Enslave

Can be used once every ten days. Place a body part on an enemy below 5 HP to enslave them. They have no free will, and must obey any command you give them, unless it goes against their will or if they are incapable. This lasts until a lesser restoration spell is cast, removing the effect or if the caster wishes to set them free, but setting a slave free is a ritual. You need a pair of chains, a key, and a bird. It takes 30 minutes and after you are done, the slavery effect lasts for another 30 minutes, but weaker, just making them not attack you, however they do have free will.
