Feiton pass on character in progress

Hi, have anyone tried feiton pass on character that is not completely fresh? I have 460 ilvl alt character, that was knowledge transfered to vern. The game offers me to use feiton pass on it or should i rather use completely new char?

You can use it yes. It will take your character straight after Feiton main story even if he is at 460. Doesnt have to be fresh.
