Transmog Idea: Vanishing Scroll -- removes the item's model from view
A lot of games around use a vanishing dye item that makes whatever you use it on invisible.
Some xmog sets would be better if you could turn certain pieces invisible... such as belts, gloves or boots. Or if you wanted to remove the xmog of a weapon to make it look like you were unarmed could be a cool effect if someone was trying to build a monk-type set.
This could be added to the current transmog sets and also sold on the site for the same price as deception scrolls (10c).
