Blizzard announced a Diablo 30th anniversary program for Diablo Immortal with returning events, rewards, bosses, balance changes, and free cosmetics. The underlying announcement was published by Blizzard Entertainment on July 27, 2026, and GG Bulletin has summarized it independently rather than reproducing the source article.
What was announced
The celebration begins after late-July maintenance and continues through August with consecutive Mirrored Jewels windows, returning activities, and additional anniversary content. The official source remains the authority for exact regional timing, eligibility rules, pricing, technical requirements, and any corrections made after publication.
Why it matters
A month-long structure gives active players a concentrated reward period and gives lapsed players a clearer reason to reassess the current live service. This is the part of the update most likely to affect players deciding whether to buy, return, subscribe, upgrade hardware, or change how they spend their time.
What players should verify
Before acting on the announcement, players should confirm the current product page and support information. Reward eligibility, server-local timing, monetized offers, event caps, and the balance impact of the accompanying class changes need to be reviewed in game. Live-service schedules, store listings, release dates, and platform features can change after an initial announcement.
GG Bulletin assessment
This is a confirmed, attributable development from Blizzard Entertainment. GG Bulletin classifies it as a source-backed platform update, not a rumor. We will revise the report if the publisher changes the schedule, scope, supported platforms, or technical details.
The source for this briefing is news.blizzard.com. No publisher article text, video file, or artwork has been copied into GG Bulletin; the local cover image is an original editorial title card.
