I did the mod for Artu, he asked to get rid of all features except spells from School of Wizardy but it was faster for me to create a new script without cuts through original ert/erm. Is a very tiny mod, just one button and a few script lines.
I had not much time those days but also re-released Conquistador with options, so now you can select the internal difficulty at your taste. Uses SN.W vars so should be compatible with everything.
