Conjure Stone Servant

The caster touches a piece of solid stone or ore of some kind that meets the minimum required dimensions. the stone servant appears forms in the center of the stone and the remaining stone crumbles away to rubble. the servant will last for 2 hours before similarly crumbling to rubble. the servant will obey the caster through a psychic link. the servant will act autonomously to the caster's benefit unless commanded otherwise and will protect the caster if they become incapacitated. if the ore or stone used to create the servant has magnetic, conductive, or other properties, the stone servant will subsequently have those properties. for example iron ore would allow it to be magnetized or coal ore would allow it to be set on fire.
