Oh. I believe it is combined and not additional. By that I mean because it's bonus it does it's own damage after the inital damage which was done with the scaling.

It is also passive so you are always dealing 10% of your AP with no base damage once you put a point into W. On activate it gets base damage. The scaling ratio and then the passive damage.
