Sorry, if I did not make any sense I suck at english. Also when they attack they can kill the user or teleport them to a different further place (if they do that the weeping angel will have their HP increase). First I thought this monster was too hard to have in Skyrim, so I had this idea where there were a full spawn of them in an abandoned crypt/temple (If people wanted they can have them in the game). They're called weeping angels because they would use their hands to cover their face giving a 'weeping' appearance, but when they move they grew fangs and claws. When you look away this creature disappears and goes behind you and snaps your neck or with a touch move you into a different timeline, they did that because they would consume the potential energy the victims would otherwise have led. Sort of like an endermen (minecraft), slendermen, or SCP-173.

When you stare at it doesn't move, but when you look away it moves away or disappears. This monster is basically an angel statue. Weeping Angels was a creature that appeared in Doctor Who (Sci-fi series on BBC).
