How do I get into The Cube?
To get access to the Cube, Players will need to complete the [Guide Quest] Announcement: Cube. Which is available once reaching level 50 and obtaining an item level of at least 302. It should be in the Quest Journal <J> under the Guide Tab.
Entry into the Cube requires the item Entrance Ticket: Cube. Entrance Tickets are dropped from the 2nd floor boss of Chaos Dungeons. Only Chaos Dungeons completed consuming the daily resource Aura of Resonance will award a ticket as loot for completion.
See our post on Daily Checklists to learn more about Daily Resets.
From the Cube Interface window, players can enter alone, with their party, be automatically matched with other players queuing, or they can create a lobby on their own to select players they want to be in the party.
While it is advisable to enter as a group, keep in mind your group composition. It’s not 100% necessary, but having a Bard, Paladin or Gunlancer for their support skills will really aid in survivability.
Where is The Cube?

To get to the cube you will need to head to any of the major cities. On the map the Cube is represented by a Yellow Cube icon.

What’s Inside the Cube?
When you enter the Cube, there will be a Set Up Area. From here you can equip Battle Items and change your skills or select a pre-made skill preset. Once you leave this area, you will enter the dungeon and no longer be able to change your skills and swap battle items from your inventory.
Each floor has a timer. Once the timer runs out ghosts will appear and inflict a lot of damage making it much more difficult to clear. It goes without saying you should not get hit by these if you want to survive. Clean up the remaining monsters and you’ll be able to continue.

- Magenta Portal = Elite Floor: Mostly Elite monsters.
- Red Portal = Boss Floor: One or Two Bosses with a few Regular monsters.
