Creating new Races

[Panzermeyer]

I am working on creating some new races for my setting.

How do I create a racial ability that uses the Reduced Core Skills. I am creating that will not start off with a d4 in persuasion but will have that as unskilled. Not sure what to put into the effect that will create that.

Thanks
