Well, maybe not so much "normal" as it is harmless and sometimes useful. And there's a large variety. Someone could be Graced with something as abstract as fearlessness or not needing any sleep, or even disguise. I know a Graceling who was almost unmatched in unarmed combat. [That's partially a lie; her cousin Po had a different Grace altogether, but a fighting Grace is not uncommon.]

There are Graces that are of the mind as well. Those... most people tend to be wary of obviously.
