Stone walk

Stone walk was a divine transmutation spell unique to clerics of Bane. It linked one stone area with another to permit multiple teleportations.

Effect
The Banite priest first needed to prepare the two areas to be linked. These must be stone surfaces some 5 feet by 5 feet (1.5 meters by 1.5 meters) in area and the work took one hour. If the stones were not damaged, they could be reused for future castings of stone walk.

On casting the spell itself, the stones were attuned to a chosen command word. Thereafter, anyone who stood on one of the stones and uttered the command word was instantly and reliably teleported to the other.

The stones functioned a very limited number of times: initially only twice, but more often for more experienced clerics. They also had a weight limit of 550 pounds (250 kilograms), or more for experienced clerics. Creatures that went over this were not transported, yet still consumed one use of the spell.

The gate seal spell negated the magic of the stone walk spell.

Components
In addition to verbal and somatic components, the spell required expensive material components. A paste composed on rubies and amber costing 2500 gp was needed to prepare each end of the link. Furthermore, a diamond also valued at 2500 gp was needed just to cast the spell. However, thereafter, activating a linked stone the required no additional cost.

History
Stone walk was one of a number of unique spells provided by either Bane or Xvim to their clergy, and it was granted by Bane after his revival in 1372 DR.

Uses
Agents of the Zhentarim regularly used stone walk to travel swiftly between Zhent-controlled fortresses.
