Diablo Immortal × StarCraft — Battle from Beyond the Stars Full Breakdown

Diablo Immortal's biggest cross-IP event in the game's history is happening right now. The Battle from Beyond the Stars — also called the Aeon of Stars event — brings StarCraft's Zerg, Protoss, and Terran factions directly into Sanctuary from May 13 to June 10, 2026. Three event modes, two new boss fights, faction-based leaderboards, and exclusive rewards. Here's how every part of the crossover works and what to clear before the event ends.

🌌 What Is the Battle from Beyond the Stars?

Battle from Beyond the Stars is Blizzard's first major cross-IP event tying Diablo Immortal to the StarCraft universe. The premise: the Zerg corruption is infesting Sanctuary, Protoss forces are launching incursions to halt the invasion, and Terran warfare tactics filter into the game's PvP modes. The event runs from May 13 to June 10, 2026 — meaning Adventurers have less than two weeks left to claim every event reward before the StarCraft factions retreat back across the stars.

The event is structured around three distinct content modes — boss fights, infested rifts, and a reworked Conqueror PvP mode — plus weekly faction-based leaderboards that reward your StarCraft allegiance with progression rewards. Each mode targets a different playstyle, making the event meaningful whether you focus on PvE, dungeons, or PvP.

⚔️ Aeon of Stars Boss Fight — Protoss Encounter

The headline encounter of the crossover is the Aeon of Stars limited-time Boss Fight, featuring two iconic Protoss units reimagined as Diablo Immortal raid bosses: the Tal'darim Templar and the Ascended Archon.

Both bosses feature devastating psionic abilities and precision combat mechanics that translate StarCraft's tactical depth into action RPG combat. The encounter supports parties of up to four Adventurers, making this one of the better cooperative event experiences Diablo Immortal has run recently. Coordination matters — psionic damage windows are punishing if you don't position correctly, and Ascended Archon's combat mechanics reward parties that bring proper damage roles and crowd-control coverage.

How to participate: Entry requires Challenge Tickets, available through standard gameplay and event-specific milestones. Special tasks await Adventurers who choose to test their builds against the Tal'darim's shadowed might — completing these unlocks additional event rewards beyond standard boss drops. Plan multiple attempts: the encounter is challenging enough that first-clear failures are expected, and Challenge Tickets can be re-earned as the event progresses.

🐲 Zerg-Infested Elder Rifts

Elder Rifts get a Zerg makeover for the event window. Enter rifts affected by a special Zerg affix and you'll encounter:

Zerg-themed enemies spawned throughout the rift floors
Feral Hydralisk boss encounter — a new boss fight unique to the event window
Psionic Storm ability — Adventurers gain a special ability that places a damage field on the ground at random, dealing damage to any enemies caught within

The Psionic Storm mechanic is the standout addition. It's a passive area damage source that procs throughout your rift run, dramatically improving clear speed for any build that handles single-target damage well but struggles with packs of mobs. The Feral Hydralisk boss is also one of the more memorable encounters of the event — the Hydralisk model from StarCraft translated into Diablo Immortal's combat is appropriately terrifying.

Run as many Zerg-infested Elder Rifts as your Empowered keys allow during the event window. The rewards include event currency and standard rift loot, so the runs are doubly valuable during the May 13 to June 10 window.

🏆 StarCraft-Themed Conqueror Mode — Faction Warfare

The biggest gameplay-altering addition is the StarCraft makeover of Conqueror mode. Before each match, Adventurers choose one of the three StarCraft factions — Terran, Zerg, or Protoss — and that choice affects what combat orbs you can collect during the match.

Faction Combat Orbs:

Stim Pack (Terran) — Increases Attack Speed and Movement Speed by 30% for 8 seconds. The fast-aggressive option for Adventurers who want to rush objectives
Poison (Zerg) — For a limited duration, all attacks fire poison projectiles that apply damage over time. Sustained pressure for builds that don't have native DoT
Shields (Protoss) — Grants a protective shield that lasts for a set duration or until it absorbs a set amount of damage. Defensive option for survival-focused play

Only orbs matching your selected faction drop during the match — choosing Terran means you can't collect Zerg or Protoss orbs in that game. This forces meaningful pre-match strategy: pick the faction whose orb best supports your build's weaknesses, not just the one you like thematically.

Weekly Faction Leaderboards: Conqueror also features faction-based leaderboards during the event window. Compete against other Adventurers within your faction for ranking — the top performers earn additional event-exclusive rewards. The leaderboards reset weekly, so even if you fall behind in the first week, you can still push for rank in the remaining time.

One useful change: all eight gear slots are accessible regardless of your party composition, eliminating the awkward gear-slot juggling that plagued older Conqueror cycles. Build your set, queue up, and play.

🎁 Event Rewards Worth Targeting

Battle from Beyond the Stars rewards span cosmetics, gameplay materials, and progression items:

StarCraft-themed cosmetic gear — Limited-time appearance items tied to each faction. These won't return until a potential rerun
Boss-specific drops from Tal'darim Templar, Ascended Archon, and Feral Hydralisk encounters
Conqueror faction leaderboard rewards — Top placements earn unique cosmetics and progression materials
Event currency usable in the limited-time event shop for additional rewards including Legendary Gems and event-exclusive items
Standard rift loot from Zerg-infested Elder Rifts

Prioritize the boss-specific drops and event shop purchases first — those are gated specifically by event participation. Standard rift loot can be farmed at any time after the event, but boss-exclusive cosmetics close their windows permanently on June 10.

📅 Event Timeline — Less Than 2 Weeks Remaining

May 13, 2026 — Battle from Beyond the Stars event began
Throughout the event — Weekly faction-based leaderboards reset, giving multiple chances for high placements
June 10, 2026 — Event ends, all StarCraft content removed from rotation

💡 Tips for Maximizing the Event Window

Choose your Conqueror faction strategically — Match the faction orb to your build's weakness, not your favorite StarCraft race thematically. A burst damage build benefits more from Terran Stim Pack than from Protoss Shields.
Save Empowered Keys for Zerg rifts — The Psionic Storm ability and Feral Hydralisk boss only appear in the special rifts. Standard rift runs don't include either.
Don't skip the Boss Fight even if it's hard — The unique cosmetics from Tal'darim Templar and Ascended Archon won't return after June 10. Wipe runs are still better than no attempts.
Coordinate faction picks with your party — In Conqueror, having two Terrans focus aggression while a Protoss tanks creates clear roles that win matches more reliably than three players running the same faction.
Push leaderboard rankings early — The first weekly reset is the easiest to climb. Later weeks accumulate competitive pressure as players optimize their builds for the event meta.
