An Abyss crack in your map looks like a minor event — a fissure in the ground that floods out a few monsters. What it can unlock is something else. A single Lichborn Rogue Exile inside Abyssal Depths can drop a Heart of the Well Diamond worth hundreds of Divines when it rolls two Tier A mods on the same jewel.
This guide covers the Abyss system as of patch 0.5.2 (June 12, 2026) — from the three-stage surface mechanic to Depths spawning conditions, with a build-archetype mod priority table and an Abyssal Eye socketable guide that no other current resource provides. Whether you are running a casual throughput strategy or the high-end Amanamu Void omen play, the decision framework here tells you exactly where your time goes.
Quick Start Checklist
- Allocate Lightless Legions in your Atlas tree first — it raises the Abyssal Depths spawn chance by 50%.
- Allocate Shadow of Undeath so Rogue Exiles near Abyss pits become Lichborn (the only source of Heart of the Well Diamonds).
- Buy Abyss Tablets in 10-use versions — guaranteed Abyss events per map at the best cost-per-encounter ratio.
- Enter every Abyssal Depths that opens and kill all Lichborn exiles before leaving.
- Reveal Desecrated Modifiers at the Well of Souls — use the build-archetype table below before selecting which mods to keep.
How the Abyss Works: Three Stages
Walking over an Abyss crack triggers a chained event. A fissure tears open and monsters pour out — the fissure seals once you kill everything that emerged. Work through every fissure in the chain and the pit opens. The pit spawns a heavier wave, and which monster types you killed to seal the fissures influences what spawns from it: kill Rogue Exiles near the fissure and the pit produces Lichborn — enhanced exiles carrying Abyssal Modifiers that can drop the Heart of the Well Diamond.
When the final pit monster dies, one of two things happens:
- Abyssal Trove: The pit seals and a chest rises. You collect Ancient Jawbones, raw currency, and occasionally rare gear. Fast and guaranteed.
- Abyssal Depths: Instead of a Trove, the pit opens into a separate dungeon. Not guaranteed without Atlas investment, but significantly more rewarding.
Patch 0.5.2 tuned down the damage on the most dangerous Abyss elites — the 0.5.2 patch notes reduced the Blackblooded Elite’s channeled cold beam, the Lightless Vengewing’s fire beam, the Lightless Moray’s flamethrower, and the Strider of the Pit’s Lightning Strike. Depths are safer to run now than they were at 0.5.0 launch.
Verified on patch 0.5.2 (June 12, 2026). GGG may adjust values with future updates.
Abyssal Depths vs Trove: When Each Wins
Depths almost always generate more raw value per event, but they come with a hard penalty: die inside and you cannot re-enter. That makes your build’s survivability a real input into the decision.
| Your Goal | Enter Depths? | Reason |
|---|---|---|
| Farm Heart of the Well | Yes — always | Lichborn only spawn inside Depths |
| Collect Abyssal Eye socketables | Yes — always | Ulaman’s/Kurgal’s/Amanamu’s Gaze drop only in Depths |
| Unlock Kulemak fight | Yes — always | Faction statues for Kulemak’s Final Form are only inside Depths |
| Bulk Ancient Jawbone crafting | No — skip Depths | Surface Troves deliver Jawbones faster without death risk |
| Amanamu’s Void omen farming | No — skip Depths | The Void modifier trick works on surface rares, not inside Depths |
| Build is squishy / under-geared | No — skip Depths | Death inside ends the run entirely; Troves still pay |
In tier 79+ maps, a sealed pit can instead open into a Lightless Void or Dark Domain — rarer variants that pack even more Rare monsters with Abyssal Modifiers. Enter these unconditionally regardless of your farming goal.
The practical decision rule: if you are running the Atlas for jewel hunting, enter every Depths. If your session is about currency and crafting supplies, farm surface events at higher density and skip the Depths gamble.
Heart of the Well Diamond: Mod Priority by Build Archetype
The Heart of the Well Diamond drops from Lichborn Rogue Exiles at item level 48 or higher. It drops with four hidden Desecrated Modifiers — take it to the Well of Souls to reveal them. Each reveal presents three choices; you pick one and it locks permanently. You can reroll each slot up to twice using Omen of Abyssal Echoes (one omen per slot, four omens total to reroll all four).
