What was Loot Reborn?

Season 4 (May-August 2024) shipped Patch 1.4.0 — one of the largest patches in D4's life. Tempering, Masterworking, a full Codex of Power rework (account-wide, permanent), Helltide Reborn with Threat meter, and The Pit of the Artificers all launched together. These changes applied permanently to the Eternal Realm.

When was The Pit added to Diablo IV?

The Pit of the Artificers launched in Season 4 (Loot Reborn) on May 14, 2024. It replaced The Gauntlet as the premier endgame content and introduced Obducite/Ingolith/Neathiron as masterworking materials.

What are Greater Affixes?

Greater Affixes were introduced in Season 4. Marked with an asterisk (*), they provide 1.5x the normal affix value. Items can roll with 1-4 Greater Affixes. Masterworking crits on Greater Affixes produce the most powerful gear in the game.

Season 4 — Loot Reborn

The turning point. Historical archive.

Season 4 — Loot Reborn — is widely considered the moment Diablo IV became the game it was supposed to be. Patch 1.4.0 shipped one of the largest overhauls in the game's life: Tempering, Masterworking, a revamped Codex of Power, Helltide Reborn, Greater Affixes, and The Pit of the Artificers all launched together. The community reception was overwhelmingly positive, credited in part to D4's first extensive PTR.
