Path of Exile 2: How to Get the Plague Siege Gemini Bow

 

The Plague Siege Gemini Bow is one of the most coveted weapons for Dexterity-based builds in Path of Exile 2, thanks to its unique affix pool and synergy with Poison, Bleed, and POE2 Currency Chaos-damage over time effects. Whether you're building a Deadeye poison barrage specialist or a Pathfinder with chaos scaling, this bow delivers elite endgame performance and flexibility. But acquiring it isn’t straightforward—it requires knowledge of where it drops, how to target-farm it, and how to optimize it with the new crafting systems in POE 2.

 

In this guide, we’ll break down everything you need to know about how to get the Plague Siege Gemini Bow, from its base type and drop rate to targeted farming, vendor recipes, and how to craft your ideal version.

 

What is the Plague Siege Gemini Bow?

Base Type: Gemini Bow

The Gemini Bow is a high-level dexterity-based weapon with solid base attack speed and dual implicit modifiers. In Path of Exile 2, the Gemini Bow class stands out because it allows for hybrid scaling: one implicit often boosts Chaos or Poison, while the other may enhance Critical Strikes, Projectiles, or Bleeding. The Plague Siege is a rare or unique version of this bow class and is especially potent in builds that stack Poison or Chaos over Time.

 

Why Use Plague Siege?

The Plague Siege version typically comes with:

 

High base Physical or Chaos damage

 

Additional Chaos Damage over Time multiplier

 

Faster Projectiles or Attack Speed

 

Implicit chance to inflict Withered on hit or Poison stacks

 

These features make it perfect for DoT (damage over time) archers and hybrid builds relying on ailments or chaos scaling.

 

Where Does Plague Siege Drop?

1. High-Level Maps (Tier 10+ and Endgame Atlas Regions)

Plague Siege is a rare drop found in high-tier maps, particularly in Chaos-aligned zones or regions featuring poison/ailment-focused enemies. The best drop rates are reported from:

 

Viridian Wastes – A new Atlas region introduced in POE 2 that features nature-infested, corrupted enemies.

 

Plagued Aqueduct – A corrupted version of the classic Aqueduct zone where chaos and poison-themed mobs are common.

 

Players report that the Plague Siege Gemini Bow is not part of the global drop pool until you’re map level 78 or higher. Drop rates spike when running content with increased rarity and pack size modifiers.

 

2. Chaos & Poison Themed Bosses

Specific bosses are known to drop Plague Siege or increase your chances:

 

The Venom Warden (Viridian Map Boss)

 

Queen of Spores (Endgame Map)

 

Putrescent Horror (Delve Boss in Chaos Biome)

 

These bosses have loot tables weighted toward Chaos and DoT-themed weapons, including the Gemini Bow base.

 

3. Delve Chaos Biomes (Depth 150+)

Deep Delve nodes, especially in Abyssal Depths or Chaos Fossil biomes, offer higher chances to drop Gemini Bows with Plague or Poison affixes.

 

Use Corroded, Dense, and Aberrant Fossils on a 6-socket Gemini Bow base to target-craft Chaos DoT modifiers or inflictions like Withered and Poison.

 

Target Farming: How to Increase Your Chances

1. Atlas Passive Tree Investment

Allocate your Atlas Passive Points into the following nodes:

 

Chaos Monster Affix Chance (increases Chaos monsters in maps)

 

Additional Poison Chance on Enemies

 

Map Boss Drop More Unique Weapons

 

These passives amplify drop rates for ailment-themed gear like Plague Siege.

 

2. Scarabs and Sextants

Use Blighted Scarabs and Abyss Scarabs to spawn more poison/chaos enemies.

 

Use Sextants to roll map mods that increase monster life and rarity or add chaos effects.

 

3. Prophecies and Echoes of the Past

In POE 2, Echoes (the spiritual successor to Prophecies) sometimes grant enhanced drop modifiers in boss maps. If you receive an Echo hinting at “corruption, plague, or spreading rot,” it often means a chaos-themed encounter—and possibly a Plague Siege drop.

 

Crafting the Perfect Plague Siege Gemini Bow

If you can’t find a perfect Plague Siege bow, your next best option is crafting. Here’s how:

 

Step 1: Acquire a Gemini Bow Base

Drop or trade for a level 80+ Gemini Bow

 

Make sure it’s 6-linked and has a clean mod pool

 

Step 2: Use Fossil Crafting

Recommended Fossils:

 

Aberrant Fossil (more Chaos mods)

 

Corroded Fossil (more Poison/Wither mods)

 

Jagged Fossil (more Physical mods for base DPS)

 

Combine with a Prismatic or Sanctified Fossil for increased mod value

 

Use in a Prime Resonator (4-socket) for best results.

 

Step 3: Use Tempered Runes (POE 2 Exclusive)

In Path of Exile 2, Tempered Runes add a deterministic crafting layer. If you have a Tempered Rune of Chaos Amplification or Tempered Rune of Toxic Projection, you can attach it to the Gemini Bow before crafting to bias results toward Plague Siege-tier effects.

 

Can Plague Siege Be Obtained as a Unique?

Some players speculate that Plague Siege is a unique Gemini Bow introduced in the late beta or early access phase of POE 2. This hasn’t been confirmed officially, but data-mined leaks and early reports suggest it may eventually be accessible via:

 

Uber Labyrinth Enchant Rewards

 

Special League Mechanics like Sanctum or Ritual

 

Drop-only from the Poison-themed Uber Boss (Pathogen Queen)

 

Until this is confirmed, your best route is to craft or trade for a rare Gemini Bow with similar properties.

 

Trading for Plague Siege

On trade leagues, expect to pay the following:

 

Unrolled Gemini Bow Base (6-link): 30–50 Chaos Orbs

 

Crafted Plague Siege Lookalike (Chaos DoT): 3–10 Divine Orbs

 

Perfectly Rolled Plague Siege (if confirmed unique): 15–50 Divine Orbs depending on roll and league

 

Search for modifiers like:

 

+#% to Chaos Damage over Time Multiplier

 

+# to Level of Socketed Bow Gems

 

Adds #–# Chaos Damage to Attacks

 

#% chance to inflict Withered/Poison on Hit

 

Increased Projectile Speed or Damage over Time

 

Best Builds That Use Plague Siege Gemini Bow

Chaos Barrage Pathfinder

 

Focuses on fast attacks and stacking Poison through Barrage or Scourge Arrow.

 

Toxic Rain Deadeye

 

Uses overlapping pods and Plague Siege’s chaos scaling for big AoE DoT damage.

 

Puncture Bleed Champion

 

Uses physical base damage and bleed scaling, exploiting the high base of Gemini Bows.

 

Explosive Concoction Pathfinder

 

Combines flask synergy with chaos scaling and projectiles.

 

Conclusion

The Plague Siege Gemini Bow is one of the premier options for chaos- and poison-focused archers in Path of Exile 2. While it doesn’t drop early or easily, players who understand map targeting, fossil crafting, and rune modifiers can acquire or create one for powerful endgame builds. Whether you’re running Toxic Rain, Barrage, or Poison Puncture, the Plague Siege lives up to its name—spreading devastation with every shot.

 

For now, farming in high-tier Chaos-themed maps and using fossils or tempered runes are your best bets. But as POE 2 evolves, expect more deterministic sources cheap POE 2 Currency Orbs  and potential unique versions to emerge—so keep grinding and checking patch notes.
