Ancient forces threaten Sanctuary. Aided by your Seneschal Companion, hazard the many traps and devastating Constructs beneath the deserts of Kehjistan. Deep beneath the swirling sands, elemental forces are amassing for malicious whims of the demon Malphas. Only by descending far below the surface will you be able to cull this cursed threat from its root. Season of the Construct begins on January 23 at 10 a.m. PST. Prepare to uncover the powerful secrets of Zoltun Kulle's Loom with a new Dungeon type called Vaults, a seasonal robotic Seneschal Companion, and Weekly Leaderboards in The Gauntlet. Several key quality-of-life features—including almost constant Helltide events—arrive to help aid your conquests while fighting in the Vaults.

UNEARTH ZOLTUN KULLE'S LEGACY IN A NEW QUESTLINE
A new threat lurks deep beneath the sands of Kehjistan, where the Loom, an ancient technology—designed by Zoltun Kulle and Ayuzhan of Caldeum—has been usurped by the forces of evil. The Demon Malphas is responsible for twisting the Loom for his cruel whims. Zoltun's former companion Ayuzhan leads you through the treacherous Vaults, desperate to stop the formidable Malphas and his deadly constructs from overtaking Sanctuary. Travel to the Gatehall, a town center underneath Kehjistan that serves as your base of operations in the fight against the Constructs. The Gatehall is your conduit to access the deadly Vaults—riddled with elemental Hazards and Constructs, these Vaults are the key to harnessing the true potential of the Loom. Travel to the Loom to stop the threat at its source and defeat Malphas in a new Boss fight. To play the Season of the Construct Seasonal Questline, you must create a new character on the Seasonal Realm and have completed the Main Campaign. Take advantage of the Skip Main Campaign feature once you've completed the prologue if you want to jump right in!BATTLE SIDE BY SIDE WITH YOUR SENESCHAL COMPANION
Wield the power of the Loom by acquiring your very own Seneschal Companion, which becomes available during the Seasonal Questline. In Zoltun's vision the Seneschal compliments your adventures by engaging directly in the fight or aiding you dutifully on the sidelines.


Using magical Governing and Tuning Stones recovered from the Vaults and elsewhere in Sanctuary, augment your Seneschal to best suit your targeted build for Season of the Construct. Governing Stones determine which attacks your Seneschal can perform, while Tuning Stones will augment those skills and provide greater utility. You can equip your Seneschal with 2 Governing Stones and 6 Tuning Stones, one Governing stone for each attack and three Tuning Stones to augment the ability. There are 12 Governing Stones and 27 different Tuning Stones of different rarities to seek out in the Vaults to unlock the full power of the Seneschal construct.Tuning and Governing Stones can be acquired in a few different ways. Complete Vaults to earn one random Tuning Stone and seek out Wardwoven Chests to earn additional Tuning Stones-- both of which can be earned through various levels of the Season Journey. Both types also have a low chance to appear as drops when playing Vaults and Arcane Tremors. Defeating enemy Constructs within the Vaults will also grant Shattered Stone, which can be crafted into Governing and Tuning Stones at Jewelers found throughout Sanctuary.

To unlock the full power of the Stones, you will need to increase their raw power by levelling them. Collect or craft duplicates of the same Stones, fuse them together to grant experience and eventually level up your currently held Stones. Increasing the level of these stones increases the potency and ability of these attacks. Increasing the level of your Tuning Stones can add additional projectiles or augment the damage type they perform.

Once you've acquired your Seneschal, they'll follow you everywhere in Sanctuary until Season of the Construct ends. Further reading on this subject can be found here.
