Profane Worm

Profane Worms are hidden collectibles in the Oblation Exotic mission chain. There are nine in total, spread across the three missions: four in Bloodline, four in Soulfed, and one in Immolation. Each Oblation mission has its own worm locations, such as behind a cooling pillar in Bloodline, in a niche in the First Drop Room in Soulfed, and on the left side of the Final Arena in Immolation.

Profane Worms are per character, so each alt must collect its own. A guide advises completing all three missions in one run, because leaving resets mission availability. The sources are inconsistent on whether collected worms persist after a wipe.
