There are three world bosses in Diablo 4 that you can go up against with other players. These bosses spawn spawn in the open world and you can earn powerful loot from them so we strongly recommend participating in the boss events whenever they are available during your playtime. You will be alerted via your in-game map whenever a boss is about to spawn and you should start heading to the map marker a couple of minutes before a boss is about to spawn. Here is a quick guide on all the spawn times for Diablo 4's world bosses which you can refer to in case you want to take on some of the toughest foes in the game.
Diablo 4 World Boss Spawn Times
The three bosses that you can go up against are Ashava the Pestilent, Avarice the Gold Cursed and Wandering Death, Death Given Life. Even if you do not have friends to take on the world bosses with, the game offers
4:30 to 6:30 UTC (12:30 AM to 2:30 AM ET)
10:30 to 12:30 UTC (6:30 AM to 8:30 AM ET)
16:30 to 18:30 UTC (12:30 PM to 2:30 PM ET)
22:30 to 0:30 UTC (6:30 PM to 8:30 PM ET)
We recommend using the Helltides tool to stay updated on when the next world boss, Helltide or Legion Event will spawn. The tool also has a Discord bot that you can add to any server to be notified whenever an activity is live.
There are all of the locations that the bosses can spawn in:
The Crucible, Fractured Peaks
Caen Adar, Scosglen
Saraab Calder, Dry Steppes
The Seared Basin, Kehjistan
Fields of Desecration, Hawezar
When a boss is about to spawn, there will be a marker highlighting the location so you do not need to remember these spawn points. With the servers being heavily populated you will find multiple players joining to help you clear the fights. Once you are fully geared and have a high-DPS build, you might even be able to solo all three world bosses in Diablo 4.
