Oh oh oh, I remember one of my friends getting some glasses for his tabletop character, due to the fact that he had a kind of paranoia for illusion spells, and everything that was out the normal thing was an illusion. So a \"friendly\" mage gave him some glasses that could show what was actually there, and what wasn\'t. Good idea, however the scanning of HP/MP is a very, very bad idea. Anyone can see if a monster is hurt or not, or it can be learnt over time. There\'s no need for special glasses there.
