Laidbackgamer: I know thread necromancy is not viewed well in any forums, but seeing that recently another user had this issue and I found this thread while looking for a solution, I thought "why not kill two birds with one stone" and post what I found.
So, while searching online, I managed to found this on Abandonia: http://www.abandonia.com/files/extras/Realms%20of%20Arkania%20-%20Star%20Trail_Manual.zip
It is a document that includes all the miscellaneous information that was probably present in the missing pages of the scanned manual, since it has all the classes prerequisites and other information like the various diseases and a description of the skills and spells present in the game.
Comparing the class prerequisites in this manual and the ones in RoA1 manual, one can see that they have been changed between games, and as such the information present in RoA1 manual cannot be used when creating a new character.

rayfer: This issue remains unresolved. I had no problem creating characters in RoA 1 using the numerical guidelines in Appendix A....but in RoA 2 I cannot create a Rogue or Magician character within those same guidelines....did they change? The RoA manual 2 does not contain this Appendix.
