Req. OBSE v0020+
Through the marvels of OBSE, your character is no longer pigeonholed into one rigid class for an entire career! With Anyclass active, your character class automatically changes to match your current highest skills. In a nutshell, your seven highest skills will always be your class skills; the most common category among the your major skills will always be your class specialization; and your two class attributes reflect your strongest skills. (If you have Luck as a class attribute, it is never replaced.) An exhaustive system of tiebreakers ensures sensible results. Normally your skills are checked every 5 seconds, but no changes will ever be made while you are in combat.
What's the point? Characters evolve over time, and sometimes your initial class concept does not reflect your skills at level 10 or 20. However, those original skill selections still affect you: class and specialization skills increase faster than others. Anyclass allows your character to completely adapt, and get better at increasing the skills you've actually been increasing! Certain other mods also react to your class, and Anyclass ensures they get accurate info on who your character really is, regardless of who he may have been a lifetime ago in a prison cell. (In fact, the changes to your class attributes have no effect except to provide information to other mods.)
