So I finally went through the totality of The Magnus questline and I wasn't able to accept rewards (skillbook and all) from Black Spirit's dialogue. Told me the "Quest was already accepted", so I closed the window. Now the quest is branded as "Unaccepted", so I can't forfeit it. It says to accept the quest from Black Spirit but no dialogue will show up about it. Does anyone have any ideas how to solves this ?

Thanks in advance !

Hi there, this happens when you try to accept the quest with a char that is below level 60. The quest can only be unlocked from level 60 onwards.

Thanks a million for the input, I didn't notice it was level sensitive!
Cheers!

Same happened to me but I was level 61 and still doesn't let me accept and can't find it in log anywere plz plz help

I assume you were on your level 61 Maegu? Maegu and Woosa do not have the abyssal revelation skill, so you cannot do it on these chars.
