Devil Square
Take on Kundun forces as they emerge in front of you in an endless wave of attacks. Alone or on a team that only the strongest will survive Devil Square.
Requirements
You need the Devil's Invitation that will match the devil square level you enter.
Creating a Devil's Invitation
You will need to create the Devil's Invitation using the 1x Devil's Key, the 1x Devil's Eye, and 1x Jewel of Chaos. Only items of the same level can be combined to create the Devil's Invitation for that specific Devil Square.
Step 01
After getting the ingredients go to the city of Noria or someone else with the Chaos Machine:

In Chaos Machine talk to the Goblin positioned in front of the machine, when talking to him will appear three options, Regular Combination, Chaos Weapon Combination and Item Combination Option. Choose the first Regular Combination option.
Step 02
After placing the ingredients in the machine click Combine and OK, the machine will create its wing depending on the success rate. In the event of a failure, the machine will consume all of its items.
An amount of zen is charged for the creation.
Congratulations! You created a Devil's Invitation.
