity nodes within the Glyph radius to further scale our damage output. Once done, we’ll head out on the north side onto our final Paragon Board.

Cult Leader (6th Board)

Cult Leader is our bread & butter in keeping our Minions alive. The only reason for taking this board is to grab the Damage Reduction Nodes for our Minions, in combination with the DeadraiserDeadraiser Glyph, further scaling those modifiers.

Mechanics and Playstyle

This build is entirely designed around Ring of MendelnRing of Mendeln. We’ll want to stack Lucky Hit as much as possible on every single gear piece. This build will be abusing some niche mechanics, such as Bone PrisonBone Prison triggering Lucky Hits, at an almost obnoxious level.

The mechanic of the build is all centered around triggering Lucky Hits, and thanks to Bone PrisonBone Prison, the effect happens constantly. The Malignant Heart, Caged Heart of the Decrepit AuraCaged Heart of the Decrepit Aura, will automatically apply DecrepifyDecrepify onto your enemies. Meanwhile, the Caged Heart of the SacrilegiousCaged Heart of the Sacrilegious, will force Corpse skills to be used every second you’re near a corpse on the ground. Follow this up by placing Bone PrisonBone Prison onto nearby enemies and hop into Blood MistBlood Mist. Corpse TendrilsCorpse Tendrils will provide a consistent way of applying Vulnerable onto enemies, as well as stunning them and gathering them into one place. Everything up to this point is capable of triggering Lucky Hits, which in turn will trigger the Ring of MendelnRing of Mendeln‘s special effect. With the changes in Season 1, the playstyle of this build allows us to stay in Blood Mist form continually until the demon threat is gone!

Gear Choice and Stat Priority

Lucky Hit is absolutely crucial for this build to function, but at the same time this build craves Critical Strike Chance. The goal is 100% chance to Critical Strike, achieved by combining our Aspect Powers and the bonus Critical Strike Chance we get from our Supreme Bone StormSupreme Bone Storm. The Mendeln Summoner build ensures low cooldown rate through Lucky Hits, meaning it can consistently apply Vulnerable unto enemies through DecrepifyDecrepify, thus making stacking Vulnerable damage an ideal option.

  • Weapon: Royal EmeraldRoyal Emerald for +#% Increased Vulnerable Critical Strike Damage.

Elixirs and Health Potions

To gain an edge in your adventures, head to the Alchemist in Kyovashad and craft Elixirs that enhance your stats and experience gain for 30 minutes. Remember to gather the necessary crafting materials by foraging plants. Select an Elixir that provides the resistance you need most, or try the Assault ElixirAssault Elixir to boost your Attack Speed by 7%.

Return to the Alchemist again when you reach Level 20 and 30 to upgrade your potion. The extra healing is essential to survival.

For the endgame, it’s important to make sure you have the highest level health potion as well as an active elixir as it provides increased experience gained and can either compensate low resistances or increase your damage output in the form of attack speed.
