Diablo III: Rise of the Necromancer

Diablo III: Rise of the Necromancer is a dark-fantasy action role-playing downloadable content (DLC) character pack developed and published by Blizzard Entertainment. Released on June 27, 2017, for Microsoft Windows, macOS, PlayStation 4, and Xbox One, the pack was later bundled into the definitive Diablo III: Eternal Collection retail and digital editions across all home systems, including the 2018 Nintendo Switch port.

Launched alongside Patch 2.6.0, the DLC marks the formal return of the fan-favorite Necromancer class—the Priests of Rathma—from Diablo II. The pack re-engineers their classic summoner and dark magic identity to integrate with Diablo III’s modern, freely swappable skill matrix and high-velocity combat environment.

Technical Specifications

Class Mechanics: Blood, Bone, and Essence

The Necromancer features a macabre, highly active playstyle centered around tactical resource generation and spatial battlefield awareness. Unlike other magic classes that rely on auto-regenerating mana, the Necromancer governs two independent structural assets:

1. Essence Tracking

Essence is the primary magical fuel used to cast baseline projectile spells and high-tier area-of-effect bursts. It does not naturally decay or replenish over time. Instead, players must actively siphon it from enemy targets using basic primary generation strikes (such as Grim Scythe or Bone Spikes).

2. The Corpse Matrix

The class’s defining secondary resource loop is the Corpse System. When monsters are slain on the battlefield, they drop a visible, glowing physical body mapped exclusively to the Necromancer’s game screen. These corpses are finite and serve as fuel for the class’s most powerful abilities:

• Corpse Explosion: Detonates up to five targeted bodies simultaneously, turning enemy remnants into high-damage physical shrapnel traps.
• Corpse Lance: Telekinetically extracts shards from dead bodies to fire rapid, high-velocity armor-piercing bone spikes at a single target.
• Devour: Forcefully consumes surrounding corpses from a distance to immediately replenish massive blocks of Essence and Health mid-combat.

Playstyles & Skill Runes

The Necromancer’s swappable skill slots map across three thematic philosophies, which can be modified using elemental Skill Runes:

                          [The Priest of Rathma]
                                    |
       +----------------------------+----------------------------+
       |                            |                            |
 [Reanimation]                   [Blood Magic]               [Bone Spells]
• Command Skeletons             • Sacrifice Health           • Bone Armor Shields
• Skeletal Mages                • High Damage Buffs          • Bone Spear Projectiles
• Revive Hostile Dead           • High-Mobility Teleports    • Crowd Control Stuns

• Reanimation (The Pet Build): Relies on absolute army micromanagement. Passive skeletons automatically rise from the ground to defend the caster, while active commands force them to focus-fire elite targets. High-tier summons include massive Skeletal Mages and the ability to Revive a pack of fallen monsters to fight for the player.
• Blood Magic (The Glass Cannon Risk): Trades physical sustainability for immense burst windows. Specialized blood runes force skills to consume a direct percentage of the Necromancer’s own health pool instead of Essence, granting massive damage multipliers and instant mobility options (like Blood Rush).
• Bone/Physical (Tactical Control): Focuses on close-range defenses and crowd control. The class rips bone fragments from surrounding targets to forge Bone Armor, wraps battlefield boundaries in Bone Spikes, and launches long-range Bone Spears down linear corridors.

“Balance must be preserved at all costs. The Priests of Rathma see neither good nor evil in their actions—simply obedience to the eternal cycle of being.” — Rathmaic Theological Lore

Pack Inclusions & Features

Beyond unlocking the character class, the Rise of the Necromancer pack functions as an account-upgrade bundle, introducing various mechanical utility and vanity items:

• The Complete Necromancer Hero Class (Male and Female models with full voice-over dialogue tracks).
• +2 Additional Character Slots to support an expanding roster of seasonal heroes.
• +2 Additional Stash Tabs to provide extra private item storage (PC and Mac platforms only).
• The Wings of the Crypt Guardian cosmetic back piece item.
• The Half-Formed Golem Pet, an automated companion that follows the hero across maps to fetch dropped gold coins.
• Exclusive Heraldry Cosmetic Set (Necromancer-themed Banner Shape, Banner Sigil, Portrait Frame, and Pennant).

Reception and Modern Legacy (2026)

Upon its initial 2017 launch, Rise of the Necromancer received generally favorable reviews from strategy and action RPG critics, holding a composite score of 76/100 on review aggregator Metacritic. Outlets like IGN presented an 8.5/10, heavily praising the mechanical creativity of the corpse-fueled economy and finding it a highly satisfying nostalgia trip that improved on Diablo II’s baseline reanimation models. Minor criticisms targeted the pack’s $14.99 pricing structure, which some players felt was slightly steep for a single character class devoid of an accompanying story Act or geographic map expansion.

Current Preservation Status

As of 2026, Rise of the Necromancer is no longer distributed exclusively as a standalone premium add-on. It serves as a core baseline component built natively into the global digital installer for the Diablo III: Eternal Collection across all modern systems.

Even with the game operating in its automated maintenance era (with Season 38 actively running as of March 2026), the Necromancer remains an elite meta-game pick for high-tier competitive Greater Rift leaderboards. The class’s top-performing gear sets, such as Bones of Rathma and Trag’Oul’s Avatar, dynamically scale with current seasonal modifiers, like the Season of Ethereal Memory.

The client runs smoothly under modern multi-core Windows 11 architectures and current console generations, scaling seamlessly into native 4K ultra-widescreen desktop resolutions with perfect frame rates, fully preserving the dark arts of the Priests of Rathma for modern ARPG purists.
