History of Bump in the Night (triumph)

This triumph tracks the Pattern for Bump in the Night, a Legendary Stasis Rocket Launcher from Season of the Haunted (Season 17).

How to complete

1. Obtain Bump in the Night with Deepsight Resonance (red-bordered icon). Sources: Haunted weapon focusing at the Crown of Sorrow vendor, Armaments of the Haunted, Nightmare Containment drops, Sever missions, and the Presage Exotic mission when it is in the weekly rotator (up to 3 Deepsight weapons per week: Normal, Legendary, weekly challenge).
2. Open Collections > Records > Patterns & Catalysts and extract each Deepsight copy. 5 extractions (0/5) unlock the Pattern.
3. Then you can craft it (Glimmer, Resonant Alloy/Ascendant Alloy, Enhancement Prism).

Notes

The sources list different acquisition routes (older Season 17 ones vs current Presage); check in game what is currently available.
