The World Boss is a team pvm event that occurs every 6 hours. Every 6 hours there will be global announcement about the boss spawning and where the location is.
You can speak to the 
World Boss Announcer at home.
Each World Boss has over 20 million health so you will want to race to find it and kill it because only the top 10 most damage will get a drop!
The World Boss will either drop the World Box or World Box Keys. Both of these are untradable but you are able to exchange boxes for keys and vice versa at a rate of 2:1. On top of these two drops, you also have the chance to get a scroll that will reward you with the title The World Guardian. If you are lucky enough the World Boss will also now drop the World's Globe Pet.
