Where should I farm these two items.. been a few days now still no luck , also wondering if these items can be rolled off kadala

any item that is not bound to a bounty can be found at kadala.

best bet is to upgrade rares or grind it out in Grifts

That's what I've been doing hoping they drop for a few days now... I'll keep at it I guess , I just needed to be sure I can craft it off kadala cuz I must've wasted thousands of shards already
