Hello, I've got the massage in game, that I don't need the questline for betrayal from q to FP. Only talkin with a NPC. Is that true? THX and have fun.
Not that I know of. As I wrote in your other thread: You can change from one good city to another good city or from one evil city to another evil one by talking to the ambassador in your home city. And you can buy a betrayal token using Loyalty tokens so you don't have to do the quest to betray from good to bad or bad to good. -- It's 50 loyalty tokens and you have to be a Member (have a Gold subscription) to buy it.
to betray via npc is for same alignment cities only. i.e. from neriak, to gorowyn, or Freeport, or from kelethin, to new halas, or qeynos. to betray alignments, you must either do the questline, or buy a bauble from the loyalty merchant, as stated above.
