Diablo Immortal x World of Warcraft – What to expect

Here’s everything you need to know about the Diablo Immortal x World of Warcraft Crossover Event:

Diablo Immortal Legendary Eternal War Log-in Rewards

Log in to claim free rewards within the first few tiers of the Eternal War while the event is live, including the new Mourneskull (Two-Star) Legendary Gem, new World of Warcraft Weapon Skin, and more.

• Mourneskull (Two-Star) Legendary Gem – While equipped, dealing damage calls the spirit of the Lich King from within Mourneskull to drain the spirits of nearby enemies, granting you Royal Dominion, which increases all damage you deal, with a bonus for every enemy nearby. While Royal Dominion is active, your attacks will also unleash 2 Vile Spirits at nearby enemies every second that deal base damage to the enemies they haunt. Cannot occur more often than once every 20 seconds.
• 1 New World of Warcraft Weapon Skin
• 10 Legendary Crests
• Frostmourne Weapon Cosmetic
• Icecrown Pathway Portal

Players who have previously earned the Frostmourne Weapon and Icecrown Frame from the Shadow of the Frozen Throne event will not be able to obtain them again.

Embark on the Eternal War

From November 13 to December 11, players can earn Frozen Boons by completing daily tasks, competing in Cutthroat’s Basin, and facing the Lich King in the Fallen Citadel. Earning these Frozen Boons will help you progress through the Eternal War to earn coveted rewards in Diablo Immortal.

• Shadowmourne – Necromancer
• Gorehowl – Barbarian
• Thori’dal, the Stars’ Fury – Demon Hunter
• Truthguard – Crusader
• Atiesh, Greatstaff of the Guardian – Wizard
• Thunderfury, Blessed Blade of the Windseeker – Tempest
• Remornia – Blood Knight
• Fist of the Heavens – Monk

Players can earn weapon skins for each class, transforming them into the most legendary weapons from across Azeroth’s entire history. Completing the entire Eternal War event will earn players the “For the Horde” and “For the Alliance” Emojis.

Battle the Lich King in Fallen Citadel

From November 13 to December 11, players can go face-to-face with the Lich King, the leader of the Scourge, and defend Sanctuary from his chilling grasp.

To battle the Lich King, you’ll need to transport yourself to the Frozen Throne by earning Fallen Citadel Gates from Dungeon Content, log-in rewards, and as a rare drop from monster kills during the event.

Face-off in Cutthroat Basin

Players can also take on the ultimate PvP test between the Alliance and Horde. The Cutthroat Basin is inspired by the look of Arathi Basin, complete with Mill, Smithy, and Stables, and capture these for your side to edge towards victory.

Claiming victory within the Cutthroat Basin will earn you progress towards a Horde or Alliance banner depending on which faction you’ve chosen to represent.

Clash of Saviors Limited-time Event

From November 6 to November 17, adventurers over Level 30 will receive a 100% boost to experience gained from Battle Pass levels in Diablo Immortal.

The following rewards will be available on log-in to Diablo Immortal:

• Day 2, November 7: Rare Crest
• Day 4, November 9: Telluric Pearl
• Day 6, November 13: Legendary Crest

Murloc Invasion Familiar Skin

During Eternal War, players can claim their own Murloc Familiar Skin, which has unique Master Angler trait, occasionally doubling the fish you catch.

If you’re feeling that fortune may favor the bold, you can even try to earn the elusive Murloc Tidelurker skin.

Betrayer’s Bonds Phantom Market

The Betrayer’s Bonds Phantom Market is available from November 13 to December 11, which holds the power to transform you into the Betrayer—Illidan—himself.
