Of the multitude of powers imbued in each ring, only one is accessible to a casual wearer—a teleportation power allowing expeditious transport through Undermountain.
Ring Slot 3,400 gp
When you use a teleportation power, as long as the destination space is within range and you have seen the space before, you need no line of sight to that space. However, if you attempt to teleport to an occupied space, the teleportation attempt fails and the power is expended.
Utility Power (Teleportation) Daily (Move Action)
Effect: You teleport to any location in Undermountain you have seen before.
