So as I look at class DC, it seems on the surface to be a no-brainer for dual class; each class has a DC specifically named for them, so they should level separately. However, I run into an interesting hiccup; as far as I can tell, many things that use a class DC will simply say "your class DC", instead of specifying, say, inventor class DC, and I don't see anything stopping you from simply choosing the higher of your 2 class DCs, even if it's not the one from the class you get the feat through. RaI this is obvious, but my tables tend to basically read RaW as the Bible, so is there anything I'm missing?
