Prestige Class
 

Ok, need a few ideas of what to do.

All the MSRD base and prestige classes are running off the same class ability (AC bonus and a Fame bonus). I gave the classes a +1 AC and Fame bonus at a certain level. Works fine until you take the prestige class and then it adds all the bonuses up at total level and not by class level.

I think the reason is because they are sharing the same class ability. If so, would I have to make a AC and a Fame bonus for each class?

Thanks!

I'm not familiar with the systems you mention, but do they work like sneak attack? That is, each class calculates their own total, and then all totals are added together? I.E.

Class A gains 1 fame every 2 levels, Class B gains 1 fame every 5 levels, so a 5th level A 5th level B would have 3 fame? If so, you may want to look at the Helper.UseOwnLev tag for the class ability.
