I reverse engineered a blue and got a purple with presence as one of its stats. Since it's a level 49 implant, I don't think many people would want one with a presence stat, so I decided to reverse engineer the blue again. Since I already got the purple from reverse engineering but with a prefix that I didn't want, can I continue to reverse engineer the same blue for a different purple prefix? I'm just wondering since I RE about 50 times but still had no success for a different purple.
