Diablo Immortal × Berserk: Event Guide, Rewards & Patch

TL;DR: The Berserk collaboration (May 1–31) showers players with free crests, class weapons, the Crimson Behelit gem, a Zodd boss fight, a custom gem-pool system, golem familiars, double-XP winds, and a raft of dungeon/PvP fixes. Easily the biggest Immortal patch of 2025—miss it and you’ll fall behind.

Why This Crossover Deserves Your Hype

Berserk’s bleak fantasy finally meets Sanctuary’s eternal war, injecting fresh lore, weapons, and grind loops just when Immortal needed a shake-up. New systems mean real power gains, not just cosmetics, so even lapsed players have a reason to log back in.

Struggler’s Path Tasks & Rewards

Daily and milestone challenges drip more crests, set pieces, a Band-of-the-Hawk banner, Berserk emojis, and the stylish Eclipse portal skin. Easy wins—do them.

Weapon Cosmetics Worth Showing Off

Eight new models—one per class—headlined by Guts’ Dragon Slayer. These skins auto-scale with transmog, so fashion hunters won’t sacrifice DPS.

Phantom Market Armor Sets

The Berserker and Hawk cross-class outfits debut in the next Phantom Market. Expect a familiar price tag (around 1,700 Eternal Orbs) unless Blizzard doubles down for the two-for-one bundle.

Crimson Behelit—The Two-Star Gem That Plays Like a Five-Star

> 50 % HP: dealing damage triggers Wrath (+30 % damage, 6 s, 20 s CD).
< 50 % HP: taking damage triggers Mercy (-30 % damage taken, 6 s, 60 s CD).
Both procs fear nearby enemies for 1.6 s. Perfect for melee specs that dance around half-health breakpoints.

Survivor’s Bane, Eclipse & Zodd

Every other minute the arena plunges into total Eclipse—shadow hazards, elite waves, and a showdown with Nosferatu Zodd. Equip Crimson Behelit to unlock his enraged phase and tastier drops.

New Familiar: Earth-Bound Golem

Your first pet summon during the event is a guaranteed golem—fully new, not just a reskin. Mix-and-match armor plates let you flex unique looks once you roll the right traits.

Quality-of-Life Highlights

  • World-Boss Timer: Blood Rose and Mount Zavain now show spawn countdowns.
  • Destruction’s Call: Havoc Orbs add four team auras (haste, crit, heals, guardians).
  • Dungeon Affix Tuning: Butcher HP nerfed; chain/electric affixes fire less often.
  • Battleground: Guardian life-steal cut in half.
  • Size Buff Merge: All growth effects share a 150 % cap to stop stacking exploits.

Gem Pool Customization—Use It or Lose It

From May 1–22 you can whitelist 16 five-star gems (and boost odds on eight). The same goes for 17/8 two-stars. Set your wish list first, then pop your crest bundles for maximum value.

Five Quick Tips to Max the Event

  1. Trigger your double-XP token right before a dungeon marathon.
  2. Save crests until the custom gem pool is live.
  3. Level Crimson Behelit on an alt; transfer once it’s rank-ready.
  4. Farm Survivor’s Bane in a four-stack—boss HP scales, loot does not.
  5. Buy only one Phantom Market roll until pricing is confirmed.

The Bottom Line

This isn’t a throwaway crossover; it’s a meaty patch with real progression hooks and smart QoL tweaks. If you’ve been on the fence, now’s the moment to re-enter Sanctuary.
