Dawn of Damnation

"Only dread follows the trail of Skarn, Herald of Terror, on his path to cleanse the world of Sanctuary. Unchecked. Unchallenged. Skarn’s forces have ascended from the Burning Hells wreaking havoc across the Western Kingdom. Westmarch is the only bastion that halts the unrelenting wake of destruction. Who will confront the minions of the Lord of Damnation? Who will resist this evil insurgency? Heroes of Sanctuary, war is upon you! Beckon your allies, sharpen your blades, and hone your skills. Greatness and spoils await those who vanquish these foes in the Dawn of Damnation!"

- Mode description

Dawn of Damnation is a recurring event in Diablo Immortal.

Lore
The invasion occurred in the year 1270, when Skarn led his demonic forces against Sanctuary. They swept across Westmarch, before finally being halted at its capital.

In-game
The event lasts two weeks, themed around the player(s) fighting against Skarn's forces. Players must be at least level 30 to take part. Heroes who meet these criteria will be prompted to accept a quest in Westmarch that kicks off this event. After assisting Westmarch's forces in expelling Skarn's demons, players will be able to progress over the next couple of weeks through a series of daily missions (up to 42 missions per week) and event stages.

Completing missions can earn the player obols of the damned that can be redeemed to acquire treasures including legendary crests and gems in the Event Shop. Additionally, all heroes can reap additional obols of the damned when certain server-wide milestones are reached.

Development
The Dawn of Damnation was first introduced in the game's beta in December, 2021, to Korean and Japanese players.

Trivia

 * The events of Dawn of Damnation appear to contradict the lore of Diablo III and associated material, such as The Order. In the former, Justinian IV refuses to send forces to Bastion's Keep to fight "imaginary demons," despite his capital being invaded by them fifteen years prior. In The Order, Deckard Cain reflects on the lack of any demonic invasion in Sanctuary, despite the events of Dawn of Damnation taking place a mere two years prior.
