Brick of Poor Impulse Control

Origin
Found after a series of broken windows and two assaults in Florida, each committed by different person.

Effects
As soon as physical contact is made with the brick, the victim will instantly grab the brick and fling it towards the most breakable object within armshot. This effect happens too quickly for most people to react, though it is possible through focus to drop the artifact before it can be thrown.

"Most breakable" is usually objects made of glass such as windows or electronics, although in the absence of such it will default to being directed at the nearest human head.
