I've made the changes for point 1 and 2.
For point 3, I would like to say yes since she bears no special favour to the Icefolks (she originally only granted her favour to one single young man who became her first prophet) and similarly bestow the knowledge to those who are talented regardless of races as well, since it was her duty in the first place. However, her direct manipulation abilities only work when they are within Frostfell and within her vicinity.
I can change it if you think it's too OP though.
