If its not to late to hop in here I would love to hear what people have to say. I believe it is missing formatting and has too much of a flavor based effect, but I would appreciate knowing whatever people think.
Subtlety Sheet
Aura moderate illusion;CL 5th
Slot ---; Price 10,000 gp; Weight 10 lbs.
Description
The Subtlety Sheet is a 10x10 canvas cloth, that seems unremarkable on one side, while the other side causes all creatures to subconsciously avoid noticing it. Anything hidden under the Sheet will be glossed over as background noise, requiring a DC 30 Perception check or else be ignored. Anything the Sheet obscures direct line of sight to is treated to the same effect, though this only applies to non-magical forms of detection. As the sheet makes the subject unnoticed rather than invisible effects like See Invisibility and True Seeing do not bypasses the Sheet’s ability. Creatures immune to mind-affecting abilities see the Sheet as a piece of canvas. The Sheet loses all functionality if it is torn, pierced, cut or otherwise damaged.
