I guessed the answers from mushrooms i got save where it is in my inventory but in next save 20 minutes later i went to first town to blacksmith few things there and its not in inventory, probably i visited some vednor and selled it for mistake, i checked all of them in silverglen no one got this scroll so maybe in first town but i checked almost every main merchant hint is i buyed witchcraft scroll and legendary belt two new items after scroll vanished i tried to retrace who selling it with save when i still got scroll but no luck.
I also diged the place you mentioned with traps after already loosing scrools there is nothing there i guess game counted it when mushroom gave it to me and its blocked somwhere
