Ghoul Paralyzation in the original three books doesn't have a duration. Unless the referee is feeling merciful looks like the only way to remove it is through magic (spell or item). Luckily for Boog, my half-orc fighter character, Tim of Gothridge Manor was feeling merciful.
To me the Old School Renaissance is not about playing a particular set of rules in a particular way, the dungeon crawl. It is about going back to the roots of our hobby and seeing what we could do differently. What avenues were not explored because of the commercial and personal interests of the game designers of the time.
