the Witch, or even after it, farming Lucent Hive Ghosts is something that can take a while, unless you know where to do it. In the event you are playing during Season 23, this is useful for the Bone Breaker challenge available during Week 6.
Farm Lucent Hive Ghosts
The best place to farm Lucent Hive Ghosts is the entrance to Vow of the Disciple in Miasma of Savathun’s Throne World. To reach it, go to the Patrol version of Savathun’s Throne World and go left. As you enter Miasma, stay hugging the left-hand wall to reach the entrance to the raid. You will find two Lucent Hive Lightbearers there. Defeat them to get two Hive Ghost kills.
The two Lightbearer Hive that spawn at the entrance respawn extremely quickly. Simply back up from the area (near where the Scorn spawn will do) and the Hive will reappear in a matter of moments. The only difficulty with this method is that you will be competing with whoever else is nearby.
Alternatively, you can run through the various Lost Sectors in Savathun’s Throne World. Each of these should have some Lucent Hive Ghosts for you to squish.
Once you’ve crushed enough Hive Ghosts, you should be able to continue on with the Season of the Witch campaign, complete the Bone Breaker challenge, or do some other activity that requires squishing the Traveler’s creations.
