How to make a Final fantasy 13 like leveling system

Can someone help me get a leveling system like final fantasy 13… I really like that leveling system. I am kinda new to scripting but I have a concept of how to create a basic hack and slash leveling system like kingdom hearts, but I would like to give my players more freedom than that if anyone can help me I will greatly appreciate it
