Mendeln Summoner Necromancer Endgame Build for Diablo 4 (Season 1)


Discover the ultimate endgame version of the Summoner Necromancer build for Diablo 4, specifically designed around the unique Ring of Mendeln. This build has been optimized to perfection in collaboration with SinityX, the first player to defeat Uber Lilith with a Summoner build, and GhazzyTV. It offers unparalleled speed and devastating damage, making it the top choice for Season 1.

Build Requirements

Before diving into the details, it’s important to note that you will need the Ring of Mendeln for this build to work effectively. Unfortunately, the ring is a random unique item that can only be obtained by opening jewelry boxes in Helltide events. In the meantime, you can still play the initial Summoner Necromancer build.

Patch 1.1.1

  • Increased the damage for Aspect of Decay from 20-40% to 25-45%.
  • Reduced the damage dealt to Druid Companions and Necromancer Minions by the following attacks:
    • Balrog’s Fire Breath
    • Elite Affixes: Fire Enchanted, Electrified Obelisks, Shock Lance

These changes have improved the damage output of our minions, enhancing the build’s survival and making the Essence Glyph more reliable for damage. The Aspect of Grasping Veins Critical Strike Damage nerf slightly reduced its effectiveness. Additionally, the Aspect of Disobedience change reduced the maximum Bonus Armor %.

Malignant Hearts

The Season 1 theme introduces Malignant Hearts that provide build-altering bonuses. Each heart belongs to a specific category and needs to be socketed in the corresponding colored Malignant Socket on equipped jewelry. Here are the Malignant Hearts useful for this build, ranked by importance:

  1. Caged Heart of the Sacrilegious (Vicious, Offensive): Walking near a Corpse automatically activates an equipped Corpse Skill every second, dealing 40-30% reduced damage.
  2. Caged Heart of The Barber (Wrathful, Super-World Tier III): Critical Strikes and subsequent damage within 2.0-4.0 seconds are absorbed by your target, then erupts onto surrounding enemies. Stored damage increases by 10% per second.
  3. Caged Heart of the Decrepit Aura (Brutal, Defensive): When at least 5 enemies are near you, gain an aura that automatically curses surrounding enemies with Decrepify for 5-15 seconds.

Skill Tree Points and Skill Bar

Book of the Dead

As a pure Minion build, we prioritize using our Minions instead of sacrificing them. However, the Golem doesn’t provide enough power for this build. Here’s how we allocate our skill points:

  • Melee Skeletons: Reapers Skeletons generate corpses for consumption.
  • Mage Skeletons: Shadow Skeletons with the extra shadow bolt option to trigger Shadowblight.
  • Golem: Iron Golem sacrificed to provide increased Critical Strike damage.

The Paragon progression system unlocks at Level 50, granting significant character power. Prioritize Damage, Intelligence, and Life for Normal and Magic Nodes as you path towards Glyph Sockets and Legendary Nodes. Level up Glyphs to increase their radius. Remember, you may not have the desired Glyph when you first reach a socket, so use any beneficial Glyph until you find the correct one. Here are the recommended paths and Glyph locations for the Paragon Boards:

  • Starting Board: Rush the right-hand side for the socket and place the Amplify Glyph. Take the extra attributes within the radius for the bonus modifier from the Glyph.
  • Scent of Death (2nd Board): Rush the Legendary Node Scent of Death, take the Magic and Rare nodes, and place the Control Glyph in the socket.
  • Bone Graft (3rd Board): Rush the socket and place the Exploit Glyph. Take extra attributes if the Glyph radius allows for the bonus modifier.
  • Wither (4th Board): Rush the socket and take surrounding Magic and Rare nodes. Place the Scourge Glyph in the socket, taking extra attributes if the Glyph is leveled enough for the bonus modifier.
  • Flesh-Eater (5th Board): Take all surrounding Magic and Rare nodes. Place the Essence Glyph in the socket, prioritizing any Dexterity nodes within the Glyph radius to scale damage output.
  • Cult Leader (6th Board): This board is crucial for minion survival. Take the Damage Reduction Nodes for minions using the Deadraiser Glyph to further scale the modifiers.

Mechanics and Playstyle

The core of this build revolves around the Ring of Mendeln. The goal is to stack Lucky Hit on every gear piece. Bone Prison triggers Lucky Hits, making it a vital mechanic in this build. The playstyle involves constantly triggering Lucky Hits, which, in turn, triggers the Ring of Mendeln’s special effect. Here’s how to execute the playstyle:

  1. Use the Malignant Heart, Caged Heart of the Decrepit Aura, to automatically apply Decrepify to enemies.
  2. Utilize the Malignant Heart, Caged Heart of the Sacrilegious, to force Corpse skills to be used every second when near a corpse on the ground.
  3. Place Bone Prison on nearby enemies and activate Blood Mist.
  4. Use Corpse Tendrils to consistently apply Vulnerable to enemies, stunning them, and gathering them in one place.
  5. The combination of Lucky Hits, Bone Prison, and Corpse Tendrils triggers the Ring of Mendeln’s special effect.
  6. Thanks to the Season 1 changes, you can stay in Blood Mist form continuously until the demon threat is eliminated.

  • Vulnerable Damage
