i'm using a copy of chronicles 1.2a and i want go to a classless system but i'm not sure how to do so.

would someone be kind enough to let me know where i can find a snippet that does this or let me know how to write the code to do this please?

i'm looking for something that lets me break the skills up into basic, common, uncommon and rare (or basic novice adept and master) and sets a limit on how many skills someone can learn from each group.

thank you.
