Continue ShoppingAbyss 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.
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.

Some map modifiers increase the number of pits or force Abyss Depths or Abyssal Bosses to appear.
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.
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.
Abyssal Depths is a full underground zone accessible when a pit transforms into a Depths entrance. Inside, you'll face:
In area level 79+ maps, Depths may instead become:
Abyss rewards scale with difficulty. You can get:
Depths also drop:
Abyss monsters can absorb modifiers from other monsters killed nearby. Some modifiers transform into Abyssal modifiers, giving enemies new mechanics like:
Abyss fights get harder the more chaos you drag into them.
Troves are chests rewarded for clearing pits. They can drop:
Sometimes a pit skips the Trove and opens Depths instead.
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.
Abyss monsters can drop Abyss Omens. Troves drop preserved bones, the main currency for interacting with Abyss crafting.
Abyss links surprisingly well with other encounters:
These synergies can explode your loot output if timed well.
Yes—Abyss appears in maps naturally and has special Atlas passives that improve:
Abyss zones contain a wide roster of monsters such as:
In high-level maps, Depths can reveal the Abyssal Commanders:
Defeating them drops Kulemak's Invitation, used to fight the Vessel of Kulemak.
Large Abyssal Troves and Depths can drop:
Yes—preserved bones fuel the Abyss crafting system.
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.
Abyss monsters hit hard because of absorbed modifiers. Expect:
Bring movement skills and defensive layers.
Most builds can handle early Abyss, but high-end Abyss requires:
Weak single-target builds may struggle with swarms.
Common player gripes include:
But overall, Abyss is viewed as one of the more rewarding mechanics.
Absolutely—between loot, crafting, bosses, and synergy with other mechanics, it's one of the most efficient “value per time spent” systems in PoE2.
Since Abyss is core, both Standard and new characters can enjoy it. Starting fresh, however, lets you experience Abyss scaling from Act 2 onward.
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.
