Diablo 4 Season 3: Season of the Construct Guide

Key Takeaways

Season of the Construct launched January 23, 2024, sending players into underground Vaults beneath Kehjistan to stop the demon Malphas from weaponising Zoltun Kulle's ancient Loom.
The Seneschal Companion, a customisable mechanical construct, slotted up to 2 Governing Stones (attacks) and 6 Tuning Stones (utility), drawn from a pool of 12 Governing and 27 standard Tuning Stones.
Vaults replaced standard dungeons as the season's primary content loop: enter with Pearls of Warding, preserve Zoltun's Warding through elemental Hazards, and open a Wardwoven Chest at the boss.
The Gauntlet — a weekly fixed leaderboard dungeon — debuted mid-season; top performers earned a permanent record in the Hall of the Ancients.
Helltides ran near-continuously in Season 3, farming Aberrant Cinders replacing the Season 1 restricted windows.
PC players gained optional W-A-S-D keyboard movement as an alternative to mouse navigation.

Each of those points is covered in detail below.

Unearthing Zoltun Kulle's Legacy

Season of the Construct sent players beneath the sands of Kehjistan to uncover the truth behind the Loom, an ancient construct built by Zoltun Kulle and his former collaborator Ayuzhan of Caldeum. Malphas, a malevolent demon, had seized the Loom and turned it against Sanctuary. Ayuzhan guided the player through the seasonal questline, which required a new character on the Seasonal Realm and completion of the Main Campaign, though players could skip the prologue to enter seasonal content directly.

The Loom's corruption produced two major gameplay additions: the Vault dungeon type and the Seneschal Companion, the season's mechanical companion system. Both were tied narratively to Zoltun Kulle's legacy and functioned as the primary endgame content loop.

Battle Alongside the Seneschal Companion

The Seneschal Companion was a mechanical construct players acquired during the seasonal questline. It could fight directly or provide support depending on how it was configured. Customisation used Governing Stones (which determined attack behaviour) and Tuning Stones (which added utility and enhanced the Governing Stone effects).

Each Seneschal accepted up to 2 Governing Stones and 6 Tuning Stones (3 Tuning Stones per Governing slot). The full stone pool comprised 12 distinct Governing Stones and 27 standard Tuning Stones of varying rarities, plus 2 Fabled Tuning Stones (Evernight and Genesis) available at higher tiers. Stones dropped from Vaults, Wardwoven Chests, and Construct enemies throughout Sanctuary. Collecting duplicate stones and fusing them levelled the stone up, increasing its potency. Build optimisation centred on pairing the right Governing Stone with complementary Tuning Stones to match the player's class skills. Players optimising their Seneschal loadout can compare Season 3 build carry options to find the right class setup for the season.

Deadly New Dungeons: Vaults

Vaults were the season's primary dungeon content: underground facilities built by Zoltun Kulle and Ayuzhan, corrupted by Malphas. They were filled with elemental Hazards and Construct enemies, an entirely new monster family introduced in Season 3. Entry cost Pearls of Warding, which converted into Zoltun's Warding on entry, a stacking blessing that diminished each time a Hazard was triggered.

Preserving Zoltun's Warding through to the final boss unlocked a Wardwoven Chest, which had an elevated chance of Legendary item drops compared to standard dungeon rewards. Players who cleared Hazards without losing Warding received the best chest quality. The endgame pacing loop centred on farming Pearls from open-world activities, spending them on Vault runs, and extracting Stones and Legendaries for most build types.

The Gauntlet: Leaderboard Competition

The Gauntlet was a weekly rotating fixed dungeon that tested players for a spot on seasonal leaderboards. The layout changed each week, preventing static optimisation strategies from persisting indefinitely. Only characters at the top difficulty tier could access it. Top performers each week earned a permanent record in the Hall of the Ancients, the season's durable leaderboard of elite runs.

The Gauntlet launched mid-season rather than at Season 3's start, giving players time to gear their Seneschal builds before competitive scoring began. It was the first time Diablo 4 had offered a structured per-class leaderboard, and it drew comparisons to Greater Rift pushing from Diablo 3. For players preparing to compete in The Gauntlet, a leveling head-start made a meaningful difference; explore D4 leveling boost services to close the gap quickly.

Quality-of-Life Updates and Season Rewards

Season 3 kept Helltides running near-continuously, a significant change from earlier seasons where Helltide windows were restricted. Players farmed Aberrant Cinders (the official currency name) from demons and used them to open Helltide Chests. The near-continuous schedule let players chain Helltide farming between Vault runs without waiting for a timed event.

PC players gained optional W-A-S-D keyboard movement in Season 3, a long-requested accessibility feature. The Season Journey offered unique rewards per chapter: legendary aspects, the Awoken Adamant Armor, and Scrolls of Amnesia that reset skill and Paragon allocations. The Battle Pass ran 90 tiers (28 free, 62 premium) and added armour sets, mounts, and cosmetic items. Tejal's Shop received updated cosmetic inventory for the season.
