Hello, I'm returning to the game and I have questions about the World Bosses... Could you tell me what time they appear or where I can see the times?

In advance, thank you for your comments.
Greetings

See https://garmoth.com/boss-timer

There are also boss discord channels.

I'm pretty sure there's an offical web page for boss schedules, but I haven't seen one in a while.

Thanks Entropoid!

I'll be watching for this. Greetings.

Press F2 key while in-game.

Also if you have an apple or android phone you can download the bdo app from apple store or google store and it has boss timers

you can select the bosses you want notifications for and it will notify you when a boss will spawn

it also has many other things bdo related as well as market place
