Diablo 4 Realmwalker event explained

What is the Diablo 4 Realmwalker event? Those familiar with Diablo 4 will feel right at home in an overworld event - huge bosses roaming the environs are old hat. A new addition with the Diablo 4 DLC, however, brings back an old foe - the Realmwalker - and tasks you with taking down these hulking beasts. It doesn't end there, though, as there is plenty to explore even after you're victorious in battle.
For those taking the plunge into the Diablo 4 DLC - and why wouldn't you after reading our glowing Diablo 4 DLC review - the Realmwalker world event is a great opportunity to test your Diablo 4 build and earn some valuable loot in the process. Here we have the frequency and times of the event in the RPG game, plus what you need to do once you've downed the Realmwalker.
