What Is the Abyss in Path of Exile 2?

Abyss is a special encounter that appears in both the campaign and the endgame. You follow a crack in the ground—called a fissure—as it moves across the zone, spawning waves of Abyss monsters. Close enough fissures, and a pit opens, releasing stronger enemies. Clearing the pit rewards you with an Abyssal Trove, or sometimes an entrance to the Abyssal Depths.

Abyss is introduced early in Act 2, so new characters can engage with it right away.

How Does the Abyss League Work in PoE 2?

Once you find an Abyss fissure, killing monsters nearby causes it to seal and spawn waves of new enemies. Multiple fissures can appear in one area, and more pits will open as you progress into later acts and endgame maps.

Abyss is not a separate league—it's fully integrated into the core game.

How Abyss Works in PoE 2: Fissures, Depths, Troves & Bosses

Abyss in PoE 2: Best Rewards, Mechanics, Tips & Map Bosses

Where Can You Encounter Abyss Fissures?

  • First appearance: Clearfell in Act 2.
  • After that: randomly throughout campaign zones and all map tiers.

Some map modifiers increase the number of pits or force Abyss Depths or Abyssal Bosses to appear.

Is Abyss Part of the Endgame or Campaign?

Both. Abyss can spawn in acts starting from Act 2, and it continues into the endgame maps. There is even an Atlas Passive Tree dedicated to Abyss content, allowing you to specialize your farming.

Mechanics & Gameplay

How Do Abyss Fissures Spawn and What Triggers Them?

They appear near monster packs. When you kill monsters close to the fissure, it seals and releases Abyss monsters. Seal enough fissures → a pit opens.

What Are Abyssal Depths? How Are They Different?

Abyssal Depths is a full underground zone accessible when a pit transforms into a Depths entrance. Inside, you'll face:

  • Stronger rare monsters (always have Abyssal modifiers)
  • Rows of Abyssal Troves
  • A Large Abyssal Trove with exclusive Abyss rewards

In area level 79+ maps, Depths may instead become:

  • Lightless Void
  • Dark Domain
    …each containing an Abyssal Commander boss.

What Rewards Come From Abyss Encounters?

Abyss rewards scale with difficulty. You can get:

  • Random loot (weapons, armor, PoE 2 Currency)
  • Abyss-exclusive preserved bones
  • Abyssal Trove variants like Armoury, Arsenal, Coffer

Depths also drop:

  • Abyss-exclusive lineage support gems
  • Unique Abyssal Eyes

How Do Abyss Monster Modifiers Work?

Abyss monsters can absorb modifiers from other monsters killed nearby. Some modifiers transform into Abyssal modifiers, giving enemies new mechanics like:

  • Exploding revenants
  • Volatile orbs
  • Teleport + desecration clouds
  • Invulnerability waves

Abyss fights get harder the more chaos you drag into them.

What Are Abyssal Troves? What Can Drop?

Troves are chests rewarded for clearing pits. They can drop:

  • Gear
  • Currency
  • Preserved bones
  • Trove-type-specific loot (e.g., weapons only, armor only)

Sometimes a pit skips the Trove and opens Depths instead.

What Are Desecrated Modifiers and How Do They Affect Crafting?

Desecrated modifiers are special item mods hidden behind Abyssal glyphs. Take these items to the Well of Souls to reveal your choice of one of three modifiers. Some are mods that normally cannot roll on items.

This makes Abyss one of the most interesting crafting systems in PoE 2.

How Do Abyss-Related Omens and Bones Work?

Abyss monsters can drop Abyss Omens. Troves drop preserved bones, the main currency for interacting with Abyss crafting.

How Does Abyss Interact With Other League Mechanics?

Abyss links surprisingly well with other encounters:

  • Kill a map boss near a pit → a huge larvae boss spawns.
  • Kill a Rogue Exile near a pit → it respawns as a Lichborn version with elevated loot.
  • Essence monsters near pits can give a special Essence of the Abyss.
  • Expedition bombs near an Abyss will also summon Abyss monsters.

These synergies can explode your loot output if timed well.

Maps & Bosses

Is There an Abyss Atlas Map?

Yes—Abyss appears in maps naturally and has special Atlas passives that improve:

  • Spawn rates
  • Depths entrances
  • Abyssal Trove rarity
  • Boss encounters
    (As described in the attached material.)

What Enemies and Bosses Appear in Abyss Maps?

Abyss zones contain a wide roster of monsters such as:

  • Blackblooded elites
  • Lightless serpents
  • Giant larvae
  • Striders of the Pit

In high-level maps, Depths can reveal the Abyssal Commanders:

  • Tasgul, Swallower of Light
  • Vandroth, Blackblooded Enslaver

Defeating them drops Kulemak's Invitation, used to fight the Vessel of Kulemak.

Rewards & Items

What Unique Items Drop From Abyss?

Large Abyssal Troves and Depths can drop:

  • Unique Abyssal Eyes
  • Unique lineage supports

Are There Exclusive Abyss Crafting Materials?

Yes—preserved bones fuel the Abyss crafting system.

Is Abyss Loot Worth Farming?

If you enjoy crafting or chasing unique gems, Abyss is very rewarding. Troves and Depths provide consistent loot, and Abyssal map modifiers can supercharge drops even further.

Tips & Strategies

Best Strategies for Closing Fissures

  • Stay close—distance slows fissure progression.
  • Move fast between fissures to avoid monster buildup.
  • Use strong AoE to clear waves quickly.

How Dangerous Are Abyss Monsters?

Abyss monsters hit hard because of absorbed modifiers. Expect:

  • Volatile explosions
  • High DoT zones
  • Teleport slams
  • Unstable revenants chasing you

Bring movement skills and defensive layers.

Tips for Beginners

  • Don't stand still—the fissures often spawn mobs behind you.
  • Clear trash quickly so pits absorb fewer dangerous mods.
  • In Depths, pace yourself—rare monsters always have Abyssal modifiers.

Are All Builds Viable?

Most builds can handle early Abyss, but high-end Abyss requires:

  • Good AoE
  • Reliable mobility
  • Some form of mitigation or DoT resistance

Weak single-target builds may struggle with swarms.

Optimizing Abyss Crafting

  • Reveal desecrated mods only when you have multiple items to compare.
  • Save high-tier bones for items that actually need powerful mods.
  • Some unrevealed mods can roll unusually rare effects—keep an eye out.

Community & Balance Questions

Are There Known Annoying Abyss Behaviors?

Common player gripes include:

  • Monsters spawning behind obstacles
  • Volatile orbs being hard to see
  • Depths sometimes feeling overtuned

But overall, Abyss is viewed as one of the more rewarding mechanics.

Is Abyss Worth Engaging With?

Absolutely—between loot, crafting, bosses, and synergy with other mechanics, it's one of the most efficient “value per time spent” systems in PoE2.

Should You Start a New Character for Abyss League?

Since Abyss is core, both Standard and new characters can enjoy it. Starting fresh, however, lets you experience Abyss scaling from Act 2 onward.

Summary

Abyss in PoE 2 is a fast-paced, high-reward mechanic that mixes swarm clearing, explosive modifiers, and deep crafting systems. You can encounter fissures in Act 2 onward, dive into Abyssal Depths, fight Abyssal Commanders, earn special Troves, and even improve items with unique desecrated modifiers. The system interacts with many other mechanics and offers strong loot for the time invested. Whether you enjoy crafting, farming, or bossing, Abyss has something to offer.
