Planar Servitor

You call upon a deity (or other divine power) to grant you aid in the form of a divine servitor of your deity's choice, with a level no greater than double the ritual's spell rank. The secondary casters explain what sort of assistance you need and why you need it; if the task is incredibly fitting to the deity, the GM can grant a circumstance bonus to the secondary Diplomacy check or rule that the check is automatically a critical success. If you use the ritual without good reason, the result is automatically a critical failure. If the ritual succeeds, you must offer the servitor payment depending on factors such as the duration and danger of the task. Payment always costs at least as much as a consumable item of the creature's level, and often costs as much as a permanent magic item of the creature's level to persuade a creature to fight alongside you. Your offerings should align with the personal tastes of the deity. You can alternatively name a being native to the deity's realm that you know personally, with the same level restriction. Such a creature might request something they personally want as payment.
