All I'll say about the Nameless One's Rune of Torment arm tattoo is I've seen some hideous examples of ones that look like pencil sketches or just really poorly done, and they're embarassing.
The one my friend has, has been completely filled in, mostly with black ink... and whilst it took hours to do and cost a small fortune it at leasts look half reasonable. I say that, but part of my mind seems to remember it being vaguely cartoony so errrrrgh... lol
