Much of the content that makes Lost Ark fun happens after you've reached the endgame. This comes when you have finished the main story and more so after you have hit Level 50.
One of the many things that you can do once you reach this point is a dungeon event known as the Cube. You can find these events in any major city where you can also do Guardian Raids and Abyssal Dungeons. But how exactly do you unlock Cube events?

You will first want to get a hold of an item called Entrance Ticket: Cube (Bound). You can obtain these while doing Chaos Dungeons as a drop. Once you have this, you can go to your Journal and select the Guides tab to find the [Guide] Public Announcement: Cube quest available to you.
The quest is as easy to complete as just walking up the Cube, which then subsequently unlocks the event. You will need one of these tickets every time that you enter so make sure that you stock up!
