So, KOM/KDM work a bit strangely with racial tracks.<br/><br/>Specifically, racial tracks completely replace everything you had from your class.  So normally as a sage, you'd be able to pick any two saves to be your good saves, have a poor BAB progression, and be able to pick any physical ability as your KDM and any mental ability as your KOM.  All of that is replaced by being a "vampire" race however, which sets your KOM to Dexterity and your KDM to Charisma.  (Note that if you pick a track that changes your KOM or KDM, that's applied after the race; so a barbarian with Path of Rage would have Strength as her KOM, regardless of racial tracks.)<br/><br/>However, you're not a "vampire", you're a mushroom girl, and while some things shouldn't be changed around too much for balance concerns, your key modifiers can switch freely.  So long as you can justify in-character why your key modifiers are what you picked, I'm fine with switching them to anything.  (The only limit is that they can never be the same ability.)
