Diablo 4's Season 3 Set to Launch with New Questline, Dungeons, and Robot Companion

The upcoming season introduces a new boss battle, quality-of-life updates, and Vaults that incentivize strategic gameplay.

Diablo 4's Season 3, titled 'Season of the Construct', is set to launch on January 23, 2024, introducing a new questline, a new base of operations underneath Kehjistan, and a new type of dungeon named Vaults.
The season's storyline will culminate in a new boss battle against a massive, stationary construct Malphas has possessed, one that wields elemental attacks and various traps to dish out death to players.
Players will acquire a spider-like robot called the Seneschal Construct, which can be equipped with two core abilities, called Governing Stones, and six ability modifiers (three for each Governing Stone) called Tuning Stones.
New leaderboards and quality-of-life updates will also be packed into Season of the Construct, including an extra Stash tab, WASD controls, and UI improvements.
Vaults, a new type of dungeon that houses a new monster family: The Constructs, will incentivize players to take their time instead of simply blasting through. Vaults offer yet another way for players to show off their mastery of the game.
