Upon casting the spell over ten minutes, the teleportation circle appeared on the floor around the caster, or on whatever horizontal surface they stood on, with a diameter of 10 feet (3 meters). It functioned like the greater teleport spell. Any creature who stood within the circle was teleported to a designated location. This location could only be set once. If the caster tried to designate a location that was a solid object, an area they were unfamiliar with and lacked a clear description, or was in another plane, the spell failed.
The circle was discreet and very difficult to spot. The caster needed to mark the circle in some way to keep creatures from activating it accidentally.
Teleportation circles were extremely difficult to detect and disarm.
After the Year of Wild Magic, 1372 DR, the teleportation circle functioned for 170 minutes, or longer for even more experienced casters. After the Second Sundering in the 1480s DR, the version of this spell most commonly seen lasted for only a few seconds. Both could be made permanent: the more powerful 1372 version via a permanency spell, and the weaker 1480s version by being cast every day on the same spot for one year.
This spell required verbal and material components. After 1372 DR, amber dust valued at 1000 gp was required to cover the area of the circle. The post–Second Sundering version of the spell required that the circle be marked with rare forms of chalk and ink infused with gems.
