Blizzard Entertainment has announced a massive crossover event for Diablo Immortal, merging the dark fantasy of Sanctuary with the interstellar chaos of StarCraft.

Titled “Aeon of Stars,” the event runs from May 13 to June 10, 2026, introducing new gameplay modes, rewards, and enemies inspired by the RTS classic.

New Challenges and Dungeons

Players will battle through Infested Rifts, swarming with Zerg enemies and a unique boss, the Feral Hydralisk, while wielding the special Psionic Storm ability. The Dark Ascension dungeon pits adventurers against the Protoss Tal’Darim Templar and Ascended Archon, reimagined with deadly psionic powers.

The event also introduces weekly faction leaderboards and a special Conqueror Mode, where faction‑themed shrines grant combat orbs tied to Terran Stim Packs, Zerg poison projectiles, and Protoss shields.

Legendary Gem and Rewards

At the heart of the Diablo Immortal crossover lies the new Baneboil Legendary Gem, which conjures explosive Banelings that cover enemies in corrosive acid, amplifying damage taken.

Additional rewards include:

• StarCraft‑inspired avatar frames, stickers, and portals
• Weapon transmogs themed after Kerrigan, the Queen of Blades
• Legendary gear and set items with selectable affixes
• Bound Empowered Immortal Keys for milestone progression

Become the Queen of Blades

Through the Phantom Market, players can embody Kerrigan herself, commanding the Swarm with blade‑sharp precision and unyielding authority.

New crossover familiars also arrive, including the Protoss Immortal and the ferocious Zergling, each offering unique combat perks.

Availability in Diablo Immortal

The Aeon of Stars event begins May 13, 2026, and runs until June 10, 2026. Adventurers can log in to claim free rewards, dive into crossover dungeons, and defend Sanctuary against the Swarm.
