I don't get it. How could you brew the 2nd potion if, as you say, you could not read the book and thus not learn the recipe? I'm really confused what your situation is.
There is one potion to be found in the witch's cellar so even those without scholar/mystic tags can complete the quest, in a way. Being able to make a 2nd potion is just a bonus.
thing is i do this amazing thing thats called searching the interwebs to find the solutions on things i dont know. that being said the quest does not update to complete. i really dont understand how you cannot put any thought into that. hey lets just leave all quests marked as not resolved and that you helped no one in the quest log to really fill that thing up.
WHAT really p's me off is my main character can somehow read one half of the book and my other follower can read the second half, yet wait for this now. THEY CANNOT CONVERSE WITH EACH OTHER TO COME UP WITH THE RECIPE. really crazy huh.
Hey bro "me talking to lohse" i just read this book and got 1 half of a recipe from it but dang im not a mystic i cant read the second half, he replies well im a demon im not lohse in actual fact so sod off and ask another mystic. "but i thought u was a demon mystic lohse sidekick. HE GOES SILENT and attitude drops -100. what a crazy scenario.
