Passage of the quest "Date’s Challenge"

How to start a task

To do this, you must first go through Labyrinth in the Temple of Eternal Night. As a result, a grate will open where you can jump. At the bottom you will find the ghost of Date (it will only be visible in the Eternal Night mode). Talk to him and agree to take his test to get a new certificate of approval.

How to get through the maze in The Serpent’s Heart

Teleport to the specified location. The required puzzle is located under a huge grate. Use the previously obtained key to open the passage. Jump down. Now you have to solve the riddle of the labyrinth. We have divided it into several phases in order to more clearly show all the necessary actions.

Note: If you have already changed something in the room, then try resetting the settings by logging out of your account, waiting for 15-20 minutes, and then logging back into the game. You can also use the user's solution left in the comments to the article. At the end, you should have the following diagram:

• | #
• . | .
• # |

Where,

• | - wall
• # - lattice
• - night wall ( blue )
• . - Nothing

First phase:

First, you will need to switch to White Night using a device placed next to the closed barrier with a luxurious chest (if you already have the desired time of day set, then you do not need to switch anything).

Now run to the opposite side of the device and activate the lever on the column. Run to the right of the lever and hit the triangular mechanism 2 times with a melee attack, that is, the wall should move 2 times.

Second phase:

Return to the previous lever, which is located on the opposite side from the Night Changer, and interact with it again. Now run to the left of it to another triangular mechanism and hit it only 1 time.

Go to the side where there is a blocked chest and a device for changing the night. There will also be a lever on the column - activate it. Then run to the right of him and attack the triangular mechanism 2 times.

Third phase:

Return to the side where the closed chest and the night changer are located. Again interact with the lever on the column so that it looks down. Next, run left to the triangular mechanism and hit it 1 time.

Now run to the device and change the time to Eternal Night. If you did not make a mistake anywhere, then the Hurdle from the luxurious chest will disappear, and you can examine it. In it you will find the new Date’s Medal of Recognition. You will also unlock the achievement "Not enough communication...".

After solving the maze puzzle, return to Date, who is still in the Temple of Eternal Night. Go downstairs and chat with the ghost. Then open the chamber of secrets by going up the steps and unlocking the Achievement: Gate with the help of the certificates of approval previously collected.

In this small room you will find a rich chest, inside of which lies the book you need. In addition, completing this quest will reward you with 200 Adventure Points, 30 Source Stones, and 2 Hero XP.
