It's a bit of both. In your case you could try to either higher your small guns skill or eat some mentats. With the next update, I will add another way.
problem is that i fight with melee weapons with current character... But will try using mentats then.
So how is it looking with fix of this quest? I got two times to same point. After visiting of all four stations and talking to each person are clues the same. He went to some next station. And when i try to talk to "shady person" he says just "Dont bother me". So where is the catch of it? Did i miss some NPC on some station or what did i do wrong? I tried it even with 10 charisma char and still the same.
Maybe the NPC isn't impressed by high knife skills.
So only SG can complete the quest?
Ok, but you done the quest after last update?Cuz before update I did with a melee char. Don't know now, cause Lexx said to raise SG skill only.
