How it works
The event changed between game seasons. The first tab is the newest version.
In MU's history, the Elf Tree once stood in Noria. Essentially, the tree still stands to this day, but now relocated. The Elf Tree was created by the Queen of all Elves, known as Aria. This tree, a sacred ancient monument, had the ability to produce Elves regularly.
Unfortunately, with time, Secrarium learned of the tree's great ability. Through dishonest tactics, he tricked Lugard into revealing the location of the Elf Tree. Having set his eyes on the tree's power of birth, Secrarium corrupted the tree and transformed it into what is now called the Immoral Tree. The Immoral Tree, now corrupt, gives birth to monsters.
The monsters horde grew to astronomical proportions, and the kingdoms of the MU continent had to combine their forces to entrap the Immoral Tree in a space of nothingness, where monsters could not escape. Monsters continued to spawn at regular intervals, from the tree, however after careful consideration Aria decided to make it a training arena for travelers.
Enter as one of 10 MUtizens to engage the forces of Kundun as they spawn in front of you in a endless barrage of attacks. Either alone or in a team only the strongest will survive the Devils Square. With the Devils Invitation, you are granted access into the Devils Square, where your strength will be tested.
How to play
Main Mission: Kill monsters and survive.
- When the event starts the monsters will instantly spawn all over the arena.
- You just have to kill monsters.
- Monsters will continue to spawn over 15 minutes.
- As the time progresses, the monsters which spawn will change and their difficulty will slightly increase.
How to enter
To enter the Devil Square, you need a Devil Square Invitation and go to Noria to talk to the NPC Charon which will send you to the event map and you must talk to the same NPC Charon.
Another way to enter is through the command window, if you press M and select Event Square you will be teleported to the event map where you can enter the main Mu events and in turn, you can enter the "Event Square" through the notification icon when the event is available.

In MU's history, the Elf Tree once stood in Noria. Essentially, the tree still stands to this day, but now relocated. The Elf Tree was created by the Queen of all Elves, known as Aria. This tree, a sacred ancient monument, had the ability to produce Elves regularly.
Unfortunately, with time, Secrarium learned of the tree's great ability. Through dishonest tactics, he tricked Lugard into revealing the location of the Elf Tree. Having set his eyes on the tree's power of birth, Secrarium corrupted the tree and transformed it into what is now called the Immoral Tree. The Immoral Tree, now corrupt, gives birth to monsters.
The monsters horde grew to astronomical proportions, and the kingdoms of the MU continent had to combine their forces to entrap the Immoral Tree in a space of nothingness, where monsters could not escape. Monsters continued to spawn at regular intervals, from the tree, however after careful consideration Aria decided to make it a training arena for travelers.
Enter as one of 10 MUtizens to engage the forces of Kundun as they spawn in front of you in a endless barrage of attacks. Either alone or in a team only the strongest will survive the Devils Square. With the Devils Invitation, you are granted access into the Devils Square, where your strength will be tested.
How to play
Main Mission: Kill monsters and survive.
- When the event starts the monsters will instantly spawn all over the arena.
