The Pit of Artificers is Diablo 4’s most important endgame activity for pushing power. It serves as the primary source for upgrading your Paragon Glyphs, and mastering it separates casual players from those tearing through the upper Torment tiers. Whether you just hit the endgame or you are deep into optimizing a build, understanding how the Pit works gives you a clear path forward in Season 13: Lord of Hatred.
What Is the Pit of Artificers in Diablo 4?
The Pit of Artificers is a tier-based endgame dungeon introduced in Diablo 4’s 1.4.0 update for Season 4. Think of it as Diablo 4’s version of Greater Rifts from Diablo 3. You load into a randomized dungeon, race against a 15-minute timer to kill enough monsters, then defeat a boss before the clock hits zero.
The Pit scales all the way to Tier 150, and each tier increases enemy health and damage output. It is designed to push your build to its absolute limit.
How to Unlock the Pit of Artificers
Unlocking the Pit of Artificers depends on which realm you are playing on:
- Seasonal Realm: Complete the Capstone Dungeon called Hellish Descent, which unlocks at Rank II of the Season Rank track.
- Eternal Realm: Reach character level 70.
Once unlocked, head to Cerrigar in Scosglen or Temis and interact with the obelisk to enter. Your Pit progression is shared across all characters on the same realm, so you do not start from scratch when you swap to an alt.
Pit Tier System and How Tier Progression Works
The Pit of Artificers features 150 total difficulty tiers. You start at Tier 1 and unlock higher tiers by clearing runs before the timer expires. How much time you have left after defeating the boss determines how many tiers unlock above your current level:
| Time Remaining After Boss Kill | Tiers Unlocked |
|---|---|
| Under 4 minutes | 1 next tier |
| 4 to 6 minutes | 3 additional tiers |
| 6 or more minutes | 5 additional tiers |
For example, clearing Tier 1 with 6+ minutes left unlocks up to Tier 6 directly. Speed matters here, and that means bringing a fully optimized endgame build rather than something cobbled together from leveling gear
If the timer expires before you defeat the boss, you can still finish the run for basic loot. However, you will not receive Masterworking materials or unlock the next tier.
Pit Tiers and Torment Difficulty Unlocks
Completing higher Pit tiers also unlocks Torment difficulty levels for the rest of the game. You need to reach Tier 10 to unlock Torment 1. From there, each subsequent Torment tier unlocks every five Artificer tiers above that.
This makes the Pit your primary path to accessing harder Torment difficulties, not just a source of Glyph upgrades. Prioritize pushing Pit tiers if you are trying to progress into higher Torment content.
Pit Layout and Dungeon Structure
Each Pit run consists of five floors connected by portals. The layout of every floor and the monsters on it are randomized each time. You need to slay enough enemies to fill a progression bar before a portal opens to the boss arena.
Elite monsters contribute the most progression, so prioritize hunting them down. As you move through each floor, kill small enemies along the way to avoid backtracking. Artillery and Blast Wave shrines do not spawn inside the Pit, so you cannot rely on shrine buffs to carry you through tough rooms.
Pit Rewards: Glyphs, Loot, and Masterworking
Completing a Pit run rewards:
- Ancestral Legendary items
- Murmuring Obols
- Paragon Glyph upgrade attempts
Glyph upgrades are the main reason to run the Pit repeatedly. After defeating the boss before the timer expires, you receive upgrade attempts based on the following:
- Base: 4 attempts
- No Death Bonus: 1 extra attempt
- War Plans Nodes: Up to 4 additional attempts
The success rate of each attempt scales with the difference between your Glyph’s current rank and the Pit tier you completed. If the tier you cleared is more than 20 levels above your Glyph’s rank, the upgrade is guaranteed. Completing tiers significantly higher than a Glyph’s rank can also grant bonus upgrade ranks per attempt, letting you level low-rank Glyphs extremely fast.
Glyphs cap at level 150. They gain radius increases at ranks 25 and 50, and unlock a Legendary affix at rank 51 that adds a new passive effect. Glyphs you have not found elsewhere can also drop at the end of a successful Pit run.
Failing to beat the timer locks you out of Masterworking materials for that run, which ties directly into your gear progression.
The Artificer’s Tower Leaderboard
Once the Artificer’s Tower unlocks, you can compete with other players to see who can clear Pit of the Artificer runs most quickly. You earn rewards based on your performance, so it is worth attempting if you want extra account-wide rewards on top of your normal Pit farming.
The Pit Boss Fight
Every Pit run ends with a randomized boss pulled from the same pool used in The Tower. The boss spawns after you fill the progression bar, and you need to defeat it before the 15-minute timer runs out.
Boss health pools and mechanics vary significantly between encounters. Some bosses die fast and have straightforward patterns. Others have large health pools or mechanics that eat clock time. As you farm the Pit repeatedly, you will learn which bosses suit your build and which ones slow you down.
Shadow bosses deal damage throughout the fight. They apply a debuff that stacks up to three times. At three stacks, the boss deals considerably more damage. Avoid the mechanics where possible to keep the stacks low and maintain your pace.
If you want a clean kill, learn each boss’s abilities and dodge the dangerous hits rather than tanking through them.
Pit Strategy and Tips for Faster Clears
Getting faster Pit clears comes down to three things: build optimization, efficient pathing, and boss execution.
Build Optimization
The Pit is a timed challenge. A durable tank build that cannot kill enemies quickly enough will fail just as easily as a fragile glass cannon build. You need both damage output and enough survivability to survive boss mechanics. Make sure you Temper and Masterwork all your gear at the Blacksmith and socket your best Gems before entering.
The Paladin and Warlock both have strong Pit builds in Season 13, and checking the current class tier list helps you pick the right class for the content.
Pathing and Progression
Elites give the most progression toward summoning the boss. Move through floors with purpose, kill elites first, and clean up small enemies as you travel rather than looping back. Efficient routing through the five floors saves time that becomes critical at higher tiers.
Tier Selection
You do not always need to push your absolute hardest tier. Running tiers 10 to 20 levels above a Glyph’s rank lets you blast through runs quickly while still getting bonus upgrade ranks. Save the high push tiers for Glyphs that already sit at a high rank and need the bigger level gap to score a guaranteed upgrade.
Knowing When to Reset
If a run goes badly early, such as a bad floor layout, a slow elite spawn, or a rough boss matchup, you do not have to finish it. Teleport back to town, return to the Pit entrance in Cerrigar or Temis, and start a new run. Starting a new run closes the previous portal automatically. Play Now!
