The movie is about a group of college kids and one of them (you don’t find out ’til the end) has a device that makes a wax voodoo doll. The person creating the doll(s) does all kinds of bad horrible things to the people in the film. Like one guy is jogging at night and he stabs or burns the doll’s joints and it’s pretty graphic what it shows happening to the guy. Another guy is at an indoor rock climbing place and he gets maimed pretty bad too. The guy with the voodoo doll just starts breaking off the doll’s limbs and the guy gets all beat up. The movie is in my digital library, I just can’t remember the name of it. Thanks!
