I've got an idea for a Typhoid Mary style Nurgle Apostate but i could use some help when it comes to figuring out what advances to take, etc.
The concept is a priestess who works her way into Imperial cults and ends up seducing and *ahem* transmiting Nurgle's 'blessing' to her congregation before moving on. She'd display no great outward mutation or overt sign of Nurgle's taint.
What i'm wondering is how do i balance the fellowship advances and the such with the Nurgle advances in order to stay aligned to the Grandfather, and also, do any of you guys have any good ideas for custom mutations? My GM is pretty open minded when it comes to custom mutations but it would be good to have some 'ready made' ones to bring to him.
Thanks in advance.
