Hey, I found a upgrade item for HK-47 in Nar Shaddaa, but he became very "nice" when gave it to him. He didn't want to kill people anymore. It was very cool. I did it out him and he became normal, but he gained wisdom. I got the upgrade from the guy in Nar Shaddaa who want me to explore traidroutes. Did anybody else found this and are there more of them?
