Id just like to know how to make a custom class of my own creation compatible with synergies, more specifically the skill requirements, which are completely wrong when i play synergies.

I was unable to find a proper explanation or tutorial anywhere with only a few scraps of info without proper context. If a tutorial exists i would much appreciate being pointed in its direction, otherwise the major things i need to do to change my class so it works properly with synergies is what im after. It seems like everyone but me understands this, but i just cant get my class skill requirements to display as i set them or would like them to be.
