that is probably the closest thing they’ve done to Whisper of the Worm since that mission famously launched on Io years ago. It’s the way you unlock and eventually farm the exotic class items on each class, and it’s…more complicated than say, running a harder version of the finale mission Excision over and over. Rather, it’s a mission called “Dual Destiny.”You need to complete Overthrow in full in each region, The Landing, The Blooming and The Impasse.
After each Overthrow boss is beaten, there will be some dialogue and in the corner it says a Secret Keeper on the Witch Queen has spawned somewhere on the map. This is a Taken Wizard on each map that you will have to find and kill before the five minute Overthrow reset timer is up using a different sort of mechanic.– The somewhat hard to get to area in the back of the map that is sometimes marked by a Taken eye when there’s an Overthrow event in there.
Once there, you will see indicators for two chunky Subjugators nearby. You have to kill them to about half, they teleport away an leave an orb you have to go dunk back where you came from. There is a timer on this part but provided you can do halfway decent damage you should be fine. I did it solo and I had about 2:30 left on the clock. So yes, the entire unlock part can be done solo, but the quest itself cannot.
Once you beat the mission you will collect your class item from Ghost, and it will say that you can farm the mission itself for more or there is now a chance class items will drop from chests in Pale Heart. You will have to beat the mission at least once on each class to get the chest drop ability on those other classes.
So there are your two options. You can farm the mission for a guaranteed drop, but this will always require a second person and comms. Or you can farm chests from the zone, from Lost Sectors or from Overthrow. There is bad luck protection here and higher tier chests are worth more but I’m not sure what the overall drop rates are. It’s…not an ideal setup for farming an item with 60 possible combinations, but here we are. Fortunately, the mission itself is one of the best they’ve ever done.
