Quick Answer: The Pit of Artificers is Diablo 4's primary glyph-leveling activity in Season 14. Each run costs 3 Runeshards, lasts up to 15 minutes (per Maxroll; Icy-Veins cites 10 minutes), and rewards 3–4 glyph upgrade attempts per clear. For the fastest glyph progression, run a Pit tier that is at least 10 above your current glyph rank (guarantees 100% upgrade success). Stygian Stones — the secondary reward from high-tier Pit bosses — are your ticket to Tormented Lair Boss carries and, in Season 15, the Horadric Cube Mythic upgrade loop.
The Pit of Artificers is the endgame's workhorse. Unlike Helltides or Nightmare Dungeons, it has one job and does it extremely well: level your Paragon Glyphs as fast as possible and occasionally drop a Stygian Stone that unlocks the Tormented Boss loop. If your glyphs are stuck at rank 40 while your build demands rank 90, every other improvement is wasted.
This guide covers how to unlock The Pit in Death Awakening (Season 14), the exact tier formula for efficient glyph leveling, Stygian Stone farming strategy, and a preview of what Patch 3.2.0 changes for The Pit when Season 15 launches.

How Do You Unlock The Pit in Season 14?
The Pit becomes available once you complete the Hellish Descent capstone dungeon (around character level 50 on the Seasonal realm). After clearing it, travel to Cerrigar in Scosglen and interact with the Artificer's Obelisk — the glowing stone structure northwest of the Cerrigar waypoint, the same spot used for The Tower. (Maxroll's Pit guide has the full map pin if you need it.)
Access cost: 3 Runeshards per run, consumed on entry with no refund on failure. Runeshards drop from Nightmare Dungeons, Helltide chests, Tree of Whispers caches, Legion Events, and World Bosses. They accumulate quickly once you hit Torment difficulty.
Tiers 1–10 are available from the start. Higher tiers unlock as you clear them — finishing with substantial time left on the clock unlocks additional tiers at once, so efficient early clears can skip you ahead faster. Efficient early-game Pit runs double as a fast tier-unlock path.
What Rewards Come From The Pit?
The Pit drops three categories of loot, ranked by practical value:
1. Glyph Upgrade Attempts (the entire reason to run The Pit) Each successful clear grants 3–4 upgrade attempts on any Paragon Glyph you choose (exact base count varies by source; deathless clears add one bonus attempt). This is non-negotiable for endgame progression — Nightmare Dungeons were the old glyph source, but as of Patch 3.1.0 (Season 14, per Blizzard's patch notes), The Pit is the exclusive glyph XP activity. Nightmare Dungeons no longer grant glyph upgrades.
2. Stygian Stones (from the final boss at higher tiers) These summoning materials drop from the Pit's randomly generated boss at elevated tiers. One Stygian Stone converts directly into any Greater Lair Key, which you then use to summon Tormented versions of Duriel, Andariel, and other Lair Bosses — the best Mythic Unique farm in the game. In Season 15, Stygian Stones feed the Resplendent Spark loop that powers Horadric Cube Mythic upgrades (more on this below).
3. Ancestral Legendary Gear (Item Power 925) Every run drops Ancestral Legendaries at Item Power 925 and Murmuring Obols. At high Pit tiers, gear rolls with Greater Affixes (50% stronger stat rolls, marked with a gold star). These aren't the main reason to farm The Pit, but they contribute to your gear baseline.
Community confirmed via r/diablo4: "The Pit is the only efficient way to push glyphs past rank 50. You need Legendary glyphs for any serious endgame build — the Pit is the answer." — u/D4SpeedRunner_Keva (Thread: "Season 14 glyph guide, Pit is mandatory", 2026-07)
One important correction for returning players: The Pit does not drop masterworking materials. That changed in Patch 3.1.0. Obducite (the core masterworking material) now comes exclusively from Nightmare Dungeons, Infernal Hordes, Kurast Undercity (Tribute of Refinement), and mercenary bartering — confirmed by Maxroll's masterworking guide. Pre-Season 14 guides citing "Obducite from Pit Tier 1–29" are outdated and incorrect.
What Pit Tier Should You Run for Glyph Leveling?
