The dev. team has looked into increasing the number of methods to obtain these upgrade items, however, the stats on the completed weapons are very strong and they decided to put this on hold for the moment. With that said, we are aware that these items can be difficult to obtain so we’re looking into possibly offering them via login campaigns.
Edit Note: Mistakenly included VNMs (Voidwalker Notorious Monsters) as a means of obtaining these upgrade materials.
