Seems you have to have solved the "Borg collective" questline, where you have to help the outcast automata. Then you can farm the quest item to unlock cypher weapons at the mobs where "Euv'ouk" can spawn. My rogue didnt have it, I tried to kill more than 20 mobs, no quest item drop. For all my other alts it dropped after about 5 kills. German name for the quest is "Geräusche der Heilung"- The item is called Resonierende Scheibe. Probably resonating disc in English. This is the mob, that dropped it: Dreadsworn Sharpshooter Edit: Seems to drop everywhere: Just got it from the big beatle rare with another alt.
How the heck do you make a crossbow with LESS damage, and much less Dps than a 246 Ilvl? TOTALLY insane. Do they actually pay these devs?SO SAD!
From what I've been able to gather is you don't get access to these until you unlock Olea Manu. Once you do, you can get a random resonating disc drop that unlocks the weapons to begin dropping. I got my drop moments after I finished the last quest to unlock him.
