It's a waste of SP, really. It's one of those skills that sit on your skill tab but you never actually use. BSpS can fix the land rate, but really, in an emergency you'd UE, you wouldn't charm.
Thanks for the input. I have to agree with that reasoning. I had a feeling it was a waste when I tried it. I won't get any higher of it now. Anyone else got an option on it. I'd like to hear it.