The community-verified modifier tier list from the 0.5.2 meta breaks down like this:
- Tier A — take every time: % Damage as Extra Lightning, Chaos, Fire, or Cold Damage; % Increased Critical Hit Chance; % Increased Critical Hit Chance for Spells; % Increased Critical Damage Bonus; % Increased Critical Spell Damage Bonus
- Tier B — solid utility: % Movement Speed; % Armour/Energy Shield/Evasion from Body Armour; % Skill Speed; % Reduced Slowing Potency of Debuffs
- Tier C — situational: % Attack Speed; % Cast Speed; % Cooldown Recovery Rate; % Exposure Effect; Rage when Hit; % Mana Cost Efficiency
One hard rule: Instant Leech no longer rolls as of patch 0.5.0. Any Heart of the Well you see with it predates that change.
The tier list tells you what is objectively strong, but it doesn’t tell you which mods are worth your Omen of Abyssal Echoes for your build. That is the table competitors don’t provide:
| Build Type | Priority 1 | Priority 2 | Priority 3 | Avoid or Reroll |
|---|---|---|---|---|
| Elemental Caster (Stormweaver, Infernalist, Chronomancer) | % Crit Hit Chance for Spells | % Crit Spell Damage Bonus | % Dmg as Extra (match your element) | Attack Speed, Rage when Hit |
| Physical / Attack (Warrior, Martial Artist, Warbringer) | % Crit Hit Chance | % Crit Damage Bonus | % Dmg as Extra Fire or Lightning | Spell Crit mods (do not scale attacks) |
| Bow / Ranged Attack (Deadeye, Pathfinder, Ranger) | % Crit Hit Chance | % Crit Damage Bonus | % Dmg as Extra Cold or Lightning | Spell Crit mods, Cooldown Recovery Rate |
| Minion Summoner (Lich, Spirit Walker, Invoker) | % Skill Speed | % Movement Speed | % Armour / Energy Shield / Evasion | Crit Hit Chance and Crit Damage Bonus (do not scale minion damage in 0.5.2) |
| DoT / Ailment | % Dmg as Extra Chaos (scales DoT conversion) | % Skill Speed | % Movement Speed | Crit Damage Bonus (most DoT builds do not crit-dip) |
The high-value outcome for attack and caster builds is landing two Tier A crit mods alongside a matching elemental conversion — that combination produces a jewel that outperforms nearly every rare alternative and routinely sells for significant currency on the player market. Minion builds are the exception: their Tier A priority is defensive utility because crit mods do not propagate to minion damage in the current patch.
Abyssal Eye Socketables: Which Gaze for Your Build
Three unique Abyssal Eye items drop from Abyssal Liches inside Depths. Each belongs to a different Eye type, slots into gear or jewel sockets, and scales its effect based on how many jewels of the same Eye type you have socketed anywhere on your character. You can equip only one of each type simultaneously.
| Item | Eye Type | Effect | Best For |
|---|---|---|---|
| Ulaman’s Gaze | Searching Eye | +10–20 Dex; projectiles gain 4% Chain chance per Searching Eye socketed, up to 20% | Bow and ranged builds (Deadeye, Pathfinder, Ranger) |
| Kurgal’s Gaze | Hypnotic Eye | +10–20 Int; +8% increased Effect of Arcane Surge per Hypnotic Eye socketed, up to 40% | Spell casters (Stormweaver, Chronomancer, Infernalist hybrid) |
| Amanamu’s Gaze | Ghastly Eye | +5–10 All Attributes; Minions gain +6% Damage over Time Multiplier per Ghastly Eye socketed, up to +30% | Minion summoners (Lich, Spirit Walker, Invoker) |
The chain scaling on Ulaman’s Gaze is not just a quality-of-life bonus — it materially changes how bow builds clear indoor maps. At two Searching Eye jewels plus the Gaze, you reach 12% chain chance on every projectile, which means arrows regularly bounce through tight corridor packs. At five Searching Eyes, you hit the 20% cap.
For melee attack builds in patch 0.5.2, none of the three Gaze items has a direct attack-scaling bonus. Most Warriors and Martial Artists skip Gaze items until they have comfortable item slots, or use Kurgal’s Gaze if their build includes any triggered spell components. If you are unsure, prioritize a strong rare jewel in the slot over a Gaze that does not directly scale your primary damage type.
