Well, I put some starting DCs on the materials, components, and one of the works (I'll try to do the rest later tonight). I realize they look high. However, these aren't intended for people without training to make. I'll likely make a feat that reduces the DCs (which would be granted at level 1 of the class form making necroclock devices). The DCs would be reduced by 20 for gear components, and 30 for devices.
