Not sure how hush hush the topic is considering it isn't really dealt with in help files.
I am wanting to know if any stats are related at all to natural saves? I assume each class/race has different mins/mass similar to race class stat differences? If my half ogre shaman, for example, is 24+ in some stat will I save vs spells slightly more. Will my horrid dex give me a disadvantage vs breath attacks? Etc.
