Horned ring

A horned ring was a magic item that teleported the wearer within Undermountain.

Description
These iron rings had small horns rising out of them that curved backward toward the wearer's fingers.

Powers
Horned rings were similar to Halaster's teleportation rings but teleported the wearer to different locations within Undermountain. The wearer was able to specify where they wished to teleport and the ring would break through any magical barriers, with the exception of prismatic walls or prismatic spheres, to get them there safely.

In order to recharge itself, a horned ring would absorb any incoming magic missiles and magical and natural electrical energy directed at the wearer. The wearer was completely protected from attacks of these kinds while wearing a horned ring.

History
Eight of these rings were known to exist with most of them being accounted for by Halaster's ex-apprentices.
