Weapons that drop with Deepsight Resonance, which are identified by their red border, do two things: - Provide Resonant Elements, which are used in crafting weapons - Progress pattern unlocks For the first part, providing Resonant Elements, you can earn 300 if you progress the weapon through kills or activity completions. You can then inspect the Deepsight Resonance weapon and extract those 300 Resonant Elements. You can also earn 100 Resonant Elements by dismantling the weapon. The second part, pattern progression, happens when you extract the Resonant Elements as described above, as well as by breaking down the weapon (new as of the start of this season). Infusing Deepsight Resonance weapons into other weapons does not progress patterns, nor provide Resonant Elements. Not all weapons have patterns to unlock. You can find all weapons that have patterns by navigating to your Triumphs screen, which is left of your Character screen. On that screen, on the right side, you'll find a sub-menu called Patterns & Catalysts. In there, all patterns are organized by Primary, Special and Heavy weapon tabs. Hovering over each of the weapons will tell you how many Deepsight Resonance extractions need to be completed for each. Most require 5, and a few are are provided as part of a quest.
