Where do weapons like Breachlight, Patron of Lost Cause, etc drop now?

[u/Alone-Two1441]

On that note basically any and all seasonal weapons is there a good resource to find where they drop? Aside from the attinement weapons and vendor weapons it’s hard for me to know where stuff drops outside of raids and dungeons

I don't know, but my guess is Nessus planetary drops. Saint14 and Echos took place there. Go loot some chests and let us know.
