This powerful enchantment enables a wizard and a few companions to journey through space and across planar boundaries. The caster can affect one companion for every six levels he possesses, in addition to himself (rounded down). For example, a 23rd-level mage could cast the spell upon himself and three companions. The companions must hold hands as part of a circle that includes the caster. Any interruption of the circle during casting ruins the spell. Although there is no saving throw, the spell will not work on an unwilling or unconscious subject; if this is tried, the entire spell is ruined for all. Once the dweomer is cast, those affected by the spell can separate, though they must rejoin the circle to cross planar boundaries.
The prime function of the traverse is to allow the mage and companions to move to other planes, as if they had a small, personalized gate. Each planar boundary is crossed by all in unison; this requires one round of complete concentration. Each planar boundary crossed reduces the duration of the spell by one day. Furthermore, while under this spell, no person can cross a planar boundary by any means other than the traverse, including wish, gate, a well of the worlds, or even by an artifact. The spell grants certain lesser powers that can be used by the recipients, with no need to stay in a circle. These include the ability to fly, at will, as the 3rd-level wizard spell, and the ability to assume gaseous form up to thrice per day (with the general effects of the potion of gaseous form, except for duration, which is at will). The use of this spell in no way guarantees the safety of its users, either during their journey or once they reach their destination. The spell requires a circular platinum chain large enough to be grasped by all to be affected by the spell. This must cost a minimum of 10,000 gp for each being the spellcaster will transport.
The material component is at least 1,000 gp of powdered emerald for each subject, to be sprinkled in a circle enclosing the subjects. The chain is not consumed by the spell, but the powdered emerald is.
Notes: Very rare spell. Known to be in Tymessul's Enchiridion of Travel. (Updated from Dragon Magazine.)
