Boneshaker

By using a bone shaped fetish like a marionette, you take control of the target creatures skeleton. 

A creature has it's skeleton rattle within it's flesh, causing it grievous harm. The target takes 3d6 necrotic damage and must make a Constitution Saving Throw; if they fail you can move the target 5 ft in any direction of your choice, provoking attacks of opportunity if the movement would trigger it. The damage is halved and the movement is negated on a successful save. 

At Higher Levels. When you cast Boneshaker using a spell slot of 3rd level or higher, the damage increases by 1d6 and you can move the target an additional 5ft for each slot above 2nd.
