Diablo Immortal celebrates 20 years of WoW with battle against the Lich King

It’s hard to believe, but World of Warcraft is now two decades old. The original vanilla World of Warcraft launched back in 2004, and has since then received ten expansion packs with two more already announced and on the way. As part of the 20th-anniversary celebration, another Blizzard title, Diablo Immortal, is hosting an event to honor the MMORPG’s long history.

It would have been awesome to see this event in Diablo 4 as opposed to Diablo Immortal, but I’m assuming the recent release of the first Diablo 4 expansion, Vessel of Hatred, played a role in preventing that. Instead, starting November 13 at 3 a.m. local time, players will be able to take part in the Eternal War during the 20th-anniversary event and acquire event-specific rewards themed around World of Warcraft.

Here are all the rewards you can obtain in the first few tiers of the Eternal War in Diablo Immortal during the event:

• Mourneskull (Two-Star) Legendary Gem
• 1 New World of Warcraft Weapon Skin
• 10 Legendary Crests
• Frostmourne Weapon Cosmetic
• Icecrown Pathway Portal

The Frostmourne Weapon cosmetic and Icecrown Pathway portal were previous available in the Shadow of the Frozen Throne event, so it’s possible you already have them. As part of the event, players can then take on the pinnacle boss of the World of Warcraft: Wrath of the Lich King expansion, the Lich King himself. Considered by many to be the most famous—or infamous—character in all of Warcraft, fighting against the Lich King will reward players with Frozen Boons, a new currency that can be used to unlock various cosmetic Weapon Skins for each of Diablo Immortal’s eight classes.

I have to admit, these are some pretty legendary Weapon Skins from Warcraft lore including Gorehowl, Atiesh, and Thunderfury, Blessed Blade of the Windseeker. Yes, that Thunderfury, Blessed Blade of the Windseeker. Here are all the Weapon Skins each class can get:

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

For Diablo Immortal players interested in some PvP, there’s also the opportunity to partake in the Cutthroat Basin PvP event. Themed after the popular WoW Battleground Arathi Basin, players will be assigned to either the Horde or Alliance and then fight against the other faction across the Arathi Basin. Victory in the Cutthroat Basin rewards players with progress towards the Eternal War event as well.

The Diablo Immortal 20th anniversary event crossover with World of Warcraft starts on November 13 at 3 a.m. local server time and runs through December 11 at 2:59 a.m. local server time. Players who login to Diablo Immortal and join in on the fun on a Level 10 or higher character during the event will also receive a Treasure Nabbin’ Bag cosmetic in World of Warcraft: The War Within.
