Yes, I also assumed that the Bladesinger kit/class was somekind of dual class construct. Let me try to clarify:
The thing is that it was brought up in a PC initiated dialogue with Rivian that lead to me having the choice of paying 10.000 gold and thus becoming a "bladesinger". And the requirements I talk about is per what Rivian told me in those dialogues.
My question is not an attempt to acquire a bladesinger by the rules. I am only interested in knowing if above mentioned dialogue is actually leading somewhere or not.
I have never heard of 'the elven package mod' so I am also pretty sure it is not something that is caused by a MOD-cross or installation glitch.
Besides I would assume that if it is possible to create the "Bladesinger" that way it would also be possible to code a dialogue choice to affect the PC class similarly? I have no experience with modding so bear with me if I am not up to speed.
