Both of you are banned for not getting a room with all this back-and-forth banter.
And as for the individual ban: banned because not all lore states dragons as immune to the effects of magic, thus you are using a non-constant base of measurement to determine that you had the advantage. As a result, Kitsune's listed advantages being several degrees more reliable in terms of source (I mean, it's hard to argue away the existence of home-turf advantage and wit if used right) would have her as the victor here because at least her's have a baseline with which to be compared.

God, I need to sleep more so I don't get in to silly ban-wars.
