Bone Shape

You touch a pile of inanimate bones of Medium size or smaller or a single inanimate bone, or section of a bone, no more than 5 feet in any dimension and form it into any shape that suits your purpose. So, for example, you could shape them into a weapon, idol, or coffer, or make part of some grander project, as long as the object is less than 5 feet in any dimension. You could also affect a skeleton such that, were it later to be reanimated, it could not move.  Resurrection magic that would work on someone reduced to a skeleton would undo any changes done to the skeleton by this spell.
