Diablo IV

Season 14 · Patch 3.1.2

Event April 9, 2026

Diablo 4 has unveiled its latest collaboration, partnering with Doom: The Dark Ages to bring demon-slaying fans an exciting crossover event. The free Reliquary event is set to arrive in Sanctuary, allowing players to earn Doom-inspired cosmetics by ripping and tearing their way through demons.

The crossover represents a meeting of two iconic action franchises, combining the dark gothic atmosphere of Diablo 4 with the aggressive sci-fi demon hunting of Doom. This collaboration aims to reward dedicated players with unique cosmetic items that pay homage to the legendary Doom franchise.

What Changed

The Reliquary event introduces a new currency system called Dark Ages Currency. According to the Developer Update preview, players must collect a total of 900 Dark Ages Currency to complete the Reliquary and unlock all available rewards. The specific breakdown of how this currency is earned remains undisclosed at this time.

The Doom-inspired cosmetics available in the event include:

Shield Saw — A demonic shield featuring classic Doom saw aesthetics

Head of the Cyber Demon — A cosmetic head piece referencing the iconic Doom boss

Forsaken Gates Town Portal skin — Awarded for collecting all cosmetics in the collection

These items represent a unique opportunity for players to showcase their allegiance to both franchises through their character's appearance.

What This Means for Players

For dedicated Diablo 4 players, this crossover event offers a substantial goal to pursue during the content drought between major updates. The 900 Dark Ages Currency requirement suggests a moderate time investment, though the exact pacing remains unknown until players can engage with the live event.

The cosmetic rewards appeal to fans of both franchises, with the Forsaken Gates Town Portal skin serving as the ultimate prize for completing the entire collection. Players who have been waiting for new cosmetic opportunities will want to allocate time to complete the Reliquary before it potentially expires.

Build optimization may become less critical during this event, as players focus on efficiently earning currency rather than pursuing specific loot drops. The crossover provides a change of pace from standard gameplay loops while maintaining the core demon-slaying action that defines Diablo 4.

What's Next

The specific duration of the Reliquary event and its availability window have not yet been confirmed. Players should monitor official Blizzard channels for additional details regarding event start dates and any potential future phases or rewards.

Given the scale of this crossover, there may be additional content planned beyond the initial Reliquary release. The collaboration between Diablo 4 and Doom: The Dark Ages suggests potential for further partnerships as both franchises continue to evolve throughout 2026.
