GUIDE: Devil Square

Some servers have poor EXP multipliers. Don't worry! There's an event called "Devil Square" in all MU servers. Here, your strength will be tested against a hoard of monsters. These are the things you need in able to participate:

1. Jewel of Chaos

2. Devil's Key

3. Devil's Eye

You need an appropriate Devil's Key and Devil's Eye depending on your level:

 Devil's Key +1 and Devil's Eye +1 = Level 015 - Level 130 (MGs and DLs -20 Levels)

 Devil's Key +2 and Devil's Eye +2 = Level 131 - Level 180 (MGs and DLs -20 Levels)

 Devil's Key +3 and Devil's Eye +2 = Level 181 - Level 230 (MGs and DLs -20 Levels)

 Devil's Key +4 and Devil's Eye +4 = Level 231 - Level 280 (MGs and DLs -20 Levels)

 Devil's Key +5 and Devil's Eye +5 = Level 281 - Level 330 (MGs and DLs -20 Levels)

 Devil's Key +6 and Devil's Eye +6 = Level 331 - Level 400 (MGs and DLs -20 Levels)

And they drop from the following monsters:

 Devil's Key +1 and Devil's Eye +1 = Monsters over Level 3 (Such as Goblins)

 Devil's Key +2 and Devil's Eye +2 = Monsters over Level 36 (Such as Elite Yetis)

 Devil's Key +3 and Devil's Eye +3 = Monsters over Level 47 (Such as Shadows)

 Devil's Key +4 and Devil's Eye +4 = Monsters over Level 60 (Such as Devils)

 Devil's Key +5 and Devil's Eye +5 = Monsters over Level 70 (Such as Lizard Kings)

 Devil's Key +6 and Devil's Eye +6 = Monsters over Level 80 (Such as Iron Wheelss)

But if you're playing in a private server, chances are these items are also sold at NPCs. (yey!)

After obtaining the necessary items, we can now make the "Devil's Invitation" through the Chaos Machine Goblin. 

Talk to the NPC named Charon located at Noria. Present him the Devil's Invitation when the server announces that "The Devil's Square Gates are Now Open" or something like that (Depends on your server time).

Only 10 mutizens per level bracket are allowed inside every time the event is open, so be prepared to rush!

It is also allowed to have a party inside so that you can kill as much monsters as you can and obtain more experience. Players with most kills will be rewarded with more EXP so do your best!
