Acasia's Dejection (triumph)

Acasia's Dejection is a pattern triumph for the Solar Trace Rifle Acasia's Dejection from the Root of Nightmares raid (a Lightfall raid). Five Deepsight Resonance extractions unlock its Pattern.

How to complete

1. Run Root of Nightmares and farm the second encounter (Scission) and third encounter (Macrocosm); those are the listed drops.
2. Alternatively, use 20 Spoils of Conquest on the end-of-raid chest to pick a Deepsight weapon, or solve the Deepsight chest puzzle for a random Deepsight drop.
3. Extract Deepsight from five red-border copies (progress 0/5). The weapon can then be crafted.

Notes

Reported drop encounters differ: some sources also list a final-boss drop.