Atlas Passive Setup and the Two Farming Routes
Abyss farming scales directly with your Atlas investment. The correct passive order matters because Lightless Legions enables the Depths — without it, the entire jewel-hunting strategy depends on random luck.
Priority passive order:
- Lightless Legions — 50% increased chance for Depths or Lightless Void instead of a surface Trove. Take this first, always.
- Shadow of Undeath — 50% chance for Rogue Exiles near Abyss events to become Lichborn. Required for Heart of the Well farming.
- Dark Bloodlines + Unholy Influence — raise monster quantity and rarity in Abyss events.
- Sprawling Rupture — more fissures per Abyss event, which means more monsters and more Lichborn opportunities.
For tablets: always buy 10-use Abyss Tablets. Bonus Abyss versions cost roughly 30–50 Exalted Orbs and force an additional Abyss encounter with improved loot outcomes — the cost per event is far lower than single-use tablets. See our endgame mapping guide for full tablet budgeting context.
Route 1 — Throughput (any build, entry-level investment):
Seal every pit, collect every Trove, enter Depths whenever they open. With Shadow of Undeath active, Lichborn spawn regularly and each one is a Heart of the Well roll. Currency, Ancient Jawbones, and raw gear accumulate fast. No special execution required — this is the baseline Abyss farming loop.
Route 2 — Amanamu’s Void Trick (high-end omen farming):
With Lightless Legions allocated, Amanamu-loyal rare monsters appear with a darkness cloud (Amanamu’s Void modifier). Kill the rare while it stands inside its cloud and it drops Omen of the Liege. Lure the same rare outside the cloud before killing it, and it can instead drop Omen of Light or Omen of Abyssal Echoes — the omens that sell for significant currency in the player market. The mechanic requires identifying the modifier quickly and repositioning, but at full Atlas investment it outpays Route 1 per hour for experienced players. Check our currency farming guide for context on where Abyss ranks against other endgame strategies.
Player-Type Breakdown
| Player Type | Focus On | Skip or Defer |
|---|---|---|
| New Player / Fresh League Start | Run Abyss events for Ancient Jawbones to fund early crafting. Skip Depths until your build can safely clear them. | Amanamu Void trick, tablet investment, Gaze farming |
| Casual Farmer | Allocate Lightless Legions and Shadow of Undeath. Enter Depths opportunistically, sell Hearts of the Well you find. | Omen targeting (complex execution), full tablet strategy |
| Hardcore Optimizer | Full Atlas Abyss setup (all four priority passives). Run Route 2 for omen farming. Craft Hearts with Omen of Abyssal Echoes to hit double Tier A mods for your archetype. | Nothing in this guide — you want the full stack |
| Completionist | Farm all three Lich types to collect Ulaman’s, Kurgal’s, and Amanamu’s Gaze. Each requires encountering the specific Lich inside Depths via faction statue interactions. | Route 2 omen farming until all three Gazes are collected |

FAQ
How often do Abyssal Depths spawn without Atlas investment?
Uncommon — it is a probabilistic outcome when a pit seals. Allocating Lightless Legions raises the rate by 50%, and 10-use Abyss Tablets guarantee the Abyss event appears on the map in the first place, which also improves Depths frequency.
Can I farm Heart of the Well without entering Depths?
No. Lichborn Rogue Exiles — the only confirmed source — spawn exclusively inside Abyssal Depths. There is no surface drop path for Heart of the Well in 0.5.2.
What Abyssal Eye socketable should I get first?
Match it to your primary damage type: Kurgal’s Gaze for casters (Arcane Surge scaling to 40%), Ulaman’s Gaze for bow and ranged builds (up to 20% projectile chain chance), Amanamu’s Gaze for minion summoners (up to +30% DoT Multiplier for minions). If you are a melee attack build without a spell component, prioritise a strong rare jewel over any Gaze item in 0.5.2.
What do I do with a bad Desecrated Modifier on my Heart of the Well?
Use Omen of Abyssal Echoes to reroll that specific slot — you get two rerolls per modifier slot. If three attempts all miss Tier A for your archetype, either accept a Tier B utility mod (Movement Speed and Skill Speed are genuinely useful) or use Omen of Light to annul only the Desecrated Modifier and start that slot over from scratch.
