Diablo 4’s third seasonal content update, Season of the Construct, commences on January 23 at 10 a.m. PST, introducing substantial gameplay innovations alongside narrative depth. This season delves into the enigmatic legacy of Zoltun Kulle, the brilliant yet unstable sorcerer previously featured in Diablo 3, whose technological marvels now become central to player progression.
The Construct represents a revolutionary gameplay mechanic that provides dynamic bonuses based on player interaction choices. This ancient device becomes corrupted by Malphas, a formidable demonic entity specializing in mechanical manipulation, creating compelling antagonist dynamics. The seasonal journey also introduces the Seneschal Companion system, allowing for unprecedented build customization through Governing Stones and Tuning Stones.

Season of the Construct significantly expands Diablo 4’s endgame through the Gauntlet weekly challenge and procedurally generated Vault dungeons. These additions provide fresh challenges for veteran players while offering substantial rewards for those willing to master the new systems. For comprehensive seasonal guidance, consult our Complete Guide to maximize your progression efficiency.
The Construct stands as a revolutionary seasonal mechanic, representing one of Zoltun Kulle’s most ambitious creations from his Diablo 3 era. This arcane apparatus functions as both narrative centerpiece and gameplay enhancement system, offering players strategic choices with tangible combat benefits.
Players will encounter the Construct within the Vaults, newly introduced procedurally generated dungeons filled with valuable loot and dangerous adversaries. Interaction with this device yields various temporary bonuses and permanent upgrades, creating meaningful decision points throughout the seasonal journey.
Malphas’s corruption of the Construct introduces compelling risk-reward dynamics. When corrupted, the device may provide enhanced bonuses at the cost of increased danger or resource requirements. Understanding these corruption patterns becomes crucial for optimizing seasonal progression and resource management.
Strategic Tip: Approach the Construct with different character builds to discover class-specific interaction options. Some classes may unlock unique bonuses unavailable to others, encouraging diverse playstyle experimentation throughout the season.
Malphas emerges as the season’s primary antagonist, a demonic entity possessing extraordinary control over metallic substances and mechanical constructs. His corruption of Zoltun Kulle’s creations establishes him as a formidable threat requiring strategic preparation and execution.
The Throne of the Eternal Sun serves as Malphas’s stronghold and the culminating stage of the Gauntlet, Diablo 4’s new weekly competitive challenge mode. This encounter tests player skill, build optimization, and adaptability under pressure.
Beyond his primary encounter, Malphas manifests unpredictably in various dungeons and world events, attempting to thwart player progress toward the Construct. These surprise appearances demand quick tactical adjustments and can significantly impact seasonal progression pacing.
Common Mistake: Underestimating Malphas’s area denial capabilities. Many players fail to account for his terrain manipulation, leading to unnecessary damage and failed encounters. Proper positioning and mobility management prove essential for success.

Governing Stones constitute the foundation of your Seneschal Companion’s combat capabilities, determining the mechanical ally’s primary and secondary attack patterns. These specialized artifacts enable deep customization of your automated combat partner’s role in your overall strategy.
Players can equip two Governing Stones simultaneously, allowing for diverse ability combinations. The twelve available stone types include Firefly (ranged explosive projectiles), Impale (single-target precision strikes), and Gyrate (area control rotational attacks), among others.
Optimization Insight: Pair complementary Governing Stones that cover different combat scenarios. For example, combine a single-target focused stone with an area-of-effect stone to handle both elite enemies and large groups effectively.
Each Governing Stone features unique scaling properties and synergy potential with specific character builds. Experimentation reveals powerful combinations that can dramatically enhance your overall combat effectiveness in various endgame activities.
Tuning Stones serve as enhancement modules that augment your equipped Governing Stones, providing additional combat utility and statistical improvements. This secondary customization layer enables fine-tuning of your Seneschal Companion’s performance.
The system permits up to three Tuning Stones per Governing Stone, totaling six potential enhancements. The twenty-seven available Tuning Stone effects range from damage amplification and elemental conversion to defensive buffs and healing capabilities.
Advanced Strategy: Prioritize Tuning Stones that complement your character’s weaknesses. If playing a glass cannon build, consider stones that provide defensive benefits or crowd control assistance.
Leveling duplicate stones through fusion significantly boosts their effectiveness. This progression system rewards consistent engagement with seasonal content and provides meaningful power increases throughout the season.
Time Investment: Expect to spend approximately 3-5 hours weekly farming Vaults to acquire sufficient stones for optimal progression.
Governing Stones and Tuning Stones primarily drop from Vault completions, with higher difficulty levels yielding better quality rewards. Shattered Stone, the crafting material required for stone creation, exclusively drops from Construct enemies within these dungeons.
The Gatehall, situated beneath Kehjistan, functions as your seasonal headquarters and houses the Seneschal Companion interface. This centralized location streamlines stone management, including equipping, swapping, and fusion processes.
Strategic stone combinations enable adaptation to diverse combat situations and playstyles. The system encourages experimentation to discover optimal configurations for specific content types and personal preferences.
Pro Tip: Focus on acquiring duplicate stones early to accelerate your fusion progression. Higher-level stones provide substantially improved performance, making duplicate acquisition a priority for efficient seasonal progression. For weapon-specific strategies that complement your stone choices, explore our Weapons Unlock guide for complementary gear recommendations.
The Seneschal Companion system, when properly optimized with strategic stone combinations, can contribute up to 30-40% of your total combat effectiveness in optimized builds.
Class Selection Impact: Your chosen character class significantly influences optimal stone combinations. Consult our Class Guide for specialized recommendations based on your preferred playstyle and specialization choices.
