Then, I'm asuming you do not give bonus on Geniality for seating but you give it "only" for the APP (modified by glory) roll, right?
What do you mean with "and if you are sitting at high table, you have an automatic +1 on top of this"? Automatic +1 on what?
Also, if there's a fumble on the roll, what is the result? -1 or -2 Geniality?
