Mask of Painful Faces

This mask has the bearing of a face in pain when in its normal state.  The magic item allows the wearer to create the illusion of them being someone else but only their face changes.  This illusion can be changed only once per short rest.  All the faces that are created will appear to be in some sort of pain or mental struggle.  None of the faces will appear at peace.  It is not able to change the user's gender, nor will the wearer's clothing be altered in any way..  The wearer's voice can be altered, but all the voices will be gravely and sound like the person's throat has been damaged.

Unlike most illusion spells, if the user is touch in any way, the effect will not be disabled or change at all.  In fact there is a distinct chance the the person touching the user might still be fooled by the illusion.  With a DC 20 to make the determination that there is in fact an illusion on the user.  However, if the wearer is attack and takes any form of physical or magical damage, the image will flicker, but still not revealing the exact features.  Once the user has taken five or more hits, the mask will cease functioning until a short rest is taken.

This item must be attuned to function.  Once attuned the mask will not fall off, or can it be removed until the attunement has been ended by the wearer.  The mask itself has 10 hit points and no armor class, so it is easily destroyed even when worn.