The upgrade success rate scales with how much your chosen Pit tier exceeds your glyph's current rank. Two thresholds matter:
| Glyph Rank | Minimum Pit Tier (100% success) | Optimal Pit Tier (bonus levels) |
|---|---|---|
| Rank 10 | Pit 20 | Pit 30 |
| Rank 20 | Pit 30 | Pit 40 |
| Rank 30 | Pit 40 | Pit 50 |
| Rank 40 | Pit 50 | Pit 60 |
| Rank 50 | Pit 60 | Pit 70 |
| Rank 75 | Pit 85 | Pit 95 |
| Rank 100 | Pit 110 | Pit 120 |
| Rank 125 | Pit 135 | Pit 145 |
| Rank 150 (cap) | N/A | N/A |
The rule: run Pit tiers at Glyph Rank + 10 for guaranteed success on every attempt. At Glyph Rank + 20, each attempt grants an extra glyph level — more than doubling your progression speed per run. Push as high as you can clear comfortably within the time limit and with at most one death.
The milestone that matters most: Rank 51. When a Rare glyph hits Rank 51, it upgrades to Legendary — gaining an expanded influence radius and a powerful Legendary bonus effect. The upgrade costs 15,000 gem fragments at Rank 50 (per Maxroll's glyph data). Legendary glyphs are required for any serious endgame build and represent the biggest single power jump in Paragon progression. Every Pit session should be evaluated against "am I on track to hit Rank 51 on each of my priority glyphs?"
Glyphs cap at Rank 150. The 150-tier Pit ladder exists precisely to give maxed-out players a meaningful challenge ceiling.
How Does The Pit's Death Timer Work?
The run timer (up to 15 minutes per Maxroll) is strict, and deaths eat into it directly:
- 1st death: −30 seconds
- 2nd death: −60 seconds
- 3rd death and beyond: −90 seconds each
(Per The Gamer's Pit rewards guide; Maxroll's guide doesn't document the exact deduction values.)
A three-death run costs 180 seconds — 3 minutes gone, which can turn a clean clear into a failed run on tight tiers. The deathless bonus glyph attempt (your 4th) is also lost on any death, making survival worth roughly one-quarter of your total glyph investment per run.
Strategy: prioritize survivability over raw damage on your current push tier. Dropping to a tier you can consistently clear deathless is usually faster overall than struggling through a tier that kills you twice per attempt.

Stygian Stones: Farming the Tormented Boss Loop
Stygian Stones are the Pit's most strategically valuable secondary drop. Each Stygian Stone converts 1:1 into any Greater Lair Key, which summons Tormented versions of Lair Bosses — and Tormented bosses are the only reliable source of Resplendent Sparks (first Tormented kill each guarantees a Spark).
The full loop:
Farm Pit (higher tiers) → collect Stygian Stones → convert to Greater Lair Keys → kill Tormented Duriel / Andariel / Harbinger of Hatred → earn Resplendent Sparks + Mythic Unique rolls
Tormented bosses carry significantly better Mythic Unique drop rates than standard Lair Bosses. The complete Season 14 endgame revolves around stacking enough Stygian Stones to sustain a rotation of Tormented kills.
For the most efficient Stygian Stone drops, aim for higher Pit tiers — community reports on r/diablo4 consistently find Stygian Stones becoming reliable around T80+ at higher Torment levels. Below T50, drops are rare enough that the Tormented Boss loop becomes difficult to sustain.
What Changes for The Pit in Season 15 (Patch 3.2.0 Preview)?
The 3.2.0 PTR (August 4–11, 2026) confirmed no mechanical changes to The Pit itself — the run timer, Runeshard cost, glyph attempt system, and tier structure all carry over unchanged. The Pit in Season 15 operates identically to Season 14.
What changes is the value of what you farm there, through the Season 15 Horadric Cube overhaul.
In Season 15, Resplendent Sparks — which you earn from Tormented Lair Boss first kills — become the primary Mythic crafting currency. The Horadric Cube in Season 15 gains a direct Unique-to-Mythic upgrade path, preserving all existing stats, tempering, and masterworking on an item and converting it to Mythic quality. The cost was 5 Resplendent Sparks per item in PTR testing (provisional — may change before launch).
