I am needing More help on npc file, regarding classes and rank

[cybersavior]

regarding the npc file

I understand all of the things you can do to an npc file

 

but there are two fields that I cannot get much more than a very vague description

 

 

1. what exactly does Rank do and is there a list of the ranks

2. as for the classes is there a listing of all the different classes and how they

behave
