Diablo Immortal’s title character will finally make his debut on the mobile version of the RPG franchise later this month.

Diablo Immortal’s 3.2 patch will bring in the big bad, Diablo, in boss-fighting form on 13 December. Not only that, the update is going to be a big one, with new mainline quests and a new zone called the Shattered Sanctuary. The update will also add in new replayable dungeons, and new features like Challenger Dungeons and new Helliquary boss fights.

Here’s the full lowdown:

Diablo Immortal Patch 3.2

-Diablo Immortal will ring-in-the-holidays on December 13th with its most significant Major Update since launch, featuring the return of its primary antagonist, Diablo.
-This update, dubbed “Shattered Sanctuary,” introduces a pivotal new main-line quest and the largest new zone added to Sanctuary. Players can also expect multiple high-profile Boss Battles, new replayable dungeons, and more.
-The update culminates in an unprecedented epic battle against the Lord of Terror himself. Shattered Sanctuary marks the final chapter of the Age of Unmaking, the 2.5-year journey to destroy the Worldstone shards, but this is only the beginning of the future of Immortal’s mainline quests.

Diablo’s Return

-Diablo has been reborn with the power of the Worldstone shard, creating a land of terror, the World’s Crown, filled with demons and darkness.
-As he twists Sanctuary into a nightmare of his making, various forces have gathered together to launch a counteroffensive and face this great evil.
-The battle with Diablo is the biggest boss fight to date, with the most skills, effects, pressure, and monster density players have ever seen.
-Diablo comes equipped with a mix of familiar and new abilities, courtesy of the reality-altering Worldstone shard. Players must summon the light of El’druin to vanquish this relentless foe.

New Zone – World’s Crown

-World’s Crown is the new zone and a vast landmass, defined by mountains of corpses, pools of blood and acid, upside-down rain, and many other twisted horrors.
-Players must fight through vicious enemies, including fan favorites from Diablo 1, and Diablo’s personal lieutenants, before they can reach the Lord of Terror.

Other Features

-Shattered Sanctuary introduces more features, including Challenger Dungeons and new Helliquary boss battles.

• Challenger Dungeons are boosted dungeon runs that feature randomized modifiers. We wanted to introduce a new challenge for our most experienced players, and a way to earn extra rewards.
• New formidable adversaries arrive in the Helliquary. These bosses are inspired by the manifestations of Diablo and will put players through the paces. Bring your strongest abilities to quell these big bads!
