As of Diablo 4 gold  now, there are only three such World Bosses you can kill or be killed by—Ashava, the Pestilent; Avarice, the Gold Cursed; and Wandering Death, Death Given Life—with one spawning about every six hours (which one seems to be random). This means that if you miss a World Boss fight, you’ll have to wait a whole six hours before you can participate in the next battle. Talk about FOMO.

Or that’s what I would say if not for the Diablo IV World Boss Spawn Alert Twitter Account. Run by the tips and guides wiki site Game8, the account provides details on World Boss spawn times and locations. Per the pinned tweet, the game won’t indicate when and where a World Boss will spawn if you haven’t beaten the campaign, but you can still fight them if you’re in the right place at the right time, and the Twitter account will tell you just that.

Regardless, though, we put Ashava back into the dirt where she belongs. I collected my loot—all of which was weaker than what I’m currently using—cheered and thanked the other players, and teleported back to Kyovashad. I’d say that my revenge has been enacted. Mission accomplished.

In Twitter DMs with Kotaku, the person behind the account (who goes by Mr. Game8) said that between the real people tracking the encounters, the data calculations the team runs, and the overall World Boss patterns, he’s able to pin down the exact time when a boss will spawn and which one it’ll be.

“The game makes it extremely difficult to predict when a world boss is going to appear,” Mr. Game8 said. “There’s no clear indication of when one will come up, and even though there is a pattern, the spawn times are highly randomized. The only notification in-game for when a world boss will appear comes less than 30 minutes before the actual world boss appears. Most players are doing other things between playing the game and can’t stay at the computer 24 hours a day to wait for a world boss, but they still want to buy Diablo IV gold participate in them as there’s valuable rewards for them.”
