There’s a pretty infrequent issue with Realmwalkers that might just cost you the entire event if you aren’t careful with your clicks!
A Relic of an Older Age
So here’s the scenario. You wait until there’s as little time left on the Realmwalker event start as possible, as usual, and head on over. The event starts and it’s all good. You’re chasing it around, killing mobs and towers. However, the big lumbering demon’s path ventures near a certain opening. You’re clicking all around destroying enemies left and right and accidentally click on it.
Welcome to a cellar. You remember those right? They were never really worth-while even at launch, and are now a 1-stop visit for the Season Journey? But no big deal right, just go out and continue your chase? NOPE! Unfortunately when you enter a cellar you’re probably going to exit into a new instance of the world map, meaning the Realmwalker event you were just a part of is gone!
