You command an immortal creature whose level does not exceed yours. The subject of this ritual must be able to see and hear you and must remain within 5 squares of you for the entire time necessary to perform the ritual. Because most creatures do not willingly submit to this ritual, you must usually make the creature helpless or restrain the creature by means of a Magic Circle ritual. Unless it is prevented from doing so, the creature can leave at any time. Finally, you must be able to communicate with the creature, or the ritual automatically fails.
