I did not play enough during Season 13 to claim the sidearm (Brass Attacks) or LFR (Threaded Needle) from the season pass. I've been trying to get them from focused umbral engrams this week but haven't had a single one drop. The focused umbral engrams that they come from [i]should[/i] have a 50% chance of dropping them. I've turned in way too many umbral engrams for this to just be back luck.
