How to enter

 
To gain access to the dungeon, you must have reached at least level 200 and completed the quest series that begins at the Envoy of the Luciad Society Ruth.
 

Dungeon mechanics

 
Rooms that contain monsters always follow the same pattern.
Enter the arena and slay all the monsters as fast as you can.
Each time you or a party member slays a guardian, you will receive a message.
The message shows you a number and at the same time tells you the remaining time.
 
In case you missed the message, you can click on the cores that appear after killing the guards to see the number again.
 
You must now add up all four numbers to get a final answer for the room.
On the opposite side of the entrance, you will find 4 panels that you can use to give your answer.
 
The ground panels have two states, which you can change by clicking on them:
State 1: If the ground panels are low, they are considered false.
State 2: If the floor panels are high, they are considered correct.
 
If you get the wrong floor panel, you can simply click on it again and move it up or down.
 
With the final number you have calculated, you have to answer one of four different questions.
 
1: Is this number even?
2: Is this a square number?
3: Is this a prime number?
4: Is this a Fibonacci number?
 
As you change the plates, a message will be displayed to you and your entire group confirming whether the plate is true or false.
Example: You add your four cores from the guards and get the number 12.
 
1: True
2: False
3: False
4: False
 
If your answer is correct and then use the device in the middle, you will be sent one room further.
If you answer wrong you will be send to the same room again and have to clear it from the beginning.
 
There is a time limit of 30 minutes. For every minute you have left, the drop rate in the last chest increases by 1%.
Only one person needs to open the chest for all party members to receive a reward.
 
To help you out, here is a cheat sheet you can use.
 

Rewards and Dungeon Rules

 
Only one plate needs to be activated:

• If a number has multiple properties (e.g., the number 16 is both "Even" and "Square"), activating just one correct plate is sufficient.
• It does not matter whether the "Even" or the "Square" plate is activated, as long as one of the correct plates is triggered.
   
  Limited number of mistakes:
• Each incorrect attempt will be counted.
• The run ends after the fourth incorrect answer.
   
  Group Reward
• The group reward is randomly rolled between two options: Sky Pearl or Luciad Medal.
• All group members receive the group reward, and the time multiplier also factors into this.
   
  Chance for 1 Extra Item
• There is a 10% chance to receive 1 extra item (Soul Stone Essence or Alkahest).
• The extra item is given to a random group member (the lucky recipient will be announced in the chat).
