"In Maxos temple you need to read the book that the librarian gave you in return for finding the book he was looking for. That and a couple ingredients (scales and blood) will turn Amdusias human."
The spell is in
that book. You just have to read the book, whilst having the scales and the blood in your inventory. I did that while I still was standing besides the Librarian.
