In Path of Exile 2: Dawn of the Hunt, the unique weapon Blightreaver has quickly become a staple among chaos-focused builds and POE2 Currency wisp farming specialists. Known for its ability to corrupt enemies with stacking poisons and amplify damage over time effects, Blightreaver isn't just a weapon—it's a plague in blade form. In this guide, we'll walk you through how to obtain Blightreaver, how to build around it, and where it excels, including specific tips for conquering difficult areas and bosses like the Rotbloom Matron and Vile Grove Depths.

Step 1: How to Obtain Blightreaver

Blightreaver is a unique corrupted claw obtainable via:

Wispforging with Virulent Wisps in corrupted hunts

Drop chance from the Rotbloom Matron (found in Wraithrot Marshes, corrupted tier 3)

Rarely in Corruption Vaults, which appear after Hunt Rank 6 in corrupted zones

Chaos Offering Rituals at Altar Stones (a new crafting altar mechanic tied to corrupted loot)

When hunting for Blightreaver, your best bet is to stack Virulent Wisps, which boost both the damage and drop rate of chaos-related loot. You'll want to target corrupted maps with affixes like:

“+X% chance for corrupted bosses to drop unique chaos items”

“Increased chance to find corrupted chests”

“+1 additional chaos altar per zone”

Equip Wispfinder's Satchel and invest in your Hunt Tree's Corruption Specialization path for the highest chance of success.

Step 2: Blightreaver's Stats & Passive Effects

Blightreaver (Corrupted Claw)

Base Damage: 80–120 Physical (converts 60% to Chaos)

Attack Speed: Very Fast

+30% to Chaos Damage over Time Multiplier

Hits apply Viral Blight, a stacking poison effect (max 7 stacks)

Each kill grants 1 second of Unholy Frenzy, increasing attack speed and poison proliferation

Requires: Level 47, 134 Dex

Blightreaver is designed to scale poison, chaos DoT, and rapid multi-hits. The Viral Blight effect behaves like a hybrid of poison and chaos degeneration—it stacks rapidly with claws and triggers chain reactions in enemy groups.

Step 3: Building Around Blightreaver

Blightreaver works best in Assassin, Shadow, or Druid archetypes that favor damage over time, mobility, and chaos scaling. Here's a sample build outline for an Assassin Claw Poisoner:

Core Skills:

Viper Dance (Main skill): A high-speed melee combo that applies poison per hit.

Caustic Flurry: Secondary AoE clear for packs, enhanced by Blightreaver's poison spread.

Shadowmeld: Escape and reposition skill with poison nova burst when exiting stealth.

Wither Totem: Reduces chaos resistance of enemies in boss fights.

Support Gems:

Poison

Unbound Ailments

Increased Attack Speed

Void Manipulation

Deadly Ailments

Multistrike (for Viper Dance)

Passive Tree Focus:

Chaos Damage

Damage Over Time Multiplier

Claw Mastery (gain life on hit, increased attack speed)

Poison Duration and Effect

Evasion and Evasion Rating if going hybrid with Druid

Key Ascendancy Passives:

Toxic Precision (increased chance to poison and multiplier)

Unstable Currents (chance to spread poison on kill)

Predator's Grin (gain frenzy on chaos kill, syncs with Blightreaver's Unholy Frenzy)

Step 4: Clearing Levels Efficiently

Where Blightreaver Shines:

Corrupted zones (especially jungle, decay, or fungal-themed areas)

Horde-based encounters like Wisp Echoes or Hunt Swarms

Bosses with minions (you benefit from poison spread and Frenzy uptime)

Map Modifiers to Seek:

Increased poison effectiveness

Monster packs contain infected spores (increases chaos vulnerability)

Increased density or bonus wisp spawn chance

Avoid These Mods:

Poison immunity or reduced DoT

Reflect chaos damage

“Enemies cannot be inflicted with ailments”

To clear maps quickly:

Use Viper Dance as your main skill—dash into packs, apply stacks, and retreat.

When Blight stacks reach 3+, enemies begin melting passively.

Use Caustic Flurry when surrounded for AoE burst.

Deploy Wither Totem before major fights to reduce enemy resistance.

Use Shadowmeld when your health dips—its nova clears nearby poisoned enemies.

Step 5: Boss Strategy – Rotbloom Matron

The Rotbloom Matron is both the gatekeeper and one of the best sources for farming Blightreaver. She uses fungal decay fields, poison geysers, and summons corrupted nymphs.

Strategy:

Equip chaos resistance gear

Keep moving—her geysers deal high damage over time

Take out adds quickly to charge Unholy Frenzy

Use Wither Totem at spawn to soften her resistances

Dodge her “Bloom Burst”—a giant AoE that detonates poison stacks on you

Use Shadowmeld right before burst phases for survivability

Once defeated, she has roughly a 6–10% chance to drop a corrupted unique claw, with a 1–2% chance of that being Blightreaver (improved with Virulent Wisps).
