How to find Assimilated Demolishers in Destiny 2
Assimilated Demolishers are Vex bosses that must be summoned on Nessus. Defeating all three within the time limit completes the Forcible Disconnect Triumph and awards a number of Legendary Marks, so the key is knowing where and how to make them appear. You can summon the trio by activating a Vex beacon in the Watcher's Grave area of Nessus.
Head up the path toward the Cabal land tank and look to your right for a white Vex conflux beyond some Cabal machinery. Approach the conflux and follow the button prompt to activate the Assimilated Demolisher Beacon; the three bosses spawn immediately and you have five minutes to kill them.
The bosses simply have very large health pools. Killing all three solo is difficult but much easier with at least one other player. Prioritise the Wyvern first — it’s the most aggressive — then deal with the Minotaur and the Hydra. If you fail, wait for the conflux beacon to recharge; while you wait you can collect Strange Leftovers from Xur’s old spot on the nearby big tree.
