How to get Psychopomp
Run the Pit of Heresy dungeon: 
Psychopomp sits in the loot pool of every encounter. Monument of Triumph gave the dungeon this pool, with tiered weapons and a new origin trait, 
Heretical Behavior.
Pit of Heresy is a Shadowkeep dungeon on the Moon, so you need Shadowkeep to enter it. Our Destiny 2 weekly rotation shows which dungeon is featured after each Tuesday reset.
