How to Summon the Scourge of Hatred

Before facing the Scourge, you’ll need to gather Corrupted Sigils and Hatred Hearts, obtained by:

Completing World Tier IV Corruption Events

Look for red corruption zones on the map.

Defeat elite mobs and complete rituals to collect Hatred Embers.

Crafting a “Totem of Bound Wrath” at the Occultist.

Combine:

5x Hatred Embers

3x Writhing Cinders (from Season 9 nightmare dungeons)

1x Exalted Bloodshard (drop from any Tier 50+ boss)

Enter the Sanctum of Malphas

Found beneath Hawezar’s Writhing Mire, marked only after totem use.

This becomes a timed-instance arena, only accessible for 15 minutes.

Recommended Requirements

You must be in World Tier IV to summon and fight the Scourge.

Minimum Stat Benchmarks (Solo or Group):

Character Level: 85+ (90+ ideal)

Gear Score: 780+

Resistances: Max Cold and Shadow resist

Armor: 7,000+ Physical Armor

DPS: Capable of 1M+ sustained per second

Build Preparation & Team Roles

Solo Players:

Bring burst damage builds (e.g., Twisting Blades Rogue, Pulverize Druid, Bone Spear Necro)

Focus on mobility, high sustain, and unstoppable uptime

Bring Elixirs of Shadow Resistance and Poison Cleanse

Group Composition:

1x Tank/CC support (e.g., Taunt Barb with Rallying Cry)

2–3x DPS with fire/holy skills (Scourge is weak to these)

1x Healer/cleanser (Poisonous Auras stack; clearing debuffs helps survival)

Phase-by-Phase Breakdown

Phase 1: Manifested Hatred (100%–70%)

The boss opens with Hatred Spikes, AoE trails that chase players.

Frequently summons Shadows of Malice (adds that explode on death).

Tip: Stack the adds and cleave for quick DPS windows, but stay spread out to avoid overlapping detonation damage.

Phase 2: Consumed Core (70%–40%)

The Scourge enters an aura phase, dealing constant Shadow damage over time.

Will cast Chains of Torment, pulling players toward spiked zones.

Introduces Corruption Pools—standing in them applies 5-stack damage debuff.

Tip: Use mobility cooldowns or Unstoppable to break chains. Move as a group to avoid pool overlap.

Phase 3: Apex of Wrath (40%–10%)

All previous mechanics continue, but in faster succession.

Hatred Pulses—map-wide shockwaves—must be dodged or absorbed with barriers.

The Scourge summons a Mirror Avatar, which must be DPSed down or it will explode for massive AoE.

Tip: Save ultimates for this phase. Mirror has only 15 seconds to be defeated.

Phase 4: The Final Brand (10%–0%)

Boss becomes immune for 5 seconds, then enrages.

Gains 50% attack speed, 100% movement speed.

DPS Check: You have 30 seconds to defeat it before it detonates and wipes the party.

Tip: Use any remaining potions, Elixirs, and Aspect procs. Group stuns can briefly pause the enrage timer.

Consumables & Buffs

Bring:

Elixir of Hatred Resistance – reduces Shadow/Poison DoT.

Potion of Bastion – activates barrier when health dips.

Incense of the Exorcist – grants minor resistance + CC reduction.

Loot Table & Rewards

Defeating the Scourge of Hatred grants:

Legendary Ring: Ashen Core

+20% damage to Shadow-enchanted enemies

+10% movement speed while Unstoppable

Trophy of Hatred (cosmetic backpiece with burning chains)

Unique Weapon Drops (class-specific, e.g., Malphas’ Brand for Sorcerers)

Season 9 Title: Hatredbreaker

Higher world-tier completions increase drop rates of unique items.

Extra Tips for Victory

Use Damage Reduction from Close Enemies gear—many attacks are melee-ranged.

Consider aspects like:

Aspect of Might – for defensive uptime.

Aspect of Retribution – stuns help control the boss’s mirrors.

Scroll of Escape won’t work—once inside the instance, it’s win or die.

Voice comms in group play help manage chain pulls and AoE spread.

Conclusion

The Scourge of Hatred represents the peak of Season 9 PvE difficulty in Diablo 4. With layered mechanics, punishing debuffs, and a brutal enrage timer, this fight is not meant to be casual. But with the right preparation, builds, and buy Diablo IV gold teamwork, you’ll walk away with powerful gear and the satisfaction of toppling a force that even Lilith feared.

So sharpen your blades, polish your runes, and dive into the Writhing Mire—you’ve got a Scourge to extinguish.
