Completing the Mastering mission “Who is the killer?..”
How to start the task
Access to it opens automatically immediately after completing the last quest in the series called “If you wake up at midnight.” Just take a look at your mission log and start tracking it if it hasn't already been prioritized.
Exit the Dream World Hotel and examine the remains
Turn around and pick up the sticker, and then move to the next quest sign on the left side. Take the elevator and get to the VIP floor. Take out the group of enemies on your way and go through the door on the left.

After entering the spacious hall, inspect the three bodies – someone destroyed the monsters with thermal weapons. In the center of the room you can pick up the “Lost IV” sticker. Go to the next sign, passing through the double doors.

How to knock down the chandelier and clear the way
You will find yourself in a new room with a huge chandelier, which you have to knock down in order to break through the floor and create a new passage for yourself. First, go to the golden bowl and take 1 dream bubble. Then turn around and activate the bridge near the wall. Go to another plane and approach the second bowl to increase the number of your bubbles to 3.

Go back, interact with the first bowl again (so you have 3 bubbles) and go to the jelly to the left of the tools – use it to move to the wall. Run to the left and activate the second bridge to cross to another plane. Now create a third bridge and you can get to the ceiling and approach the chandelier.

How to defeat Sweet Gorilla
Break the chandelier chain to create a passage down. Go down and fight Sweet Gorilla. She attacks random targets, and if her victim has a shield, then the enemy hits himself (at the same time his defense may decrease). For this reason, it is highly desirable to have a good shieldman in your team.
This opponent can summon two Soda Hounds and gain Fortitude Defense (impossible to break through vulnerabilities). After the shield ends, the gorilla performs an area attack that deals significant damage to all your characters, so either shield them or heal them so that they do not die from this blow.
After dealing with the enemies, pick up the sticker ” Observation Room”, and then talk with Black Swan, who will be able to restore the memories of Firefly.
< /p>
Follow the Firefly
Examine the Firefly statues to listen to memories of her, and move towards the quest marker. Go down the stairs and open the door. Examine the new memory next to the chest, and then go through the door on the left.

Continue running forward and open the red door by interacting with the console. You will return to the lobby. Next, you will have a battle with the Stellaron hunter, Sam.
How to defeat Sam
First of all, prepare for a fight with him. This enemy is vulnerable to quantum, electrical and imaginary damage, so we advise you to take damage dealers of these elements to break through his resistance. However, at the beginning of the battle, the boss will receive the “Protection Vulnerability” status, preventing you from destroying its shield.

We advise you not to spend a lot of skill points and save your offensive superpowers until he goes into Secondary Combustion mode. In it, his defense disappears, but he receives a significant boost, consuming his own health during attacks.
You will need to use all your ults and skills to quickly break through the boss’s vulnerabilities and bring him out of a mode that is dangerous for you. However, be careful when using skills, as Sam can set them on fire, causing you to take damage when using them. Healing abilities will now heal less hit points.
Find Aventurine and follow him
After dealing with the boss, talk to Aventurine. Then interrogate Black Swan. After asking her all the questions, go in search of a KMM employee by going up the stairs and entering the corridor.
Watch the long video. This will bring the task and the entire chain to an end. As a reward, you will receive a 4-star light cone “Weaving Threads of Fate”, as well as 700 Mastery points, 80 star jades, 350 hour credits, 127 thousand credits, 12 traveler’s guides and a new melody.
