Planar call

Planar call was a powerful spell commonly used by wu jen in Kara-Tur. The spell was very rare outside Kara-Tur.

Effects
Using this spell, a wu jen summoned any creature from the planes. The creature was required to be known by the wu jen. There was a risk that a creature on another plane ignored the summons. If a powerful creature was summoned, such as a deity, they were not forced to respond, although some responded by their own volition. A successfully summoned creature was not under control of the wu jen and had the ability to return to their plane at their will. A wu jen was unable summon creatures while in the phlogiston.

Components
In addition to verbal and somatic components, the spell required material components, an incense and a piece of paper.
