When the plane shift spell is cast, the cleric moves himself or herself or some other creature to another plane of existence. The recipient of the spell will remain in the new plane until sent forth by some like means. If several persons link hands in a circle, up to seven can be affected by the plane shift at the same time. The material component of this spell is a small, forked metal rod — the exact size and metal type dictating to which plane of existence the spell will send the affected creature(s). (Your referee will determine specifics regarding how and what planes are reached.) An unwilling victim must be touched in order to be sent thusly; and in addition, the creature also is allowed a saving throw, and if the latter is successful the effect of the spell is negated.
