What is the mechanic to kill the new warzone boss "The Brainstealer"?

Question

With the introduction of the new warzone there is also this new boss that is like a brain he summons two kind of creature Fleeting Thought and Brain parasite, what has to be done in order to properly kill this boss?

Answer 1

1. Start attacking the boss, fleeting thought and brain parasite will spawn
2.  When the boss is at half its health, 2 pink balls (Mental Nexus) will spawn, one north and one south of the room, lure the fleeting thoughts so they are placed NEXT to the Mental Nexus, it has to be done to both nexus. We usually put a poison bomb with the Mental Nexus in the Center and we just lure the fleeting thought in the bomb area, RP lures one fleeting thought to the north nexus and EK goes to the south, also blocking the boss. The fleeting thought has a berserk like spell that harms the nexus hence why it has to stay next to it
3. After killing both nexus, proceed to attack the boss and when it is at 25% of its health, the nexus will spawn again. Repeat the mechanics and kill.