This makes the Stygian Stone loop from Pit farming the foundation of the S15 Mythic chase:
Farm Pit → Stygian Stones → Tormented Boss kills → Resplendent Sparks → Horadric Cube Mythic upgrades
If you start farming Stygian Stones now in S14, you're building the exact muscle memory and gearing baseline for the Season 15 Mythic loop.
Season 15 also introduces Challenge Dungeons as a separate endgame activity — but Blizzard confirmed these are not a Pit replacement. Challenge Dungeons cannot activate during a Pit run and serve as a parallel endgame pillar, not a successor.
Full Season 15 details will be revealed at BlizzCon 2026 (September 12–13). The expected Season 15 launch is around September 15, 2026, aligned with the in-client Season 14 end timer.
For the Horadric Cube crafting loop in detail, see the Diablo 4 Horadric Cube Season 15 crafting guide, the Season 15 Day 1 checklist for how to set yourself up for launch day, and the Iconic Mythics Season 15 farm guide for which Mythic Uniques to target once your Stygian Stone loop is running.
Pit Strategy: Practical Tips for Faster Runs
Kill speed beats tankiness (mostly). The run timer punishes slow clearing. Build for AoE damage and movement speed over raw survivability — unless you're dying repeatedly, in which case one tier lower with deathless clears is faster.
Skip elite packs when behind on time. Boss encounter is required; everything else is optional. When the timer drops below 4 minutes and the boss isn't dead, skip whatever non-essential packs remain and go straight to the boss room.
Rotate glyphs strategically. You earn 3–4 upgrade attempts per run and you choose which glyph to upgrade. Prioritize glyphs furthest from Rank 51 first until they all hit Legendary, then shift to pushing all of them toward Rank 100 together. Don't dump 30 attempts into a single glyph while others sit at Rank 12.
Track your Stygian Stone pace. Aim for the conversion rate needed to run Tormented Bosses at whatever frequency your build requires. If you need 5+ Greater Lair Keys per week for Mythic farming, that's the Stygian Stone target driving your Pit session count.
Team vs. solo: The Pit scales for group play. Group clears are faster but you share glyph upgrade opportunities — each player still gets their own attempt pool, but coordination matters on which glyphs each person targets.

FAQ
What is The Pit of Artificers in Diablo 4? The Pit of Artificers is a tiered endgame activity in Diablo 4 accessed through the Artificer's Obelisk in Cerrigar, Scosglen. It offers 150 difficulty tiers, costs 3 Runeshards per run, and is the game's exclusive source of Paragon Glyph upgrade attempts in Season 14.
How many Runeshards does The Pit cost? Each Pit run costs 3 Runeshards, consumed on entry. Runeshards are not refunded if you fail the run. They drop from Nightmare Dungeons, Helltide chests, Tree of Whispers caches, Legion Events, and World Bosses.
Does The Pit drop masterworking materials in Season 14? No. As of Patch 3.1.0, The Pit no longer drops Obducite, Ingolith, or Neathiron. Masterworking materials in Season 14 come from Nightmare Dungeons, Infernal Hordes, Kurast Undercity (Tribute of Refinement), and mercenary bartering. Pre-Season 14 guides claiming Pit drops masterworking materials are outdated.
How do you get Stygian Stones from The Pit? Stygian Stones drop from the final boss of a Pit run at higher tiers (community evidence points to consistent drops in the T80–T120+ range at Torment VI). Each Stygian Stone converts 1:1 into any Greater Lair Key, used to summon Tormented Lair Bosses.
What Pit tier should I run to level glyphs fastest? Run a Pit tier equal to your glyph's current rank plus 10 for 100% upgrade success on every attempt. Running at rank + 20 grants bonus glyph levels per attempt for faster progression. The most important milestone is reaching Rank 51, which upgrades a Rare glyph to Legendary for 15,000 gem fragments.
Is The Pit changing in Season 15? The Pit's core mechanics — run timer, 3 Runeshards per run, 3–4 glyph attempts per clear, tiers 1–150 — are confirmed unchanged in the Patch 3.2.0 PTR (which ran August 4–11, 2026). What changes is the value of Stygian Stones: in Season 15, they feed the Horadric Cube Resplendent Spark loop, making Pit farming the foundation of the Mythic upgrade system.
