Any rule or section of a rule system that requires an acronym is probably too complicated. (I'm thinking THAC0, AOO, etc)
And, now, following the Joeskythedungeonbrawler’s rule an item:
A chunk of cloudy-grey crystal, as long as it is held the veil obscures the presence of the holder; no one will notice or remember their presence. Unfortunately, it also obscures the world to the holder; everything is a swirling grey, all sense of direction and memory of landmarks is lost. Only those most driven by vengeance or passion have dared try the Veil as a tool.
