Creation
A creation effect manipulates matter to create an object or creature in the place the creator designates. If the effect has a duration other than instantaneous, magic or some other energy holds the creation together, but when the duration ends, the created creature or object vanishes without a trace. If the effect has an instantaneous duration, the created object or creature does not depend on any outside energy for its existence, so it lasts indefinitely once created.
