Fairly simple stuff. mostly common sense "use whats closest" but some actual mechanics tossed in to to ease some things.
I was expecting something more... robust? Dont know?
I never got why people needed anything more robust than that.
It's not like you're converting your D&D character to another game. So robustness is not needed.
Yeah. I know that. But there are some changes between the two that could have been addressed a little more. It works as is.
