Actually, Garrett gets to add intelligence -and- charisma.<br/><br/>The Factotum LVL 3 special ability BRAIN OVER BRAWN allows him to use INT instead of STR and DEX for STR and DEX skills.<br/><br/>The Marshall LVL 1 ability to add CHA to INT skills increases this.<br/><br/>So, Garrett doesn't have a +17 to his ability...  because his charisma is currently boosted by +12?  Does that mean that Garrett, who has a 16 originally, now has a 28?  Or does it mean that he has a +15 modifier?
