Deities guard their most powerful servants from the summoning spells of those who aren't steeped in the faith, but this spell conjures an inhabitant of the Outer Sphere with or without the deity's permission. You summon a celestial, fiend, or monitor of level -1, or instead an animal of level -1 that hails from the Outer Sphere, which you can give the celestial and holy traits, the fiend and unholy traits, or the monitor trait. It is anathema to summon a servitor whose holy or unholy trait your deity's sanctification does not allow, and the GM might restrict further types.
