Now you get those knolwedges doing the Loml quests, I got them, even got Duksoo to S first time, but you don't get them from replayable boss fights so my question is, is the way to get them to S to redo the whole questline with an alt? And if so, will the knowledges upgrade or do i need to delete them and hope for the best?

Basically i'm hoping someone has got those to S and can tell me how you do it.
