Impulse Drive?

Oh, and I tried to mention this in an edit because of the posting limit, but I guess it wasn't seen. What is the exact condition for gaining the 50% "Higher level class" bonus? Is it merely enough that you have a single combat class at a higher level than your current one, and you get the full 50%?

I believe your highest class needs to be 2 levels above, so If you have a 50, you get 50% bonus on any others until you hit 48. I could be mistaken and it's any time you're lower though, not 100% sure.
