In Diablo 4, world bosses are usually gatekeepers to the next World Tier difficulty, but for the upcoming beta weekends, Blizzard is giving players a taste of the Diablo 4 world boss Ashava. This devastating, massive creature has been described as an "enormous killing machine" by the developers, and you can face her in the Diablo 4 Open Beta if you know when Ashava spawns.
This article explains what you need to be able to take on the Ashava world boss in Diablo 4's Open Beta, as well as the dates and times she spawns, so ready those weapons, and let's get started.
Update on 29 March 2023: We've updated this article with the exact dates that the Diablo 4 world boss Ashava will spawn.
The Diablo 4 Open Beta has now ended and we look towards the game's full launch on 6 June 2023, or 2 June for those with Early Access.
Diablo 4 Ashava World Boss: Player Count & Level

In the Open Beta, Ashava will be level 25, so players will have to be close to or also level 25 to have a chance at defeating her, according to Joe Shely, the Game Director for Diablo 4. In a recent developer livestream update, Joe Shely explained:
One of the really cool things about the world bosses, you can just show up there. There will be other people for you to work together to defeat the boss. These are huge bosses. The camera actually pulls so you can get a better view of the battlefield and see other people fighting the boss. It has huge attacks that affect a very large area of the world, and it is all seamless, you just show up there. There will be other people, and you don't have to have a group or organize anything in particular.
To make it clear, up to 12 people can go against a world boss per server instance. The recommended level is 25 for the world boss in the Diablo 4 Open Beta.
If you manage to take Ashava down, there is a sizeable loot drop that awaits. However, this Diablo 4 World Boss doesn't spawn all that often and only on specific dates of the Open Beta.
Diablo 4 Open Beta Ashava Spawn Dates & Times

Those who have pre-purchased Diablo 4 will receive Early Access to the Open Beta from 17 to 19 March 2023. On the following weekend, the Open Beta will be available to everyone from 24 to 26 March 2023. However, Ashava will not spawn on all those days.
Ashava will spawn each Saturday of the Diablo 4 Open Beta weekends. This means Ashava will spawn on 18 March 2023 and 25 March 2023. The developers also noted that the Diablo 4 Open Beta world boss would only spawn four times a day on the days noted above.
Blizzard has revealed the exact spawn times of Ashava during the Diablo 4 beta weekends on each of the two dates above as: 10 a.m., 12 p.m., 10 p.m., and midnight PDT. Blizzard has revealed that during the Open Beta, Ashava will also spawn on Sunday, 26 March 2023 at 12:00am PDT.
At the time of writing, the exact spawn times are unknown, but we expect Ashava will spawn every six hours on 18 and 25 March. We will update this section once the exact spawn times become available.
