If you wish to infuse it to another weapon, please complete the Deepsight activation in the detailed view first. Edit: Removed erroneous information.
Alright I just got another deepsight weapon, after inspecting I did receive the pattern progress so I guess I should have done that before. Didn't notice anything in-game saying I need to inspect in order to unlock deepsight progress... unless I'm wrong and there's a message but I definitely don't remember anything like that. Anyway thanks for your time
Unfortunately I don't, if I get any other deepsight I'll take a video before doing anything with it and I'll post it here.
